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, Steven B. Dowd, Christos
Gitsis and Valdir Uchoa Jr.

solve the endings without the assistance of a chess playing
programme.

LAST WEEK, POSITION 349
Mikhail Botvinnik,
(1911-1995).
World Champion (1948-57, 1958-1960,
1961-63). Three years after first winning the World
Championship Botvinnik had to defend his title against David
Bronstein. It was a hard fought clash which produced many exciting
games and only one draw < 25 moves. (In marked contrast to a
recent WC match). Botvinnik had not taken part in chess
competitions since winning the World Championship in 1948. Because of
this he was out of form and found it difficult to cope with his
brilliant young opponent. But Botvinnik demonstrated his great
fighting abilities as he overcame a one point deficit, winning the
penultimate game and drawing the final game to thus keep the
title.
Bronstein vs Botvinnik,
WC 1951, Game 10
BLACK to play and WIN
FORSYTH
NOTATION:3n4/5k2/8/2p1B1pp/1pP1Pp2/1P1K1P1P/8/8 b - - 0 1:
Botvinnik was very critical about his lack of form in this
match. Even his home analysis which was one of his strong points in
his long career was letting him down. This position arose shortly
after the adjournament so it must have been covered in his home
analysis. Botvinnik played 1...Ke7? 2.Bg7! Nb7?
and could only draw the ending. It was
Stahlberg, a former World Championship
candidate contender himself, who pointed out the winning move 1... Kg6!! Black has a
positional plus here because he has the possibility of creating a
passer with a g-pawn breakthrough. If Black can play his
Knight safely to d4 then the weak pawns at b3 and f3 look vulnerable.
But first Black needs to advance his King and reposition the Knight
to prepare the g4 push.
1... Kg6!!
1...Ke7? The move Botvinnik played. Now White plays the Bishop to the short f8-h6
diagonal from where it can harass pawns on both sides of the board
tying down the enemy Knight and King. 2.Bg7! Nb7? (With 2...
Kf7! and then 3...Kg3! Black would be back to the main line) 3.Bh6 Kf6 4.Bf8 Kf7 5.Bh6! Kg6 6.Bf8 Kf6 7.Ke2 Kf7
8.Bh6 Kg6 9.Bf8 Kf6 10.Kd3 Agreed draw;
2.Bd6 ...
2.Ke2 Nc6! 3.Bd6 Nd4+
4.Kd3 Nxb3 5.Be7 g4 or 5 ...h4 -+;
2.Bc7 Ne6 3.Be5
transposes to the main line;
2... Ne6!
The knight defends the pawns
and threatens to invade via d4. Black is ready to make the important
pawn breakthrough.
3.Be5 g4!
4.hxg4 hxg4
5.Ke2 ...
5.fxg4 Kg5 6.Ke2 Kxg4
7.Bf6 Kg3 8.Kf1 Nd4! -+;
5... g3!
Black is threatening to bring the King to
h3.
6.Kf1 Kg5
7.Bd6 ...
Now the Knight can get to d4 and either the b or
f-pawn will fall.
7... Nd4! 8.Be7+ Kh5 9.Bxc5 Nxf3 10.e5
Nd2+ 11.Ke2 Ne4
12.e6 Kg6 13.Bb6 Ng5 14.c5 f3+ 15.Ke1
f2+ 16.Ke2 Nxe6
17.Kf1 Kf5 18.c6 Ke4 19.Ba7 Nc7! 20.Kg2
Kd3 WINS.
