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.

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

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.
