PRACTICAL CHESS ENDGAME 20/2/2000

Welcome to this active site. Each week I am going to present to you a endgame position for you to solve or to workout the best continuation. Computer analysis will also be considered. Some of these positions will come from actual historical games. Others will be composed endgame studies, but all the solutions will be relevant to the practical game.

The new position will occur each SUNDAY and I will always be pleased to receive POSITIVE feedback about the positions and the analysis and I will try to acknowledge these where relevant.

EG, 1969

White to play & WIN 

 

FORSYTH NOTATION:8/8/8/p1N5/2Kp4/P2P4/1p6/1k6:

Black is threatening to queen the b-pawn in two moves. The only way White can meet this threat is to offer the sacrifice of the Knight for the b-pawn and hopefully to reach a won K&P ending. A feature of this charming study is the way the Knight, operating from the edge of the board, copes with the Black pawns.

1.Na4 ....

1.Nb3? Kc2 2.Nxd4+ Kd2 3.Nb3+ Ke3-+ the b-pawn cannot be stopped from queening.

1...Ka2

2.Nxb2 Kxa3!

Black creates a passed pawn. Capturing the Knight leads to a won Queen ending for White: 2...Kxb2 3.a4! (3.Kxd4 Kxa3 leads only to a draw)3... Ka3 4.Kxd4 Kb4 (4...Kxa4 5.Kc4 Ka3 6.d4 a4 7.d5 Kb2 8.d6 a3 9.d7 a2 10.d=Q a=Q 11.Qd2+ Wins) 5.Kd5 Kxa4 6.Kc4 Ka3 7.d4 a4 8.d5 Kb2 9.d6 a3 10.d7 a2 11.d8=Q a1=Q 12.Qd2+ Ka3 (12...Kb1 13.Kb3! ) 13.Qb4+ Ka2 14.Qb3#

3.Nd1 a4

4.Kc5!...

This is the only move to win.

Not 4.Kxd4? Kb3 5.Nc3 a3 6.Ne2 Kb2 7.Nc3 Kb3= ;

or 4.Kd5? Kb4 5.Kxd4 a3 6.Nc3 Kb3= ;

4.Nf2? Kb2 5.Ne4 a3 6.Nc5 a2 7.Nb3 Ka3 8.Nxd4 a1N!=

4.... Kb3

White wins after 4...Ka2 5.Kb4 a3 6.Ka4 and Black can no longer guard the a-pawn.

5.Kxd4 a3

6.Nc3 ...

A position of reciprocal zugswang. If it was White's turn to move, he could only play 6.Ne2 and Black draws by replying 6...Kb2 7.Nc3 Kb3 8.Ne2 etc, leading to a threefold repetition. But it is Black to move and he has no saving variation.

6.... Kb4

7.Na2+ Kb3

8.Nc1+ ...

What a wonderful Knight!; it now stops the a-pawn from advancing.

8...Kb4

Or 8...Kb2 9.Kc4 Kxc1 10.Kb3 Wins.

9.Kd5 Kc3

10.d4 Kb4

11.Kc6. Kc3

12.Kc5 Kb2

13.Kb4!...

Black is lost. He cannot stop the progress of the d-pawn. The Knight stays on c1 and can never be captured because the a-pawn will fall.
