Hanging Pieces

This article aims at beginners only. When we talk about hanging pieces or pawns, the general understanding is that a piece without support is called a hanging piece. I would like to propose a different categorization, and one which can significantly reduce the number of blunders by just observing and understanding them.

I largely divide hanging pieces into two categories:

A) Pieces that have no support or can have their support removed:
Pieces that have no support, or can have their support removed, are technically undefended. With pieces that are supported like this the attacker always just remove the support and then they are just like undefended pieces.

Position A:
This is a variation from the game Miguel Najdorf vs Robert James Fischer, 1966 (White to move)


This is very simple, Qc8 check wins the rook on b7.

Position B)
Miguel Najdorf vs Robert James Fischer, 1966 (White to move)


This is the same scenario as White can first play Nxd6. In the game Fischer resigned in view of Qxd6 and now Nxb7 and we achieved position A in case of Rxb7. Of course Black can’t trap the knight with Qb6 or c7 because of pawn to d6.

B) Pieces performing crucial tasks are always hanging:
Here the piece is performing or going to perform a crucial defending role. It is therefore always hanging no matter how many times it is defended. The game is usually over once it has been captured.

Here’s a position I composed myself:


Here the bishop on c5 is defended three times but this bishop is going to perform the very important task of preventing checkmate vai Qh6. So this bishop is hanging no matter how many times it is defended. White can win the game with Rxc5.

Tiny Pawn Weaknesses

When your opponent is controlling the open file, we automatically go for trade of rooks if possible. Here is a position in which White did this.

Erich Cohn vs Akiba Rubinstein, 1909

At first glance it seems that White is perfectly OK as there is no way for Black to create any passed pawn in spite of White’s doubled pawns on f file. Can you see any hole in White’s position? Actually White’s doubled pawn weakness can be exploited in the king and pawn endgame. Rubinstein’s play is really instructive from here:

In the following game Kasparov played 9 d6. Although this does not win material directly it fixes the pawn on d7 and therefore creates huge problems for Black in development. The rest of the game seems technical:

Knowing The Opponent’s Plan

This article is aimed at beginners only. Almost at all levels of chess, players try tricks to trap their opponents, the only difference being the level of difficulty. So when do you have better chances of making a fool out of your opponent? The simplest answer is when you know their plan.

Here is a nice miniature to show you the importance of knowing opponent’s plan in order to create a successful trap.

Practical Chess Endgames for Beginners

This article is aimed at beginners, to show them why they should study andlearn endgames. Here is my game from the current tournament where my last move was Re6 to win a pawn.


My opponent was rated 1482 and played opening and middle-game really well, but finally I got a chance to win a pawn. How would you continue from here? Which pawn will you save, b6 or h6?

In the game he played b5 and I went on win due to the following reasons.
1. My rook is more active than his as it is behind his passer.
2. I have a chance to create two connected passed pawns on the kingside.

Instead he should have played Kg7(!), protecting the h6 pawn after which Rxb6 is a draw. He was perfectly aware of the Lucena and Philidor positions, however he was not aware that there are more chances where these 3 vs 2 pawn positions can lead to a Philidor position. That is why I always insist that learning positions is not enough on its own. You should repeat them on regular intervals and also learn how to achieve them. In practice you won’t get book positions very often.

The game was not easy even after …b5 and Rxh6. Here is the analysis:

Sicilian Dragon : A Model Game for Beginners in the Yugoslav Attack

In my last article I tried to describe White’s plan to destroy Black’s king side in detail. Here I will annotate the game in detail which I believe, can be served as a model game for this.

Sicilian Dragon: The Yugoslav Attack

This article aims at beginners and intermediate players to provide basic strategy to play against Sicilian Dragon. The most dangerous attacking setup against Sicilian Dragon is the Yugoslav Attack where White’s plan is fairly simple but nonetheless very strong.

Strategy:

1. White’s light square bishop usually exchange the Black’s knight on c4 (the knight attacks the queen on d2 and bishop on e3), otherwise that bishop will have great potential on the a2-g8 diagonal (refer to Fischer vs. Larsen – sac sac and mate).

2. White is aiming to exchange the dark-square bishop on h6. And in the absence of his dark square bishop the safety of Black’s king can be compromised.

3. White will open the h-file with the h2-h4-h5 thrust.

4. Lastly White will try to remove the knight from f6 in order to deliver checkmate along the h file and probably h7 or h8.

Caution:

Black’s main counter play is heavily reliant on the counter attack along the c- file and a1-h8 diagonal. Here is a game which I believe, covers the above mentioned points and can be served as model game to beginners.

On my next article I will present this game with more notes. Meanwhile the reader is invited to figure out what was going on.

Recognise the Pattern # 37

This article aims at beginners only. Here are some positions on a typical theme. You are advised to find the solutions first and then look at the theme name and the solutions:

1. Bill Wall vs Robert Gantt 1978
White to Play

2. Eduard Hamlisch vs NN 1899
White to Play

3. Shmatkov vs Eidlin 1960
White to Play

The theme is ‘sacrifices on f7/f2 against uncastled king’. Of course the main idea is to keep the opponent’s king in the center but often it is used to win/trap opponent’s queen in conjunction with mating threats. I thought I have covered this with my series on recognising the pattern, but it was missed out. Recognising the pattern is a series where I have discussed typical checkmate patterns, attacking formations and endgame patterns.

Solutions

Solution 1:

1.Bxf7+ Kxf72.Ng5+

Black resigned in view of Ne6 in case of Kf8 or e8 and Qc4+ in case of Kg8.

Solution 2:

1.Bxf7+ Kxf7 2.Ng5+

Black resigned in view of Ne6 in case of Ke8 whilst Kf6 can be met by Qf3#.

Solution 3:

1.Bxf7 Kxf7
2.Ng5+ Kg6

If 2… Kf8/e8 then Ne6 wins the queen or if 2…Kg8 then Qb3 wins.

3.Qd3+ Kh5

If Kh6 then Ne6 discovered check wins queen.

4.Ne6

This wins due to the threat of winning the queen or checkmate with Qh3.

From Middlegame to Endgame

Kashdan vs Alekhine 1933, Black to Move

No great chess player complicates matters unless they find a simple solution. Alekhine was not an exception, White’s last move was Nb5 attacking the c7 pawn. Alekhine used little tactics to reach an endgame where his knight and passed pawn on the g-file are simply enough to win the game.

Here is the solution and the rest of the game.

Simplification

Simplification in chess can be a decisive strategy, and one that is much deeper than generally understood. Here are a few examples which illustrate when you can employ this strategy:

1) Simplification to dissolve an attack (Example by Fred Reinfeld)

Here Black has material advantage but his rook on d8 is attacked. If it moves the bishop on d7 will fall. So how would you continue from here?

The solution is as follows:

1…Qxd1!! 2. Qxd1 Bg4!

Black can keep his material advantage and White’s attack is just gone.

2) Simplification for piece activity (Vassily Smyslov vs Milan Vidmar in 1946)

Here Smyslov went for simplification in order to bring his rook on the 7th rank and went on win after a few more moves.

1.Qxg7 Kxg7 2.Bf4 h6 3.Nd2! g5 4.Bxd6 cxd6 5.Nc4 d5 6.Nd6 Rxe1+ 7.Rxe1 Kf6
8.Nxf5 Kxf5 9.Re7!

White’s rook is much more active than its counterpart and he went on to win.

3) Simplification to hinder the opponent’s development ( Wilhelm Steinitz vs Bardeleben in 1895)

Here Steinitz went for 3 minor piece exchanges and caught the Black king in the center. This temporarily prevented Black from connecting his rooks and when he did manage to connect them it was too late. For the solution just go through the game.

4) Simplification to reach a winning king and pawn endgame (Kasparov vs Milan Vukic in 1980)

Here Black’s last move was Nf6, yet this innocent looking move is a decisive mistake. Can you simplify the position to reach winning king and pawn endgame?

Solution:–

1.Bxf6 gxf6 2.Rd1

Black resigned in view of 2…Rxd1 3.Kxd1 followed by g4-g5 clears the way for the h5 pawn to march forward.

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.
