PRACTICAL CHESS ENDGAME 04/03/2001

Editor: Brian Gosling

ALL RIGHTS RESERVED

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.

Thanks to Antonio Senatore, Alexander Vojna, Allan Bennett, Oliver Scalbert and Henrk Kalafut.
THIS WEEK

POSITION 181

White to play &DRAW

FORSYTH NOTATION:4K3/2k1Bp1N/6p1/5PP1/8/7p/b7/8:

LAST WEEK, POSITION 180

Max Euwe, (1901-1981).

World Champion 1935-37. Dutch Grandmaster. At the end of the 9th game of the 1935 World Championship Match Alekhine was leading by 6 points to 3. He looked set to keep his title but Euwe now had a brilliant run of games which completely transformed the match. He won the 10th, 12th and 14th and drew the 11th and 13th to level the score at 7 points each. The following endgame position is taken from this golden period in his career.

A. Alekhine vs M. Euwe

1935 World Championship

(13th Game)

Black to play & WIN

 

  FORSYTH NOTATION:8/P1R2p2/6k1/4K3/6p1/8/8/r7:

In this position Euwe missed the winning move ...Ra4! which cuts off the King along the rank from the important f4 square. In the game, Alekhine was able to draw after Euwe's 1...f6+? by playing his King in front of the passed pawns.

1... Ra4!

The 13th World Championship game continued: 1... f6+ 2.Kf4 Ra4+ 3.Kg3 f5 4.Kh4! (To stop the Black King from hiding when the checks of the Rook begin) Kf6 5. Rb7! Draw was agreed here since Black can't make progress.

2.Kd5! ...

The King goes to the queenside to exhange roles with the Rook so that it is free to tackle the pawns. This idea seems to offer the best defence rather than play 2.Rc4 f6+! 3.Kd6 Ra6+ 4.Kd5 Rxa7 5.Rxg4+ Kf5 which leads to a theoretically lost RPvR Ending.

2. Kd6 g3 3. Rc3 Rxa7 4.Rxg3+ Kf6 5. Rg2 Ra5 6. Rg1 Rg5 7.Rh1 Kf5 8. Kd5 f6 9. Rf1+ Kg6 --+ (Crafty 18.3 )

2... f6!

This move is important because it stops the King going back to e5.

2... f5 3. Ke5 Ra1 (3... f4 4.a8Q Rxa8 5. Kxf4=; 3... g3 4. Rc3 Ra5+ 5. Kf4 draw) 4. Kf4 Rf1+ 5. Ke5 Re1+ 6. Kf4 Re4+ 7. Kg3 Ra4 8. Kh4 Kf6 9. Rc6+ Ke5=;

2... g3 3. Rc3 Ra5+ 4. Ke4 f5+ 5. Kf3=.

3.Kc5 g3!

In Euwe' s book; From my Games 1920-1937, which is an excellent account of his early career, he gives "3... Kg5 and wins", but this move only draws: 4. Kb6! f5 5.Rc8! g3 6.a8Q Rxa8 7.Rxa8 f4 8.Rf8! Kg4 9.Kc5 f3 10.Kd4 g2 11.Rg8+ Kf4 12.Rf8+ Kg3 13.Rg8+ Kf2 14.Ke4=; Black wins in the main line because he does not waste time with 3... Kg5(?) but pushes the pawns forward.

4.Kb6 f5!

4... g2 5. Rc1 Kf5 6. Rg1=;

4... Kf5 5. Rc5+ Kf4 6. Ra5 Rxa5 7. Kxa5 =;

4... Ra1 5. Rc3 =;

4... Ra3 5. Rc3 g2 6. Rc1 =;

5.Rc3! ...

5. Rc8 Rxa7 6. Kxa7 f4 7. Rg8+ Kh5 8. Kb6 Kh4 9. Kc5 f3 10. Rh8+ Kg4 11. Rf8 g2 -+;

5... f4

5... Rxa7 6. Rxg3+!=; 6. Kxa7? f4 -+;

6.Rc6+ ...

White's plan is to interpose the Rook on the a-file but it is not quite good enough. Black obtains a winning QvR ending.

6... Kg5

7.Rc5+ Kg4!

8.Ra5 g2!

8...Rxa5 9.Kxa5=;

9.Rxa4 g1Q+

This ending is lost for White because Black will blockade the a-pawn with his Queen an then advance and promte his f-pawn.

10.Kb7 Qh1+

11.Kb8 Qh8+

12.Kb7 Qg7+

13.Kc6 Qf6+

14.Kd7 Qf7+

15.Kd6 Qf8+

16.Kd5 Qa8+

17.Kc5 Kg3

Black wins. The f-pawn is free to advance.

Another difficult ending but it gives us an idea of the technical skill required at the very highest level. In this Euwe Centennial Year we will be looking at other endings from the career of this much admired World Champion.
