ALL RIGHTS RESERVED

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, Henryk Kalafut, Gerard O'Reilly, Christos Gitis, Josep S. Blanes and Valdir Uchoa Jr.
THIS WEEK

POSITION 353

Black to play and WIN

FORSYTH NOTATION:8/8/3p1k2/3P4/2Pp4/6P1/P3R1K1/2r5 b - - 0 1:

It is good training to try initially to solve the endings without the assistance of a chess playing programme.

LAST WEEK, POSITION 352

Evgeny Somov-Nasimovich, (1910-1942).

Soviet Endgame Composer. Showed great promise at an early age but his career was brought to a sad premature end with his death during the Second World War.

Somov-Nasimovich, 1939

White to play and DRAW

 

  FORSYTH NOTATION:7b/2R2Pq1/4b1B1/4P3/8/8/1PP5/K4k2 w - - 0 1:

White faces a serious threat along the a1-h8 diagonal from the Queen-Bishop battery and also has to be aware of a back rank mating attack from the Queen. Fortunately with the help of his f-pawn promoted to a new Queen he finds a brilliant defence to bring about stalemate.

1.Re7! ...

The Rook attacks the Bishop and guards the f-pawn. White cannot allow the f-pawn to drop because its threatened promotion is the main defence.

1.Rc6? Bxf7 2.Rf6+ Ke2! (2...Qxf6? 3.Bd3+! Ke1 4.exf6 Bxf6 =) 3.Bxf7 Qg1+ 4.Ka2 Bxf6 5.Bc4+ Kd2 6.exf6 Kxc2 7.Bb3+ Kc1 8.Bc4 Qb6 9.Ka3 Qxf6 and Black wins

1... Qxe5!?

This is the composer's move and it leads to exciting play but 1...Bd5! 2.Rd7 (2...Bf3!) Be6 3.Re7 Bc4 4.Rc7 Bd5 5.Rd7 (5...Be6 6.Re7 positional draw) 5...Bf3! makes the draw problematic with a possible continuation: 6. Rd3 Kf2 7. Rd2+ Kg1 8. c3 Qh6 9.Rd3 Kf2 10. e6 Bf6 -+;

2.f8Q+ Kg1!

2...Bf6 3.Bd3+ Kg2 4.Rg7+ Bxg7 5.Qf1+ Kg3 6.Qg1+ Kh4 7.Qf2+ Kg5 8.Qd2+ Kf6 9.Qc3 Qxc3 10.bxc3 =;

3.c3 ...

White takes care of the initial threat but Black has a Queen sacrifice in mind.

3... Qe1+

4.Bb1 Qxc3!!

A beautiful conception but White has a wonderful "save".

5.Rg7+ ...

White's only saving move.

5... Bxg7

Black's threats are awesome but White finds a wonderfully illogical combination. He offers to give away his Queen and Bishop to bring about stalemate. If the stalemate is rejected then White can always seek refuge in the KB v KBB ending which is theoretically drawn.

6.Qf1+!! Kxf1

The first sacrifice has to be accepted: 6...Kh2? 7.Qf2+ Kh3 8.Bf5+ Bxf5 9.Qxf5+ Kh4 10.bxc3 +-; 

7.Bd3+! Ke1

7...Qxd3 stalemate. Black throws his King into the attack.

8.bxc3 Kd2!

9.Bc2! ...

9.Be4? Kc1! -+;

9... Kc1!

9...Kxc2 stalemate.

Black has one last go at winning but White's reply is easy to see.

10.Bb3! Bxb3

STALEMATE.
