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, Jon Palmer, Henryk Kalafut, Alexander Voyna, Gerald O'Reilly and Jim Monaghan .

FORSYTH NOTATION :k1r5/B7/5p2/2p5/2p5/2K5/4B3/5N2:

The Bishops+Knight vs Rook ending is usually a theoretical win for the minor pieces. But in the above study it is complicated by the presence of the pawns and the fact that White's black-squared Bishop is short of retreat squares. White's immediate problem is how to extricate his Bishop. The Black King will chase it and win it but he finds himself caught in a horrible trap. If the pawns had been better situated then Black may have had real chances of drawing the final phase of the ending. It is a remarkable study.

1.Bb6 Kb7

2.Ba5 Ka6

2... Kc6? 3.Kxc4 Rh8 4.Bf3+ Kd6 5.Be1 f5 6.Bg3+ Ke6 7.Kxc5 White makes progress.

3.Nd2! Re8

Black removes his Rook from danger, so that now both Bishops are threatened with capture. 3...Kxa5? 4.Nxc4+ Ka4 (4...Ka6 5.Nd6+) 5.Nb6+ White wins;

4.Bf1! Kxa5

At first it seems that Black has equalised but the King is very vunerable in this position. The alternative 4...Kb5 5.Nxc5 Rh8 6.Bb6 etc. will eventually lead to the theoretical 2B+N v R ending which is won for White.

5.Nxc4+ Ka4

6.Bg2! ...

The Bishop now heads for the a4-e8 diagonal where Black will be forced to give up his Rook.

6... Re6

6...Rb8 7.Bc6+! Rb5 8.Nd6 with a win.

7.Bd5! Ra6

The Bishop now gets to the important diagonal via another route.

8.Bf7! ...

Threatening 9.Be8+ Rc6 10.Bxc6 mate;

8... Kb5

8... Ra5 9.Be8+ Rb5 10.Nd6 or 8...Ra8 9.Nb6+ Kb5 10.Nxa8 White wins.

9.Be8+ ...

A devastating check.

9... Rc6

10.Kd3! ...

The pinned Rook is lost with no compensation.

10... f5

A move that Black would rather not make.

11.Ne5 c4+

12.Kd4 c3

13.Bxc6+Wins

The pawns will soon be captured and White can then mate with the Knight and Bishop.

Gens Una Sumas.
