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, Federico Giallombardo, Jon Palmer, Henryk Kalafut, Gerard O' Reilly, Alexander Voyna and Jim Monaghan .

LAST WEEK, POSITION 283

Alexander Alekhine, ( 1892-1946 ).

World Champion from 1927-35, 37-46. He was a genius at chess and many rate him as one of the greatest players of all time. In his best years he stood head and shoulders above his rivals. In the great international tournament at Bled in 1931 Alekhine showed his class by outdistancing the second prize winner by five and a half points !! For all his faults he made a lasting contribution to the World of Chess. He was a brilliant annotator and has left a collection of beautiful games.

Alekhine vs Kostich

Bled, 1931

White to Play and WIN

FORSYTH NOTATION

:6k1/3r1p1p/q1Nb1np1/3p1p2/1B1P4/4P3/P1Q2PPP/2R3K1 w - - 0 1:

Kostich has played the middlegame badly and now finds himself a pawn down. Alekhine simplifies the position by exchanging some pieces to reach a won RBP vs RNP ending in which his extra outside passed pawn will decide the game. The following are the actual moves played in the game:

1.Nb8 Bxb8

2.Qc8+ Qxc8

3.Rxc8+ Kg7

4.Bf8+ Kh8

Playing 4...Kg8 allows mate in three starting with 5.Bh6+;

5.Rxb8 h5

Making room for the king to move.

6.Bd6+ ...

Another way to win is to play: 6.f3! Kh7 7.Bc5 Rc7 8.a4 Nd7 9.Rb5 Rc8 10.a5+-;

6... Kh7

7.Be5 Ng8

This move is forced. If 7...Kg7 8.Rb6 wins;

8.h4 f6

9.Bf4 Ra7

10.Rb5 ...

Probably better here is 10.Bd3! and if Black plays 10...Rxa2? 11.Rb7+ Kh8 12.Bf8 +-;

10... Nh6?!

Black could have held out longer with: 10...Rxa2 11.Rxd5 Ra7 But with the eventual advance of the White d-pawn the win is not in doubt.

11.a4! ...

The powerful outside passed pawn advances. Capturing on a4 is impossible due to the loss of the Knight on h6 after Rb7+;

11... Nf7

Black doesn't have time to set up an effective blockade.

12.a5 Nd8

13.Bb8! ...

White secures the a-pawn which would be lost after 13.Rxd5 Nc6!;

13... Rd7

14.a6 Nc6

15.Rb6 Nxb8

16.Rxb8 ...

The threat is 17.Rb7 winning immediately.

16... Kh6

17.Rb7 Rd6

18.a7 Ra6

An instructive position. The Black King is cut off from play and the Rook alone cannot stop White's winning plan of marching his King to the queenside and up the board to b8 to aid the promotion of the a-pawn.

19.f4 Ra2

20.Kf1 g5

21.g3 ...

Here Black resigned. A wonderful ending by Alekhine.

Gens Una Sumas. 
Jon Palmer wins in March.
