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, Steven B. Dowd, Henryk Kalafut, Alexander Voyna, Jon Palmer and Gerard O'Reilly.

  LAST WEEK, POSITION 301

Mark Liburkin,(1910-53).

Soviet study composer. Followed in the footsteps of Troitsky, Kubbel and the Platov brothers. His early death robbed the world of a truly great composer who showed purity, economy and originality in his endgame compositions.

M. Liburkin, 1939 

White to play and WIN 

 

FORSYTH NOTATION :8/2N5/7N/p7/8/1K4p1/2P5/4k3 w - - 0 1: 

Black's best defence is to try and reach a theoretical draw with lone King against two Knights. The g-pawn will soon be lost and Black will use his advancing a-pawn to deflect the White King from the defence of the c-pawn. Black desires a swap of the pawns in order to draw. But White has a surprise in store for his opponent as he keeps hold of the c-pawn and allows the a-pawn to queen. A delightful endgame study.

1.Nf5 g2

1...Kd2 2.Nb5 g2 3.Nh4 a4+ 4.Kb2g1N 5.c4 Ne2 6.c5 Nf4 7.c6 Nd5 8.Ng6 Ke3 9.Ka3 Nb6 10.Ne7 Ke4 11.c7 +-;

1...a4+ 2.Kc3! g2 3.Nh4 g1Q 4.Nf3+ Kd1 5.Nxg1 a3 6.Nd5 as in main line;

2.Nh4 g1Q

Black goes for this promotion because it gives him time to push the a-pawn while at the same time attacking the c-pawn. He is seeking exchange of the pawns leading to a theoretical draw. Arguably this is the best shot at a draw. Other variations in which Black promotes the g-pawn to a Knight lead to a clearly lost ending in which the c-pawn becomes too powerful. White in order to win only has to avoid any Black sacrifice of the Knight for the advancing pawn.

2...g1N 3.c4 Ne2 4.Ne6 Ng3 5.c5 Ne4 6.c6 Nd6 7.c7 Kd2 8.Ka4 Kd3 9.Nf5 Nc8 10.Kxa5 Ke4 11.Ned4 Kd5 12.Ka6 +-;

2...a4+ 3.Kc3 g1N 4.Nb5 Ne2+ 5.Kb4 Kd2 6.c4 Nc1 7.Kxa4 Nd3 8.Ka5 Ke3 9.Ng6 Nc5 10.Nc3 Nd3 11.Kb5 Kf3 12.Nd5 Ke4 13.Ngf4 Ne5 14.c5 Kf5 15.Nh5 Ke6 16.Nb6 Ke7 17.Nf4 Kd8 18.Nc4 Nf7 19.c6 Ng5 20.Kb6 Ne4 21.c7+ +-;

3.Nf3+ Kd1

4.Nxg1 a4+

5.Kc3 a3

It looks as if White cannot stop the a-pawn without losing his c-pawn, thus leading to a draw. But White has a surprise.

6.Nd5! a2

7.Ne3+! ...

7.Kb2? a1Q+ 8.Kxa1 Kxc2=;

7... Kc1

7...Ke1? 8.Kb2 +-;

8.Ne2+ Kb1

9.Kd2! ...

So in order to win White doesn't need to stop the a-pawn. He has a direct mating attack instead.

9... a1Q

9...Kb2 10.Nc4+ Kb1 11.Nc3+ Ka1 12.Nxa2 with a win.

10.Nc3+ Kb2

11.Nc4 MATE.

A delightful study showing Mark Liburkin at his best.

Gens Una Sumas.


Antonio Senatore,
Henryk Kalafut and Alexander Voyna win in August.
