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.

LAST WEEK, POSITION 355
Jean Taubenhaus,
(1850-1919).
Professional Player and Teacher. Born in
Poland but moved to Paris in 1883 and became a French citizen. Never
a brilliant tournament competitor but sometimes he could cause a
major upset.
Burn vs Taubenhaus
American Congress, 1889
Black to play and WIN (?)
FORSYTH
NOTATION:8/8/8/3N4/2p2Kp1/3b2P1/8/4k3 b - - 0 1:
This game took place in the 6th American Congress, New York in
1889. This was one of the greatest and wearisome chess events of all
time. It consisted of twenty players who had to play each other
twice. In the second round, draws did not count so some players found
themselves playing in total nearly fifty games !! The tournament
included all the strongest players of the day except Steinitz, the
World Champion, who had the task of editing the tournament book. He had high praise for Taubenhaus's conduct of this
ending but as we shall see later there were omissions in Steinitz's
analysis for White's moves. Amos Burn was worn out trying to defend
this long difficult ending but it does seem that with optimal play he
could have drawn it.
1... Kd2
Black decides on the plan of giving up the g-pawn,
advancing the c-pawn and corralling the Knight. We have to give
credit to Taubenhaus for finding this beautiful idea after many
hours of play. In practical play Black's plan works and only fails
against optimal defence. It seems that Black has no winning
chances if he holds on to the g-pawn: 1... Be2 2. Ke3 Bf1
3.Kf4 Bh3 4.Ke3 Bg2 5.Nf6 Bf1 6.Ne4 Kd1 7.Nf2+ Kc2 8.Nxg4 c3 9.Kd4
Kb3 10.Ne3+ and White will draw comfortably with the advance of the
g-pawn.
2.Kxg4 Be4!
3.Nb6? ...
3.Nc7! prevents the advance of the c-pawn(3... c3?
4.Nb5 c2 5.Nd4 =) 3... Bc6 seems best 4.Na6
Bb7 5.Nc7 Kd3 6.Nb5 Bc6 7.Na3 c3 8.Kf4... Black cannot make
progress. The White drawing plan for this position is as follows:
The King advances with the g-pawn. The Knight from a3 guards the
important "c2" square. If Black tries to make the manoeuvre Kd4-c5-b4
then White will control the important "d4" square. Fortunately for
White the Knight's hold on"c2"cannot be broken to Black's advantage.
The Knight at "a3" defends brilliantly because
it cannot be removed as the Bishop is of the wrong colour. The Black
King cannot attack the Knight without losing the pawn to a deadly
fork. The secret of understanding this remarkable position is in the
knowledge of the basic ending: KNvKBP. This kind of knowledge has
become much easier to acquire with the introduction of endgame
tablebases with chess computer programs.
3... c3
4.Nc4+ Kd3
5.Na3! ...
The only move to draw and extremely important, as
indicated in the above note.
5... Ke3!
Steinitz, the reigning World
Champion gave high praise to Black's conduct of the
ending.
Black's only hope of winning is to wait for a
mistake in the positioning of the enemy King and then dislodge the
Knight at "a3" with his King. He has to be careful which way he
goes. 5... Kd4?? 6.Nb5+ =; or 5... Kd2?? 6. Nb5 c2 7.Nd4 =;
6.Kg5? ...
This move throws away the
draw. 6.Kh5! is the important move that Steinitz and Burn missed.
It is logical because the King makes way for the quick advance of the
g-pawn and Black no longer has the time to dislodge the Knight.
6...Bf3+ 7.Kh4! Be2 8.g4 Bd3 (8...Kf4 9.g5 Kf5 10.Kg3 Kxg5 11.Kf2
Bc4 12.Ke3 Ba6 13.Kd4 =)9.Kh5 Kf4 ( 9...Be2 10.Kh4 Kf4 11.g5 Bd3
12.g6! Bxg6 13.Nb5 c2 14.Nd4 c1Q 15.Ne2+ =) 10.g5 Kf5 11.Kh6 Ke6
12.g6! Kf6 13.g7 Kf7 14.Kg5 Kxg7 15.Kf4 Kf6 16.Ke3 Ba6
17.Kd4=;
6... Bd3!
The Bishop corrals the Knight and stays on the
important b1-h7 diagonal. Taubenhaus grabs his chance to win against
a player who was amongst the top players in the world.
7.Kf6 Kd4!
Black plays for the winning manoeuvre to dislodge
the Knight from "a3" so that the passed pawn can advance. The advance
of the g-pawn is too slow but White has no reasonable moves.
8.g4 Kc5!
9.Ke5 ...
9.g5 Kb4 10.g6 is again
too slow.
9... Bh7!
9... Kb4? 10. Kd4 Bg6
11. Nb5 c2 12. Nc3 =;
10.g5 Bg6
11.Kf6 Kb4
12.Kxg6 Kxa3
13.Kf7 c2
14.g6 c1Q
15.g7 Qf4+ 16.Kg6 Qg4+ 17.Kf7 Qf5+
18.Kg8 Kb4;
Black has an elementary win and White soon resigned. With the help of a tool of the new age, computer
analysis, we see that Taubenhaus played this ending accurately but
Burn was lack lustre. Steinitz with the publication of the 1889 New
York Tournament book gave us an important historical record of this
event. At that time he was the best player and analyst around and his
theories about the game pushed forward its development. But we have discovered omissions in Steinitz's
commentary and analysis of the final phase of this game. I suppose we
have to ask the awkward question: How much of 19th century
tournament analysis and game commentary can we really trust as being
accurate ?
