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, Steven B. Dowd, Andrew Watt, Henryk Kalafut, Alexander Voyna and Gerard O'Reilly.

LAST WEEK, POSITION 299

Claude Sansom, (1914- ).

British Composer of Endgame Studies. Sometime ago while on holiday in Wales I came upon Claude's book: End-game studies which was produced by the composer himself in the nineties. Perhaps not many original works of art among the 156 compositions but a labour of love and a tremendous achievement by the composer.

White to play and WIN

FORSYTH NOTATION

:1n5k/4q3/6K1/3p2p1/8/6p1/1p1Q4/5n1r w - - 0 1: 

White is serious material down but due to the unfortunate position of the enemy monarch in the corner has a way to victory. The main charateristic of this study is the long series of checks given by the Queen as she ascends and descends an imaginery ladder which lead to a forced win. Another name for this strategem is the "stepping-stone" manoeuvre as the Queen marks out imaginary steps on the board. These ascending and descending movements have also been described as "staircases" or "escalators".

1.Qc3+ Kg8

1... d4? 2.Qc8+ wins;

2.Qc8+ Qf8

3.Qe6+ Kh8

4.Qe5+ ...

The Queen now descends the "staircase" or "ladder" in the first of three such movements.

4... Kg8

5.Qxd5+ Kh8

6.Qd4+ ...

To capture the Black Rook with the diagonal a1-h8 closed is a mistake: 6.Qxh1+?? Nh2 7.Qd1 Qg7+ 8.Kf5 Qd7+ 9.Qxd7 b1Q+ 10.Ke6 Qe4+ 11.Kd6 Qd4+ 12.Kc7 Qxd7+ -+;

6... Kg8

7.Qc4+ Kh8

8.Qc3+ Kg8

9.Qb3+ Kh8

10.Qxb2+ ...

The Queen opens up this important diagonal for the later Qa1+ and now ascends the "ladder".

10... Kg8

11.Qb3+ Kh8

12.Qc3+ Kg8

13.Qc4+ Kh8

14.Qd4+ Kg8

15.Qd5+ Kh8

16.Qxh1+ ...

These long manoeuvres are beginning to pay off as the Queen wins the Rook with check. This opens up the h-file for the finale but first White has to work round the blockading Knight.

16... Nh2

17.Qa1+ ...

The Queen carries out the "stepping-stone" manoeuvre for the last time.

17... Kg8

18.Qa2+ Kh8

19.Qb2+ Kg8

20.Qb3+ Kh8

21.Qc3+ Kg8

22.Qc4+ Kh8

23.Qd4+ Kg8

24.Qd5+ Kh8

25.Qe5+ Kg8

26.Qe6+ Kh8

27.Qh3+ Qh6+

27...Kg8 28.Qh7 mate,

28.Qxh6+ Kg8

29.Qg7 Mate.

Not too difficult to solve but a memorable example of chess art. 

Gens Una Sumas.


Antonio Senatore,
Henryk Kalafut and Alexander Voyna win in August.
