Rook and Pawn vs Two Knights or Bishop and Knight

There are many games with this material imbalance, so it is important to know the basic strategy in such situations. Broadly speaking we can divide into two parts, middle game strategy and endgame strategy.

In the middle game two minor pieces tend to be stronger than the rook and pawn as the rook won’t be able to find open lines. Therefore in the middle game player with two minor pieces should attack with his extra piece, as in the following instructive example.

On the other hand the player with the rook and pawn should look for an endgame where his opponent does not have a single major piece on the board. In such cases the availability of a passed pawn and targets matters a lot and if the rook is able to access the targets it can often win. Here are a few examples:

A) Rook and pawn vs. two knights but the rook fails to find targets


B) Rook and pawn vs. two knights – the rook wins

Here all Black’s pawns are weak and so White’s rook can target them easily:

C) Rook and pawn vs. bishop and knight – the rook can’t find a target

D) Rook and pawn vs. bishop and knight – the rook wins

There are of course exceptions to these situations, but generally speaking the rook and pawn are better in endgames.

ChessJournal App

“Record, analyse and store your competitive ‘over-the-board’ games”

This week I am happy for the opportunity to present another app useful for the club player, app called ChessJournal. It is created by Jon Fischer and Matt Lawson both from Bristol, England and it can be downloaded for free at the iTunes and Google Play stores. Jon was kind enough to help me write this article by answering to a few questions. Hope you like it and will decide to give this app a try!

Eugen: A short introduction about you and your team
Jon: ChessJournal App is a passion project started by a chess addicted designer and a chess intrigued developer! Me and Matt both work in the digital design sector and are passionate about product design best practice. Also we are both young fathers and are thus very short on time! When you combine our first two passions with a shortage of time to study, ChessJournal App is the logical outcome! We sat down together and asked ourselves, could we use an app to help club and tournament players study more, learning about their own games in the process?

Eugen: What is your chess story?
Jon: I have been playing chess since I was five years old and hover around the 1800 ELO (145 – 150 ECF). Matt knows the moves and would like to improve but probably needs a better coach than me!

I’ve been an avid club and tournament player in the Bristol and District chess league (in the UK) since 2004. Like a lot of adults I have noticed minimal change in my chess performances over the last decade. Every year the grades come out, every year I’m 145 ECF. Last year I decided to put down my openings books and started seriously studying my own games and nothing else.

  • No openings
  • No ending study or puzzles
  • No tactics trainers
  • Just me and my games

This year (using ChessJournal App) I have achieved my highest ever rating performance of 159 ECF (1892 ELO). An improvement of 98 ELO. Anecdotally I have had feedback from ChessJournal users that they have seen improvements between 65 and 110 ELO points. Obviously I don’t have any hard data on these numbers yet, but the anecdotal feedback is encouraging!

Eugen: Why this app? How did the idea for it come about?
Jon: The concept of ChessJournal started from a love of club and tournament chess and a feeling that the majority of apps didn’t really help amateur players improve. As I browsed through the app store, I felt the majority of apps fell into one of four camps:

  • Play other humans at blitz
  • Tactics trainers
  • A chess database of master games on your phone
  • All of the above!

My problem with a lot of the apps on the market was they either focused on openings, puzzles, master games or five minute blitz. But the majority of chess coaches and masters agree that one of the best ways to improve is through studying your own games and learning where you personally make mistakes. Whilst I love a cracking game of online blitz as much as the next player, it isn’t really helping me make better decisions, learn from my mistakes or understand how my games are won or lost.

Funnily enough, around the same time I happened to read an article on the chess improver blog on the benefit of keeping a journal for the ambitious amateur. As I was reading the article I also happened to be staring at a shoebox of paper scoresheets from my regular attendance at local tournaments.

Thus me and Matt settled on the idea of a “chess players diary” that would enable amateur players to carry and study their own games wherever they go.

We started work on ChessJournal in January 2016 and launched version 1.0 in May last year. We run a lean iterative design and development approach meaning we are always looking for feedback from chess players and factoring in their thoughts as we push to develop the best chess players diary and scorebook available. We learnt an awful lot about what players need from a chess diary in v1.0 that we decided to go back to the drawing board late last year and rebuild the app from scratch.

We officially relaunched ChessJournal v2.0 on April 19th 2017 on both Apple and Android featuring a host of new powerful features such as cloud storage and the ability to set and track personal improvement goals across your competitive chess season.

So far the feedback has been fantastic! We are averaging 4 star reviews and above and we are receiving a lot of lovely emails (and new feature requests) from club and tournament chess players around the world. We have already planned and scheduled the next update for ChessJournal 2.1 and there are more exciting plans in the future.

Eugen: Can it compete with the big and popular guys such as Chessbase, Monroi, etc?
Jon: My initial response is that we don’t want to, or feel we need to, compete with the big and popular guys such as Chessbase. We genuinely take it as a compliment that ChessJournal is regularly used in the same breath as Chessbase!

There are similarities such as the storage and analysis of your own games but after that our focus on self study and goal tracking hopefully helps club and tournament players see the angle and approach that we are taking. ChessJournal is categorically not a database app. If you want to understand the 18th line of a sub variation of the Berlin defence then ChessJournal is not for you. We will never add a five million game database to ChessJournal.

However, if you are a sub 2100 player and serious about cutting out the mistakes, having easy access to your games anytime and easily sharing your annotated thoughts with your club mates and coaches then we feel you will get real value from ChessJournal. ChessJournal is all about your game and no one elses!

I grow tired of hearing 1650 rated players (and I include my former chess playing self in this category) debate the merits of opening lines and their theoretical soundness. The large software players in the market dominate at the elite and very strong club player level where, I agree, that you need to understand theoretical novelties and what different people have played.

I guess what me and Matt are saying is that we believe real chess improvement for the amateur player can come from a focus on your own games and therefore a piece of giant database software is perhaps overkill for a lot of players. But then thats just our opinion…

Eugen: What’s it competitive advantage?
Jon: Its free! Ha ha, seriously I genuinely feel that ChessJournal is excellent value! The app is free to download but to unlock all features (such as annotations and sharing of annotated games) we charge a modest annual subscription fee of £5 / $6 / €6 a year.

A second major advantage is that it is available on both major platforms, Apple and Google Android. We get a lot of positive comments from iPhone carrying club players grateful for the ability to store their games. Because it is cloud based your games can be accessed anywhere on any device. One of my best friends has an Android smart phone and an iPad but his personal ChessJournal is always the same, wherever he is.

The third major advantage is simply mobility. Because it is an app you can leave your laptop at home next time you attend that weekend tournament. We have built in full import and export features for PGN so that a player can input their games when they are at matches or tournaments and still export them to other well known popular chess database software.

Eugen: The app’s best feature is?
Jon: Personally I would say either the goals section of the app or the annotation timelines.

Goals allows a player to create unique targets and goals for their desired improvement across the chess season. They can literally make a goal anything they want but once created they can link important games to them as they move through the season.

The annotation timeline is a feature unlocked with premium membership where a player can create and save variations in the game and annotate key positions. I suppose I am just really pleased with the design of this area in the app and we are in the process of rolling out some even better user interface updates.

We have a solid roadmap of new features coming and are regularly receiving new ideas from the chess community. To finish I would say that in the long term we are aiming to create the ultimate companion app for amateur club and tournament players. This is just the start!

Thank you for giving us this opportunity to talk to you about ChessJournal. More information can be found on chessjournalapp.com

Saving A Draw

White was very resourceful in this endgame and saved a draw from a desperate looking position starting with the ingenious 77.a6!. Good defence is just as important as good attacking play.

How Good is Your Endgame?

Many readers will be familiar with the popular magazine feature, known in various places as How Good is Your Chess? and Solitaire Chess, in which the reader is invited to predict the next move in a master game, and is awarded points for selecting good moves.

Some time ago I showed you a couple of lessons based on shorter and lower level games suitable for use at intermediate level (up to about 100 ECF/1500 Elo).

As part of the Chess for Heroes project, which I’ll come back to in more detail, quite possibly next week if nothing else interesting happens in my life in the meantime, I decided to produce a few lessons using king and pawn endings, with the games taken from the Richmond Junior Chess Club database.

Here’s the first one, which was tested successfully at RJCC the other day.

Set this position up on your board. At various points in the game you will be asked to select a move for either White or Black. Sometimes you will have three moves to choose from, and sometimes you will have a free choice. In this position it’s Black’s move.

If you find a winning move you’ll score up to 10 points. If you find a drawing move you’ll score up to 5 points. If you find a losing move or an illegal move you’ll score no points.

Choose a move for Black:
a) Kc6 b) Kd6 c) g5

10 points for Kd6 – head to the king side to attack White’s weak pawns
5 points for Kc6 – the wrong direction for the king
0 points for g5 – loses to an en passant capture

1… Kc6

Choose a move for White:
a) a4 b) f4 c) Kg3

5 points for Kg3 – get your king into play
0 points for a4 or f4 – creating targets for the black king

2. f4 Kd5
3. Kg3 g5 (Ke4 was one of many winning moves)

Choose a move for White (free choice)

10 points for hxg6 – a winning en passant capture
5 points for fxg5 or Kf3 – both these moves should draw
0 points for anything else

4. fxg5 fxg5
5. f4 gxf4+
6. Kxf4 Ke6

Choose a move for White:
a) a3 b) Ke4 c) Kg4

5 points for Ke4 – taking the opposition (a4 and b4 also draw)
0 points for a3 or Kg4 – both of these moves should lose

7. Kg4

Choose a move for Black:
a) b5 b) Kd5 c) Ke5

10 points for Ke5 – Black will be able to approach the white pawns
5 points for b5 – this should lead to a draw
0 point for Kd5 – this will lose after Kf5

7… b5

Choose a move for White:
a) a3 b) b4 c) Kf4

5 points for Kf4 – the only move to draw by keeping the black king from advancing too far
0 points for a3 and b4 – both these moves should lose
8. a3 a5 (Black had the same choice as on the last move. Again Ke5 was winning.)
9. b3 (Again, White had the same choice as on the last move. Kf4 was still a draw, as was b4.)

Choose a move for Black (free choice)

10 points for a4, b4 or Ke5 – all these moves should win
5 points for Kf6 – this move should lead to a draw
0 points for any other move

9… b4
10. axb4 axb4
11. Kf4

Choose a move for Black (free choice)

10 points for Kf6 – Black wins by taking the opposition
5 points for Kd5 – this leads to a race in which both players promote
0 points for other moves – White will win the h-pawn

11… Kf6
12. Kg4 Ke5
13. Kf3

Choose a move for Black (free choice)

10 points for Kf5 – taking the opposition
5 points for all other moves

13… Kd4

Choose a move for White (free choice)

5 points for Kf4 – leading to a drawn position with black queen against white pawn on h7
0 points for anything else

14. Ke2 Kc3
15. Kd1 Kxb3
16. Kc1

Choose a move for Black (free choice)

10 points for Ka2 – the quickest way to win
8 points for Ka3 or Kc3 – these moves are less efficient
5 points for Ka4 or Kc4 – both these moves lead to a draw

16… Ka3

Bonus question 1: what would you do if White played Kb1 here?
a) Ka4 b) Kb3 c) b3

10 points for Kb3 – winning by taking the opposition
5 points for Ka4 or b3 – both these moves lead to a draw

17. Kc2 b3+

Bonus question 2: what would you do if White played Kb1 here?
a) Ka4 b) Kb4 c) b2

10 points for b2 – winning as White has to play Kc2
5 points for Ka4 or Kb4 – both these moves draw as long as White plays correctly

18. Kc1

Choose a move for Black (free choice)

10 points for Ka2 – forcing promotion
5 points for other moves – all of which are only drawn

18… b2+
19. Kb1 and the game was eventually drawn

At the end of the exercise you’re assigned a Chess Hero rating:

95-120: Chess Superhero

70-94: Chess Hero

45-69: Trainee Hero

Below 45: Future Hero

If you teach chess at this level, please feel free to use this yourself. I may well decide to change the marking scheme in future, perhaps awarding 5 or 0 points rather than 10 or 5 in questions where there are only winning and drawing options: I’m still thinking about this.

The Comeback Trail, Part 13

I finally made my first tentative step back into competitive chess by playing the Rhyl Open last weekend. It made sense to choose this one as the scene for my comeback, it promised to be a nerve wracking experience and I wanted a tournament where I felt there wouldn’t be too much shadenfreude if I did as badly as I feared.

Having taken a half point bye on the Friday evening I managed to get a win and a draw on the Saturday. On the Sunday I was already feeling more confident and managed to win both games to finish first equal.

The key game was my Sunday morning encounter with Mike Surtees, a highly original player who does well in North West UK events. I had prepared for him the night before and I felt that his line against the Sicilian left Black with a promising position, similar to those White obtains against a dubious line of the Nimzo-Indian Defence. And in fact he found himself in a difficult position early on:

So where do things go from here? Well as my son Sam was good with us both playing (he did well with a win and three draws in the Major) I’ll be entering some more events where he’s playing. As for international events and stuff, they’re going to have to wait.

Active versus Passive Learning

When studyiing chess, an important element is not only the material you choose to study – whether it be a chess book, video, or software – but your level of engagement with the material. We can categorize learning (in general) into two types – active and passive learning. Although there is some debate around this (which I won’t delve too much into), in general active learning is favored for knowledge retention and application.

Passive learning is generally what you do when you watch a chess video or listen to a lecture. I also think passive learning occurs when you blindly follow chess engine analysis (and some may not consider this learning at all). You are “receiving” the instruction from a source.

Active learning by contrast is as it sounds – the student is engaging with the material. This could include activities such as solving tactical problems, doing Solitaire Chess, or analyzing your chess games (without assistance). You are a participant in the creation of the learning process.

Although I think there is a place for passive learning – for example, with beginners who know nothing of chess or when learning a totally new opening – we should try to make our training and study more active. 

In the following video, I discuss three techniques you can use to be more actively engaged with the chess videos your watch.

Try these methods out next time you watch a chess video!

A Strategic Opening for Beginners: The Ruy Lopez Exchange

Rather than memorizing opening moves and copying what top players are playing nowadays, it’s really great for beginners to play simple strategic chess openings. In the Ruy Lopez Exchange (1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Bxc6) White exchanges his bishop against Black’s knight on c6 and then plays d2-d4, exchanging the d4 and e5 pawns.

That creates pawn islands where White has a pawn majority on king side ( 4 vs. 3). On the other side, Black’s pawn majority won’t easily be able to create passed pawn, at least not without the aid of pieces. White’s strategy is very simple yet can be decisive. All you need to do is trade off pieces and reach to the king and pawn endgame where White is technically a pawn up and winning is relatively easy.

Here is the game for you to study, for more games on similar structure you can visit chessgames.com

A Poisoned Pawn

“… The notorious Poisoned Pawn arises after 6. Bg5 e6 7. f4 Qb6, with current theory suggests that the b2 pawn is not too heavily laced with arsenic, but it would be suicidal to enter the line without specialist knowledge.”
Graham Burgess, The Mammoth Book of Chess, 2000 edition, pg. 176

Fischer’s love for this controversial Sicilian Najdorf line is legendary. He was not just a “specialist” but the “guru” of it. People understood that fast and followed their newly discovered guru by playing it often; that is how an opening line becomes popular and players of all levels try to become immortals by finding the next refutation or proof of its validity. The engines have changed the game a lot and one critical aspect is proving a lot of gambits wrong; however a handful of them are still tough to crack and Najdorf, the poisoned pawn is one of them.

Back in 2014 I tried my first Najdorf, poisoned pawn as Black in a correspondence game and we drew it in 25 moves by perpetual and without any novelties or deviations. The chosen line was so well analysed, it made no sense for either of us to deviate and hope to get anything out of it. Today’s game followed a well analysed line as well; what is impressive about it is the surgical positional precision white used to win the game. It is a game played in the ICCF teams Olympiad Final 19th edition, the last edition played by post; a number of games are played by email, but each board (teams consist of 4 players each) has 3-4 players insisting to stick with playing by post as intended. The current standings for the final from where you can also see the situation on each board, can be seen HERE

Have you also been impressed with the positional play by ICCF GM Rufenacht? I think it puts this line under a strong question mark and it does not stop just there; the computer won’t be able to help you a lot if you need assistance. Black did extensive research to get out of the maze and it did not find the Ariadne’s thread; maybe you will but be prepared for a long road ahead. Of course if you find it, it will be published in the following Informator. Please don’t forget to mention who launched you down this quest though; good luck!… If you have any games and/ or positions you would like me to look at, please do not hesitate to let me know. I will gladly include them in my column for everyone’s benefit. Looking forward to your messages!

Connected Passed Pawns

A few weeks ago I posted this endgame win by Kopylov over Botvinnik using connected passed pawns. In the Rhyl congress yesterday I did something similar, getting some powerful passed pawns that were much stronger than my opponent’s. His piece sacrifice seemed a bit desperate but the engine confirms that Black is winning anyway:

Who Wants To Be A Millionaire?

Hans Renette, in his biography of Henry Bird which I reviewed last week, reports that, on about 1 June 1874, three weeks before Staunton’s death, Staunton, Bird and Ignaz Kolisch discussed the Sicilian Defence over dinner.

“Ignaz who?”, you might ask if you’re not familiar with 19th century chess history. There’s another relatively new (2015) McFarland chess history book that will tell you all you need to know: Ignaz Kolisch The Life and Chess Games, by Fabrizio Zavatarelli.

Kolisch was a stronger player than Bird, and, from the limited information we have available, seems to have been one of the best players in the world in the mid to late 1860s. He was born on 6 April 1837 in what was then Pressburg, a city belonging to the Kingdom of Hungary. Now we call it Bratislava, the capital of Slovakia. In 1845 his family moved to Vienna, and young Ignaz soon learnt the moves of chess

He first came to the attention of the chess public in 1857, winning a match against Eduard Jenay, one of the leading Viennese players of the day. He travelled to Italy, then to France, where he drew a match against Adolf Anderssen, and then to England, where he played in two small knock-out tournaments run by the British Chess Association. In Cambridge in 1860 he beat the American Charles Stanley in the final. The following year in Bristol he was knocked out by the only other strong player in the competition, Louis Paulsen, in the first round. He spent much of the autumn playing a match against the same opponent. Paulsen won 7 games, Kolisch won 6, with no less than 18 draws, a remarkable number for the time.

At some point in the early 1860s Kolisch decided to cut back on his chess and enter the world of finance. By 1867 he was living in Paris, where an international tournament was taking place. He went along to watch, but after the event had already started decided to enter. He eventually won first prize (5000 francs and a Sèvres vase, which he immediately sold), ahead of the newcomer Winawer and probably the two strongest active players at the time, Steinitz and Neumann. Gustav Neumann, by the way, is another forgotten name who deserves a modern reassessment.

Rod Edwards gives Kolisch a rating of 2700 at the end of 1867, behind only the inactive Morphy, so, although there’s not much evidence to go on, you could argue that Kolisch was, if only briefly, the strongest active player in the world at the time.

But that was the end of his competitive chess career. He devoted the rest of his life (he died on 30 April 1889) to his business interests, investing wisely and becoming extremely wealthy. He continued his interest in the Royal Game, becoming a generous chess sponsor.

Zavatarelli considers Kolisch the first truly ‘universal’ player, equally at home playing dashing gambits and brilliant sacrifices in odds and coffee-house games, as he was playing the more modern positional chess which he preferred in most of his more serious encounters. His brilliancies deserve to be as well-known as those of Morphy.

Just as with the Bird book, if you have any interest at all in 19th century chess history you’ll find this an essential purchase. The chess and historical research appears to be meticulous, and if Edward Winter is impressed with its accuracy I’m not going to argue. It might be churlish to point out a couple of things. One of Kolisch’s earliest opponents, Karl Mayerhofer, an opera singer who might be considered for the Musicians team in any future edition of The Complete Chess Addict, is described on p12 as both a bass and a tenor. In fact he was a bass-baritone. We’re also told that the Duke of Brunswick’s father (yes, the Duke played Kolisch as well as Morphy) was killed at the Battle of Waterloo. He actually died in the Battle of Quatre Bras, two days earlier, so my Almey cousins from Earl Shilton, about whom more at another time in another place, just missed seeing him die. Curmudgeon that I am, I’d be tempted to deduct half a star because Zavatarelli’s English, unlike Renette’s, is not entirely idiomatic.

Here’s a game from Paris 1867. White’s 36th move is a blunder. Contemporary sources give Bc3, Qc3 and Qe3 as improvements. The engines concur, giving all three moves as likely draws with best play.
