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.

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.
