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, Rainer Staudte, Josep S.
Blanes and Valdir Uchoa Jr.

programme.

White to play and DRAW
FORSYTH
NOTATION:8/2n1pK2/4Pb1P/3P4/p2k4/8/8/8 w - - 0 1:
Black has a large material advantage and a dangerous passed
pawn. White's only hope of salvation is in the progress of his own
pawns. So his first move, the advance of the threatened d-pawn, is
not difficult to find. The interesting feature of this study is the
underpromotions: two White pawn underpromotions to a Knight and the
Black a-pawn underpromotion to a Rook.
1.d6! Nb5!
1... Nxe6? 2. Kxe6 a3
3. d7 a2 4. d8Q+ Kc3 and Black has little chance of winning.
2.dxe7 ...
2.d7? Nd6+ 3.Kg8 Nb7
-+;
2... Ke5
2...Be5? 3.e8Q Nd6+
4.Kf8 Nxe8 5.Kxe8 a3 6.Kf7 a2 7.e7 a1Q 8.e8Q =;
3.e8N! ...
This pawn underpromotion to a
Knight is the only way for White to survive. 3.e8Q?
Nd6+ 4.Kf8 Nxe8 and Black wins.
3... Bh8
3...a3 4.Nxf6 Nd6+
5.Kf8 Kxe6 6.h7 Nf7 7.Ne4 a2 8.Ng5+ Nxg5 9.h8Q Nh7+ =;
4.Kg8 ...
White has to counter the threat from the Black
a-pawn.
4.h7 is also possible,
4... a3 5.Kg8! Kxe6 6.Kxh8 Kf7 etc. as in main line.
4... Kxe6
5.Kxh8 Kf7!
Black plays to imprison the White monarch.
6.h7! a3
6...Nd4 7.Nf6 a3 8.Nd7
a2 9.Ne5+ Kf8 10.Ng6+! Kf7 11.Ne5+ =;
7.Nd6+ Kf8!
7...Nxd6 stalemate.
8.Nxb5 a2
9.Nd4! ...
9.Nc3? a1R! 10.Nb5 Kf7
11.Nc7 Ra7 12.Ne8 Rd7 13.Nd6+ Kg6 14.Nf7 Rxf7 15.Kg8 Rxh7 and Black
wins.
9... a1R!
This avoids the 9...a1Q
stalemate.
10.Ne6+ Kf7
11.Nd8+ Kg6
12.Kg8 Ra8
13.h8N+! ...
Again White is saved by the
underpromotion to a Knight.
13... Kf6
14.Nhf7 DRAW.
