PRACTICAL CHESS ENDGAME 24/06/2001

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, Henryk Kalafut, Paul Cheng and Graham White.

L. Mitrofanov,

Leningrad 1967,

White to play & WIN

FORSYTH NOTATION:8/k7/P2b2P1/KP1Pn2P/8/8/7p/4n3:

Black has a huge material advantage with his three extra pieces and the h2 pawn near to queening. White's only hope is to attack with his pawns:

1.b6+! ...

1.g7? Nc4+ 2.Ka4 Nb6+ 3.Kb3 ( 3.Ka5 Nc2 4.g8Q Bb4++) 3...h1Q 4.g8Q Qf3+ 5.Ka2 Qa3+ 6.Kb1 Qb3+ 7.Kc1 Qc2++;

1... Ka8!

1...Kb8? 2.g7 Nc4+ 3.Kb5 Nxb6 4.Kxb6 Bc7+ 5.Kc6 h1Q 6.g8Q+ Ka7 7.Qc8 wins;

2.g7 h1Q

Other moves lose much quickly:

2...Nc4+? 3.Kb5 h1Q 4.g8Q+ Bb8 5.a7 Qh2 6.axb8Q+ Qxb8 7.Qxb8+ Kxb8 8.Kxc4 wins;

2...Bb8? 3.a7 Nd7 4.g8Q h1Q 5.Qe6 Ne5 6.b7+ Kxb7 7.Qb6+ Kc8 8.axb8Q+ Kd7 9.Qd8++;

3.g8Q+ Bb8

4.a7 ...

The threat of mate now hangs over Black. Can he attack with his extra material?

4... Nc6+

Black gives up the Knight so that his queen can attack along the fifth rank.

5.dxc6 Qxh5+

6.Qg5!! ...

With this move Mitrofanov claims a place in the Hall of Chess Fame. The White Queen is given up to deflect Black's main attacking piece to an inconvenient dark coloured square. This move and the idea behind it has become known as MITROFANOV'S DEFLECTION. Computer analysis indicates the correctness of the idea. The alternative King moves do not lead to a clear win as the Monarch is exposed to checks:

6.Ka4? Qd1+ 7.Qb3 Qd4+ 8.Kb5 Qe5+ 9.Ka6 Qa1+ 10.Kb5 Qe5+=;

6.Kb4? Nc2+ 7.Kc3 Qc5+ 8.Kd2 Qe3+ 9.Kxc2 Qc5+=;

6.Ka6? Qe2+ 7.Ka5 Qe5+ 8.Ka6 Qa1+ 9.Kb5 Qe5+=;

6... Qxg5+

7.Ka6! ...

Black is lost. The passed pawns are stronger than the three pieces. He is forced to give up the Bishop and Queen, it doesn't matter in which order, to survive a few more moves.

7... Qa5+

7...Bxa7 8.c7! Qa5+ 9.Kxa5 Kb7 10.bxa7 wins;

8.Kxa5 Bxa7

8...Nd3 9.c7 Bxc7 10.bxc7 Kb7 11.a8Q+ wins;

9.c7 Kb7

10.bxa7 WINS.
