Fair Assessment

“All assessment is a perpetual work in progress.”
Linda Suskie

Last week we had a look at an endgame from one of our club games. The article is available HERE The position in the spotlight was this one:


Neither player did a very good job assessing the position (White was far too pessimistic, while black was too optimistic) and a number of moves later they reached the following one. How would you assess it?

White is still down a pawn which is surprising after being on the verge to even up the material in the first diagram. We made the observation it had to play aggressive. That did not happen and the main reason was poor assessment: she considered her position was lost!… You do not need a lot of endgame knowledge to observe now a number of differences:

  • The d6-pawn has advanced only once; pushing it towards promotion should have been the main focus
  • Kb7 is stopping Ra5 from reaching the 8th rank and help with the pawn promotion
  • Black’s pawn chain is still alive and far more dangerous now with the passed e4-pawn

Your chess sense should tell you black is back in the game and has a fighting chance. Now imagine you’ve been playing this game and whatever you felt in the first position, this one feels worst. Key is in such moments to calm down, reset and see what can be done to still achieve a good outcome. Have you ever been told of being too easy to play against? That means in tough situations or when things are not going in your favour, you cannot stop the slide and put up a fight. It is possible white was aware the latest position was worst; unfortunately it did not cross her mind to look for a way out. You might say that is impossible: white might just as well resign, saving time and effort if it accepts her faith. That is true except there’s always one hope we all have: the opponent might blunder. Of course you need to put up a fight and give it the opportunity to do so. Very rarely opponents blunder on their own.

Going back to the position a fair assessment should include a way out of it. White must eliminate the dangerous black pawns even if that means losing the important d6-pawn. Once white has that, it could look one more time to see if there’s more and if finding nothing, it should settle for a draw. It would be better than losing as it happened in our game after they reached a Black queen for a White rook type of endgame. In retrospect Black could think he was right all the time to think he was winning. That would be wrong; a fair assessment is needed at all times regardless of the outcome.

“What say you?” The 1 minute challenge (11)

“A wise man can learn more from a foolish question than a fool can learn from a wise answer”
Bruce Lee

A quick reminder about how to do it:

  • Have a look at the position for 1 minute (watch the clock)
  • Think about the choices in front of you and pick the one you feel it is right
  • Verify it in your mind the best you can
  • Compare it with the solution

Endgame play continues to be a tough nut to crack as I can see week after week at our club. I asked both players about this position and got the following answers:
Mengbai: “Don’t know. I guess I am losing”
Steven: “Don’t know. Winning?”
Have a look at the position (White to move) and decide for yourselves.

It is an interesting endgame, one you could encounter quite often at club level. Going over the position we can see the following important aspects:

  • Black is up a pawn
  • Kf4 is by far better than Kg8; the rather obvious Kf4-e5 would put it right in the center, supporting the d5-pawn
  • White has a passed d5-pawn, while Black has a passed a7-pawn; d5 is much stronger since it already is on the 5th rank. Black stands to lose the a7-pawn fairly quickly
  • Rd1 is pretty much tied up behind the passer but if White is not playing aggressive, it could swing to the 2nd row and possibly capture some white pawns in the process; if Black captures the f2-pawn and there is no imminent win for White, the e4-pawn becomes a passer and a threat
  • Rc5 is not placed in its best position but working together with the d5-pawn and its king, could make it very useful

Did you have something similar coming out of your analysis? How about a plan of action for White? In my opinion, after Kf4-e5 the combined threats of promoting the d5-pawn and back rank mating Kg8 (when it moves over to stop the passer) are overwhelming. White is simply winning here. The only challenge is to find the right moves and play aggressive.

In the game White managed to win the a7-pawn but her play was very tentative. I am not sure what was she concerned about when her passer reached the d6-square and stayed there longer than needed. Probably it is a good thing I had to watch other games meantime and missed a number of moves played. The simple line below shows a straight forward way for White to win. Next time we are going to look at the last part of this endgame.

“What say you?” The 1 minute challenge (8)

“A wise man can learn more from a foolish question than a fool can learn from a wise answer”
Bruce Lee

A quick reminder about how to do it:

  • Have a look at the position for 1 minute (watch the clock)
  • Think about the choices in front of you and pick the one you feel it is right
  • Verify it in your mind the best you can
  • Compare it with the solution

Are you ready? Here it is: black is a pawn up and looking for the best plan to get the win. What should Black do?

This was an interesting team voting game because of what followed. We had a very passionate discussion at this point about those options listed. It continued the following 3 moves and I just gathered the most important thoughts shared, all in one place. It does not make much of a difference for the purpose of this article. Anyhow, here is the thought process behind each idea as expressed on our side. Go over each one of them and see which one matches your thoughts the best.
Preventing any counterplay on the king side
It would stop Kf2 from coming down.
Since we own the d-file their king would be trapped to the upper left quadrant, thus making a race of kings to the center a mute point. This would give us time to move our K/R/pawns where we like.

Bringing the king in the game
It is the most logical move centralizing our king and slowly and calmly improving our position.
We need to centralize the king and prevent counter-play. 26… Ke7 is clearly the only way to achieve both.
If our rook alone can cause trouble, just imagine if we get both our king and our rook working together.
Endgames are a matter of style. My preference is for eliminating any counterplay the opposition might have. Why take chances when we are ahead?
Moving the king to the queen side is to seek attacking those isolated a- and c- pawns. Think about it this way: if our king forces their rook to defend those pawns, our rook can easily outplay their king. Yes, a centralized king is needed in the endgame; however IMO supporting our pawns and targeting their weak pawns is more appropriate in this position.

Going after the weak queen side pawns
I thought 26… Rd1 was the way to go to get the rook behind the pawns.
Right now, I like 26… Rd1 because I think that we can get either their h3 or a3 pawn. There is no risk with this maneuver. We can always centralize our king later.
I agree that 26… Ke7 is also good and will win eventually. I just think 26… Rd1 is a bit more accurate.
I should say that I know 26… Ke7 is the obvious positional move, and unless 26… Rd1 outright wins material we should centralize the king.
In the lines I’m seeing, 26… Rd1 does win a pawn and keeps their king close to their h-pawn as a bonus.

Using the 5th rank to swing the rook on either side as needed
I would firstly like to be able to swing the rook over and the fifth rank is where this can happen. Secondly, I believe our king must seek the maximum of central activity and that there is no reason to bury him on the queen side, where our two pawns are never ever going to break through alone whereas after trading the h-pawn, our sound three connect pawns will give us a lot of opportunities against their weak king side pawns.
I prefer 26… Rd5 and rather than bringing the Black king to the queen side, I was hoping for it to play a more central role.

Each of the above have merits more or less. It is a matter of style and endgame knowledge which one to choose and play. Probably all of them lead Black to winning, so which one seems the most attractive to you? In the end our team chose to bring the King in the game and used it to win a second pawn on the queen side; once that happened, our passer on the queen side became a decoy and enabled our king to penetrate on the king side. It is interesting to note how we used the rook to hold the fort and that eliminated any possible counter play. White had no chance to create trouble with our 7th rank protected. Yes, the endgame continued for 18 moves and some might find that too long. We simply believe (and there’s more of us after such games) it is a pleasure to play won positions on the winning side for as long as it takes. What do you believe?

The Wrong Rook (2)

“We are our choices”
Jean-Paul Sartre

More than a year ago I wrote an article on the same subject. You can review it here and that could help you figure out the solution to this puzzle as well.


You could say “But this one has 2 extra pawns in it”, so let’s look into why those pawns are on the board. The position has equal material. Re3, Re2 and Rb3 are in a standoff, all being under attack one way or another. An exchange leads to a simple draw since both pawns can either do damage or be captured as shown. In the same time Black’s rook battery along the 3rd rank protects its king from being checkmated and keeps an eye on the f6-pawn.

You might get the feeling in the beginning those pawns are important. Both of them are passed and on the 6th rank. The White king is not in the a3-pawn square, while the Black king is in the f6-pawn square (please review lesson 26, level 3 of our app). The a3-pawn cannot advance at the moment; the f6-pawn can and Black could catch it by moving either the rook or its king. If Black wants to catch it with its rook (1. f7 Rf3), it has to consider Rb3 is under attack and would be lost. That means the only move it really has is 1. f7 Kg7 Next we should look at what White can do about its pawn. Defending it 1. f7 Kg7 2. Rf2 Kf8 leads nowhere fast, so what about promoting it?


Now we have reached a similar situation with the other puzzle. White has sacrificed its pawn and all it has left is to attack the king. Should it do it with 1. Rf2+ …, 1. Rf1+ … or it does not matter? If the king goes toward the h8-corner, White wins no matter what because like in the other puzzle Black loses a rook. We also see in the process why the a3-pawn is needed, as the White king uses it to hide from checks (see line A). Now we look at what happens if the Black king goes in the center and we could observe quickly the difference between having a rook on e2 or not (see line B). Going back to the main line, we conclude it matters which rook is used to check with; one move leads to a draw and the other one to a win. Hope you have enjoyed it.

Inexplicable Endgame Play

“If you are weak in the endgame, you must spend more time analyzing studies; in your training games you must aim at transposing to endgames, which will help you to acquire the requisite experience”
Mikhail Botvinnik

This week’s endgame comes from a voting match we played as part of one Canadian team during an 8 months period. The team componence (46 players for us versus 6 players for them) seemed to favor us by quite a bit, still getting things organized as a team with so many players is not easy to do. We are getting better at it as time goes on. We have far less “drive-by” players (those who just vote for any move they think of, even moves never discussed) and we have managed to prove to our regular team members that discussing our options before we start voting actually pays off. In this particular game we managed to overcome a so-so opening and shaky middle game play into the following endgame position (White to move):

The general consensus here was that despite the extra pawn, we had no chance to win at correct play. I was one of the members interested to offer a draw, but the team decided to play on. It turned out to be a very interesting experience. Do you agree the position should lead to a draw at correct play? Here are a few reasons for it:

  • The extra pawn is doubled and even if they are center pawns, as long as they stay doubled they are of little use
  • The double rook endgames are far more tactical because of the existing fire power and both kings need to be protected
  • The important h4/h5 pawn moves have already been played, establishing clear boundaries on what those pawns can do
  • White’s plan should be very simple here: take control of the 2nd rank and put pressure on the e5-pawn with both rooks to impede its advancement

Instead of the above White chose firstly to bring his rook onto the 7th rank. Of course an (un)written rule says the best position for any rook is on the 7th rank. We actually have the opportunity to see how any of these rules cannot be applied without making sure the situation on the chessboard warrant them.

The above mistake was important but not decisive. Letting us take control of the 2nd rank, the same idea they tried at the wrong time, made absolutely no sense. That also meant we now had a clear path toward winning. Some may say this second mistake allowed us to win it; in reality they were both connected. The remaining of the endgame was more or less technical. Enjoy the winning line and hope you will learn a bit from it. You never know when your opponents might offer you the opportunity to punish their endgame mistakes in inexplicable fashion.

“What Say You?” The 1 Minute Challenge (4)

“A wise man can learn more from a foolish question than a fool can learn from a wise answer”
Bruce Lee

A quick reminder about how to do it:

  • Have a look at the position for 1 minute (watch the clock)
  • Think about the choices in front of you and pick the one you feel it is right
  • Verify it in your mind the best you can
  • Compare it with the solution

Are you ready? Below is this week’s position asking you to choose the next move for White. What is the most likely result based on your choices?

Here are my thoughts:

  • Material is equal
  • Each side has a passed pawn and both kings are within reach (see rule of the square in our app level 3, lesson 26) with a plus for the Black king being closer
  • Pushing the pawn forward 1. c5 … gives Black time to activate its king (1… Ke6 for example). White will have to capture the a-pawn, while Black will do the same with the c-pawn; after those pawns come off the board, Black’s king will be closer to capture the g4-pawn and promote its remaining f6-pawn (see basic pawn endgames in our app level 2, lesson 19). Black could win in this case
  • Based on the above idea 1. Kd4 … does not look like a good idea either because it also allows 1… Ke6. The difference in this case might be the fact the White king stays close to its c4-passer, it could capture Black’s a-pawn and come back in time to defend the passer; hmm, this is an interesting thought after all
  • Continuing along this line of thought 1. Kd5 … looks the best since it is keeping Kf7 away. The problem here is that after 1… a4 there is no other response but the forced 2. Kd4 … or the a-pawn promotes. We are now back to the previous line with the a-pawn farther down the board. This will draw the White king away and allow the Black one to activate; after the simple moves 2… Ke6 3. Kc3 Ke5 4. Kb4 Kd4 there is nothing better for each side than pushing pawns down toward promotion and a draw
  • Going back to 1. Kd4 Ke6 and using the information gathered in the 1. Kd5 … line, this must be the move to play. The a5-pawn has not moved yet and black must choose between moving it or bringing its King closer; in both cases this is good news for white

Conclusion: 1. Kd4 … gives white the best practical chances and should be played. You might be out of time by now to be able to determine if white can win this or not. The endgame has one more nice wrinkle white must consider in order to win and you can see it looking at the solution below:

What can we conclude out of it? Sometimes we might have to go ahead and play the most promising line even if we don’t see the final result for various reasons. We must keep our focus and apply our thought process along the way to uncover opportunities and achieve the best possible result. Start with the simple stuff first and build on it based on your knowledge; wherever your knowledge stops, mark it down and make sure you focus on expanding it during your home preparation. Good luck!

“A wise man can learn more from a foolish question than a fool can learn from a wise answer”
Bruce Lee

This article marks the 1 year anniversary since I joined Nigel and friends on this site. I am very grateful for the opportunity and would like to say:
“Thank you Nigel for bringing me on-board!”
In life we are presented with a finite number of opportunities. The twist each time is not knowing if they are the right ones, if it is the right time or simply if we are ready for it. In a way it is similar with what we face on the chessboard at every move and of course each one of us reacts differently. My approach is to take it if it feels right. Young people have a tendency of letting them pass, searching for that elusive once in a lifetime opportunity to certain success. One goes by, there will be several others coming our way, isn’t it? I was more or less the same, don’t think for a second I was not. John Snow’s words are true, don’t you think?
Theon Greyjoy “… Remember we were all young and stupid, you always knew. Every step you take is always the right step.
John Snow “It’s not. It may seem that way from the outside but I promise you it’s not true. I’ve done plenty of things that I regret…
We simply don’t know which opportunity leads to certain success and this, I argue, is the whole point of life: choose what you feel is right for you at any given moment.

I had and still have no idea where this opportunity is going to take me. I tried my writing several times in the past with more or less success and realized I liked doing it. That was helpful in deciding to take it. The weekly format forced me to adjust on the fly and look for subjects of interest on a regular basis. I had no idea this was going to happen when I made my decision. Life has a lot of twists and turns. The decisions we make lead us in different directions. The final destination might be there waiting for us no matter which way we choose and of course it is still possible we might not reach it in the end. The best we can do is give it our best shot each time.

Right now I feel this 1 minute challenge idea has value for many. In a World full of opportunities and an overwhelming amount of information at our fingertips, thinking for ourselves and making the best possible decisions is increasingly important. No engine or similar tool will help you do that. They are just tools. Yes, an engine will “show” you in a split second the possible result of a move/ decision; however it will never be able to “explain” it to you. That is what really matters and why we should continue practicing it. A quick reminder about how to do it:

  • Have a look at the position for 1 minute (watch the clock)
  • Think about the choices in front of you and pick the one you feel it is right
  • Verify it in your mind the best you can
  • Compare it with the solution

Are you ready? Below is this week’s position asking you to choose the winning move from the 4 options presented (in no particular order):

Here are my thoughts:

  • It is another endgame with White having considerable material advantage
  • The White king is too far away so 1. Kg2 … or similar does not help. The rook and pawn must find a way to get it done
  • Sacrificing the rook in exchange for promoting the pawn 1. axb5 Kxa1 gives us a basic queen versus side pawn endgame (lesson 17, level 2 of our chess app); with the White king so far away, this position is a draw
  • Moving the rook decision brings a new twist: where should we move it?
  • Moving it to the king side (as far away from the king as possible) 1. Rg1 bxa4 loses the pawn and reaches a rook versus pawn endgame (lesson 18, level 2 of our chess app); with the White king so far away, this position is also a draw
  • The remaining choice 1. Ra3 Kxa3 2. axb5 … is kind of out of the box thinking, don’t you think? The main idea is to force the king in front of the a5-pawn and away from the a1 promotion square. This would allow us to promote with check and win sufficient tempi to capture the remaining pawn and win the game
  • One last detail is to go with your gut feeling in the line 1. Ra3 b4 It is possible you might be out of time by now. All you would need to calculate is if you have enough time to capture the a5-pawn and stop the b-pawn from promoting

Here is the solution:

I found the position interesting and educative. The answer was not obvious and reaching it required solid knowledge of basic endgames, plus a well thought plan. If some might think this puzzle is too easy, do not dismiss it. You can use this one or similar to warm up during home preparation; do not start with the tough ones first. Practice makes it perfect. Hope you found it useful.

The Mongolian Tactic

“I will not return alive if I do not defeat the Jin army!”
General Muqali

I had the chance to watch live online the game between Anand and Carlsen, Sinquefield Cup, 04-Aug-2017 (full game HERE). At the end of it GM Yasser Seirawan made an interesting comment about Anand’s choice to draw the rook and pawns ending they were playing. He said the pawn push 60. g4 … was called “the Mongolian tactic” and he knew about it from a game played or witnessed by Fischer many years ago. Apparently Fischer was the first one to name it as such (or possibly “the Mongoloid tactic”). I have never heard of it before and Yasser’s comments made me extremely curious. The truth is Anand’s choice settled the game quickly, proving its effectiveness. Here is the final part of that endgame:

It could be that time in my life when studying history and bringing back into the spotlight useful information is important; another possible reason is I first fell in love with the antiquity and the first profession I thought about pursuing was archeology. Right after the game I started doing some online research with the intention of writing this article; as you can see it took me almost a month and have still not been able to find more than what you can see here. Apparently Yasser wrote an online article for “The Kibitzer” column @ The Chess Cafe website in the early 2000 (2003 or 2004?), but I could not find it anymore. What I could find though were a couple of games where “the Mongolian tactic” has been used before. The first game between Carlsen versus Yue (full game HERE) also contains a few interesting comments by a couple of users about the history of its name. Thank you “TugasKamagong” and “Shams” for sharing your knowledge!

  • TugasKamagong: “Carlsen’s 46. g4 … is a pawn maneuver that doesn’t have a name. <Shams>, posting in the tournament kibitz page King’s Tournament (2010) a few minutes after that move was played, called it “the Mongolian tactic.” I can’t find a game where a Mongolian player made this maneuver, so I guess <Shams> was alluding to some brilliant 13th-century war tactic by Genghis Khan at say, the Battle of Badger Pass. Anyway, I propose that we use <Sham>’s term and call this the Mongolian Tactic or perhaps the Mongolian Break-through…”
  • Shams: “Yes, who can forget the carnage that day at Badger Pass. I had thought Fischer used the term “Mongolian tactic” for this? Not sure where I read that.”

Here is the final part of that game where “the Mongolian tactic” brought Carlsen a full point:

“Shams” and user “Anastasia” also made a few comments about it for a game between Polgar and Almasi (full game HERE)

  • Shams: “72… g5 allows 73. g4! … what Fischer used to call the “Mongolian Tactic” (don’t ask me why.)…”
  • Anastasia: “not to be picky but Fischer actually called it the mongoloid tactic”
  • Shams: “hmm, do you know the story? google isn’t helping. I’m curious…”

These users are additional sources confirming Yasser’s recollection of the name being linked to Fischer.
Here is the final part of that game where “the Mongolian tactic” also brought Judit the full point:

Here you have it now in one place. Could anyone shed a light on this very clever piece of tactics and help set the record straight? I think it would be nice to save it for future generations as part of other pieces of wisdom in the endgame. I would be more than happy to write more on the subject and even offer this space to anyone wishing to contribute to it; until that happens, I think we could all re-learn about it and have it ready in our daily endgames. Remember the pawn cluster g4-h4-g5-h5 whenever the kingside pawns face each other and because h2-h4 and h7-h5 are important and popular moves to play in the endgame, always ponder carefully the g3-g4 or g6-g5 pawn push in the light of “the Mongolian tactic”. It is pretty devastating!

A quick reminder about how to do it:

  • Have a look at the position for 1 minute (watch the clock)
  • Think about the choices in front of you and pick the one you feel it is right
  • Verify it in your mind the best you can
  • Compare it with the solution

Are you ready? Below is this week’s position:


This week’s challenge is a king and pawns endgame with Black being up by 1 pawn. Here are my thoughts:

  • There are no passed pawns
  • At first glance the Black king seems unable to defend its isolated pawns, so my first reaction was to try line A: 1. Kg3 … and after a few seconds I realized Black wins with ease
  • The second logical try is line B: 1. Kf1 … where White has the opposition. The concept of the opposition (level 2, lessons 19 of our app) is critical in such endgames and it offers simple yet powerful guidance toward a desired result. Surprisingly here it does not work because Black uses the position of the f3-pawn and after 1… Kd2 2. Kf2 Kd3 wins the opposition back, followed by the game
  • Three of the remaining choices (1. Kg1 … 1. Kh2 … and 1. Kh3 …) do not make much sense in my opinion

If you are still with me, you know there is one move left: 1. Kh1 … It seems counter intuitive for a human player. Why on Earth would I consider moving my king in the most unpleasant square available, away from the f3-pawn and far away from those Black pawns? I looked at the solution and couldn’t believe that it was the one, a move discarded by my intuition from the first moment… Of course once this happens, the normal reaction should be to figure out the reasoning. What do you notice first after you play 1. Kh1 …? If you have noticed White has the distant opposition, it is very possible you found the solution in time. Truly after the second try (1. Kf1 …) you should be looking at 1. Kh1 … instead of discarding it. The distant opposition might not come into play as often as the opposition; however it is as important and powerful. One other interesting observation: after 1. Kh1 … the position has a nice geometric motif: if you consider the f-file as a vertical axis of symmetry, the position is symmetrical.

Do not feel bad the engines spit out the solution immediately. You can look at it and replay it but do not stop there! Do the next step of figuring out why the solution is as it is based on your knowledge. The thought process involved is going to help you in future games and really this is what matters. Play your own games/ positions and don’t let the engines take that away from you regardless how “perfect” they play. Enjoy the full solution below:

Endgame play (5)

How do you feel about king and pawns endgames with equal number of pawns on the same side? Are you concerned and study them? Do you know them and believe they are simple to deal with? What do you think about the following classic endgame and how it got played out?

Do you think White is lost here anyway because of the better position of Kd5 and possible loss of the f5-pawn? Of course not being able to use the opposition to stop the opposing king from invading your position is a concern, the same is having unprotected pawns (like the f5-pawn) left behind by their adjacent friends. The key is to know all resources available in your position. Can you think about a resource Chigorin missed? White has no way to push forward, nor breakthrough to create a passed pawn. If it simply retreats (like it did in the game), it won’t even be able to think about holding a draw in a king versus king and pawn endgame for 2 reasons:

  • The Black king will be in front of its pawn(s) as it should
  • Black is going to be up minimum 2 pawns after winning the f- and h-pawns

Retreating is basically surrendering! The only chance is to look elsewhere and from the remaining options the only one making sense is stalemate. How do we force black to stalemate us? We need to find a good spot for our king and give black no options. A good spot we can reach is on the h-file, where the h5-square not only suits our idea but also blocks the h4-pawn in the same time. All you need now is care to put together the right move order:

Did you know about this stalemate idea? If you did, don’t forget it. If you did not, remember it as you never know when it can come in handy. Here are a couple of more recent examples where it paid off to know it. The first one is from a game played by well known top players:

The second one is from a recent game between 2000 to 2300 players:

I hope this article makes a good case for learning and perfecting the fine details of this endgame with pawns on the same side. It does not look like much when you go over it; however knowing it is essential and can bring you invaluable half points in your games.
