Welcome to this active site. Each week I am going to present to you an 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, Gerard O' Reilly, Henryk Kalafut, Federico Giallombardo, Jim Monaghan, Jon Palmer and Alexander Voyna.

 LAST WEEK, POSITION 291

Emanuel Lasker, (1868-1941).

German Grandmaster. World Champion from 1894-1921. The Moscow 1925 International tournament had an immense impact on the growth of chess in the Soviet Union. The chief stars were Capablanca and Lasker, and the Moscovites turned out in their thousands to see their chess idols in action. The whole nation was gripped by "chess fever" and it was to last a long time.

The tournament was won by Bogolyubov (15.5), ahead of Lasker (14), Capablanca (13.5), Frank Marshall (12.5), and Savielly Tartakower and Carlos Torre (12). Considering his age and the glare of publicity, the Moscow result with Lasker coming second must be looked upon as a great success for him.

Black to Play and WIN

 

FORSYTH NOTATION

:6k1/4bpp1/1nq1p2p/pp1b4/3P4/PPQ2BPP/1B1N1PK1/8 b - - 0 1:

Black simplies the position by swapping the light squared Bishops and then exchanging the Queens. He achieves an ending in which he has a big positional advantage on the queenside.

1... Bxf3+!

2.Nxf3 ...

2.Qxf3? Nd5! 3.Ne4 Qc2 and Black will pick up material.

2... Qxc3

3.Bxc3 a4!

If now 4.b4 Black will win easily with 4...Nc4.

4.bxa4 bxa4

5.Kf1 ...

White was faced with a difficult choice. Defending the pawn with 5.Bb4 Bxb4 6.axb4 leads to a lost ending. The outside passed a-pawn will tie down the White Knight, i.e. 6... a3 7.Nd2 a2 8.Nb3 Kf8 9.Kf1 Ke7 10.Ke1 Nd5 11.b5 Nc3 12.b6 Kd6 13.Kd2 Na4 14.b7 Kc7 15.Kc2 Kxb7 16.Na1 Kc6 17.Kb3 Nb6 18.Kxa2 Kd5 19.Nc2 Kc4 20.Kb2 Kd3 and Black wins. Rubinstein decides to give up the a-pawn and hope for counter chances with an active King and his remaining pieces.

5... Bxa3

6.Ke2 Kf8

7.Kd3 Nd5

8.Be1 Bd6

9.Kc4 Ke7

10.Ne5 Bxe5

White's best-placed piece is removed and the outside passed a-pawn will win for Black.

11.dxe5 Kd7

12.Bd2 ...

12.Kb5?? a3 wins.

12... h5

13.Bc1 Kc6

14.Ba3 Nb6+

15.Kd4 ...

If 15.Kb4 the Black King penetrates the kingside, eg 15...Kd5 16.Bb2 16...Ke4 17.Kb5 Nd7 18.Kxa4 Nxe5 19.f4 Nd3 20.Bxg7 Kf3 -+;

15...Kb5

16.Bf8 Nc4

17.Kc3 g6

18.f4 Ne3

19.Kd3 Nd5

Threatening ...h4 to break up the pawn chain.

20.Ba3 ...

20.h4? Nb6 21.Kd4 Nc4 22.Kc3 (if 22.Kd3 a3 23.Bxa3 Nxa3-+) 22...Ne3 23.Kb2 Nf5 -+;

20... h4!

21.gxh4 Nxf4+

22.Ke4 Nh5!

22...Nxh3?? is a blunder because of 23.Kf3 Ng1+ Kf2 with continue harassment of the Knight.

23.Kf3 Kc4

Black invades.

24.Bb2 Kb3

25.Ba1 a3

26.Kg4 Kc2

27.Kg5 Kd3

White resigns.

Gens Una Sumas. 
Gerard O' Reilly wins in May.
