Recognising the Patterns : Challenge # 21


This is one of the key endgame patterns that you must know by heart. Silman called this position as “Cat N Mouse” position. I called it “Tom and Jerry” when explaining it to my students so they can remember it easily. In this position whoever has the move will lose. The pawns could be at any file or rank, of course you can’t achieve this position when the pawns are on the rook file.

Now try to solve following problems by recognizing the above pattern:

Hermann Voigt against Emanuel Lasker in 1892 – Black to Move


Q:Black is exchange up, find the quickest way to win this position.
A: Black can win this position by pinning the rook as follows:

80…Rc3

This achieves the Tom and Jerry position on next move by capturing the bishop.

81. Kg4 Rxf3 82. gxf3 Ke3

Achieving the desired position where white will lose the pawn and game by force.

Semen Khanin against Semen Dvoirys in 2014 – Black to Move

Q: In the above position Black played 31…d5 to try to deprive a5 square from Black’s rook. How would you evaluate it?
A: 31…d5 is a blunder while with 31…Kd6 Black would have had better chances to hold the position despite losing the a6 pawn.

31…d5?? 32. g5 Kd6

If 32…Kd7 then 33. Rxf6 wins

33. Rxf6+ Rxf6 34. gxf6 Ke6 35. Ke3 – Kxf6

Despite the material balance Black’s position is hopeless.

36. Kd4 Ke6 37. Kc5 Ke5 38. d4 Ke4

White has achieved the desired position but he must be careful

39. a3!

And not a4 which in fact is winning for black. But after a3 white went on win in few moves.
