Recognising the Patterns: Challenge # 6

Today’s challenge is to find the typical pattern and react accordingly; White to move.

Grunfeld against Torre in 1925

Q:Black now played 11…Nxe5. Should White recapture on e5 directly or does he have a better option?

A: Capturing on e5 leads to resignation, which is what happened in the game.

12. dxe5?? Bc5+

13. Kh1 Nxg3+!!

Opening up the h-file followed by mate in two.

This typical pattern is similar to Anastasia’s checkmate where the knight covers the escape squares and rook or queen delivers checkmate via h or a file. Sometimes the knight’s role has been played by the bishop, and this is known as Greco’s mate.

Instead White should play 12.c5 first in order to cover the c5 square with his queen. For example:

12. c5 Nf7

The game is on, and note that Black can’t play a similar idea with 12…Be7 because of 13 dxe5 Bc5 14. Qxc5.

Nimzowitsch against Capablanca 1911, Black to move

Black’s position is clearly better but White’s next move, 32 b5, leads to quick finish. Use your knowledge of this and checkmate Nimzowitsch!

32…Rf6

Checkmate is now unavoidable.

33. Bxe4 Bf2!!

Nimzowitsch resigned here.

Janowski against Steinitz in 1898: Black to move

Black’s position is clearly better. The bishop on e3 covers g1 and if black manages to open up the h-file the game is over.

In the game Steinitz played:

32… Bg4

33. Qxg4 Qxg4

34. hxg4 Rh8+

35. Rh5 gxh5

White resigned.

Here knowing the pattern didn’t lead to checkmate but helped Black in gaining decisive material.
