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, Pablo Pena, Henryk Kalafut, Gerard O' Reilly and Alexander Voyna.

 LAST WEEK, POSITION 286

Markovich Simkhovich, (1896-1945).

Soviet composer of chess problems and endgame studies. Simkhovich made an original contribution to the endgame study by bringing a number of ideas from the problem world and reworking them in an endgame setting. One of his outstanding achievements was formulating and categorising the theme of the "positional draw".

 

Simkhovich, 1926

White to Play and DRAW 

FORSYTH NOTATION

:N3kb2/pq4p1/4B1P1/1p1P2B1/p7/3P4/2P5/2K5 w - - 0 1:

In 1928` Simkhovitch wrote his ground breaking paper on the "positional draw". He mentioned about studies where a draw is obtained by the creation of an impenetrable position, a fortress. Another type is where the enemy forces find they are "bound up", i.e. they are committed to defend certain points and so are distracted away from winning. He used the above study to illustrate some of his ideas.

1.Bf7+ ...

1.Nc7+? Qxc7 2.Bf7+ Qxf7! 3.gxf7+ Kxf7 Black is winning because of the extra pawn and widely separated passed pawns.

1... Kd7

2.Be6+ Kd6

Now the other Bishop chases the King.

3.Bf4+ Kc5

4.Be3+ Kb4

5.Bd2+Ka3

Has the King escaped the checks ?

6.Kb1! ...

No, White is threatening perpetual check beginning with Bc1+.

6...Qxa8

Black plays the only move to evade the perpetual.

7.Bc1+? would now be a mistake 7...Kb4 8.Bd2+ Kc5 9.Be3+ Kd6 10.Bf4+ Ke7 11.Bg5+ Ke8 12.Bf7+ Kd7 13.Be6+ Kc7 and the King escapes.

7.Ka1! ...

A wonderful fortress position. Simko's key theme shines through: the powerless Queen and the superior Bishop. White is a Queen for a Bishop down but his opponent has no winning moves ! 7...b4 and 7...Bb4 both allow 8.Bc1#; Any other bishop move allows a perpetual; 7...Qe8 prevents the king from escaping the checks. There are no reasonable moves to escape the draw.

7... Qb7

Black can also play 7....a5 or 7...a6 but they do not alter the situation.

8.Kb1! ...

There is nothing positive Black can undertake.

8... Qa6

8...Qc7 9.Bc1+ kb4 10.Bd2+ Qc3 11.Bxc3 Kxc3 12.Bd7=

9.Ka1! Qb7

10.Kb1! Qa8

11.Ka1! DRAW

It is a positional draw. Black can make no progress. Harrie Grondijs has written an enjoyable book on this brilliant composer: "Works of Simkhovich" (1996?) 

 

Gens Una Sumas. 
Alexander Voyna, Antonio Senatore and Henryk Kalafut win in April.
