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,

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

BLACK to play and WIN

FORSYTH NOTATION:3n4/5k2/8/2p1B1pp/1pP1Pp2/1P1K1P1P/8/8 b - - 0 1:

It is good training to try initially to solve the endings without the assistance of a chess playing programme.

LAST WEEK, POSITION 348

Hermann Mattison, (1894-1932). 

Latvian chessplayer and study composer. He won the first Latvian championship in 1924 and the first FIDE World Amateur Championship in Paris in the same year. He played first board for the Latvian team at the Prague Olympiad in 1931 and he scored wins against Alekhine, Rubinstein and Vidmar. He composed over 60 studies, many of which are of great artistic value.

 Mattison, 1927

WHITE to play and WIN

FORSYTH NOTATION :8/8/p2P2k1/N1P4p/5K2/8/8/3r4 w - - 0 1:

Usually in these type of endings the Knight is no match for the Rook because of it's lack of mobility. The Rook always seems to have great capacity to eat up pawns while the slow plodding Knight is left struggling to cope.

White in this ending has a number of positional factors in his favour. The passed pawns are well advanced and Black has not been able to get his King in front of the pawns to blockade their advance. White pushes the c-pawn which is the candidate for promotion, allowing the d-pawn to be taken. It then requires careful manoeuvring by the White King to escape the attention of the Rook. White needs respite from the checks to have time to play the Knight to "c6"(d8) so that it can act as a shield for the new Queen. Notice how the White King travels down and up the board along the same dark squares. It is one of Mattison's finest compositions. The ending is very instructive.

White has to act quickly otherwise the h-pawn will be advanced or the Black King will blockade the pawns.

1.c6! ...

1.Ke5? h4! 2.c6 h3 3.c7 h2 4.c8Q h1Q =;

1.Nb7? Kf6! 2.c6 Ke6 3.c7 Rc1 4.Kg5 Kd7 wins;

1... Rxd6

2.c7! ...

Black can now harass the enemy with Rook checks. White in order to make progress has to seek shelter at "g1".

2... Rf6+

3.Ke3! ...

3.Ke5? Rf5+ 4.Kd6 Rf6+ 5.Kc5 Rf8 6.Nc6 h4 7.Nd8 Rf1 8.Nc6 Rf8=;

3.Kg3? Rf8 4.Nc6 h4+! 5.Kg4 h3 6.Nd8 h2=; 3.Ke4!? +- takes longer to win;

3... Re6+!

3...Rf8 4.Nc6 Re8+ 5.Kf4 Rf8+ and follows as in main line;

4.Kf2! ...

4.Kd4?? Re8 5.Nc6 Kf6! 6.Nd8 Ke7! 7.c8Q Rxd8+ 8.Qxd8+ Kxd8 and Black wins.

4.Kd3?? Re8 5. Nc6 Kf7 6.Ne5 Ke6 7.Nf3 h4 8.Ke3 Kd7+ wins;

4... Rf6+

5.Kg1! ...

This is the best square because the king has to be away from the advancing h-pawn.

5.Kg2? Rf8 6.Nc6 h4! 7.Nd8 h3+! 8.Kg3 h2 =;

5... Rf8

The respite from the checks gives White the chance to play the Knight to "c6" from where it will be able to shield the new Queen.

6.Nc6! ...

The Knight threatens 7.Nd8 shutting out the Rook from the queening square.

6... Re8!

This stops the threat of 7.Nd8 because of ...Re1+ and then ...Rc1 winning for Black.

7.Kf2 Rf8+

White has the winning plan of marching the King up the board to "d6" where Black will have no meaningful checks .

8.Ke3 Re8+

9.Kf4! ...

9.Kd4? Kf6 10.Na7 h4 and Black wins.

9... Rf8+

10.Ke5! Re8+

11.Kd6 Kf6

12.Nd8! Re1

This fails because the Knight will be able to shield the new queen from "c6".

13.c8Q Rd1+

14.Kc7 Rc1+

15.Nc6! WINS.

A beautiful ending which is worthy of a great composer.
