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, Olivier Scalbert, Gerald O'Reilly and Jim Monaghan .

LAST WEEK, POSITION 272

Vasily (1881-1952) &Mikhail Platov, (1883-1938).

Latvian/Soviet Endgame Composers. The Platov brothers started composing independently of each other but by 1905 they were working as a team. Vasily was the most creative in the composing duo but they both needed each other for their talent to flourish. They were pioneers along with Troitsky, Kubbel and Rinck of a new emerging art form in chess, that of composing endgame studies with its own rules and competitions. Their compositions were of a high order. They built on earlier work but also made new discoveries in the field of endgame theory. They wrote together: 'Selection of Chess Studies' (Sbornik shakhmatnykh etyudov, 1928).

V. & M. Platov

White to Play and WIN 

FORSYTH NOTATION

:6B1/8/1P6/2p1r1p1/K5k1/3P4/8/8 w - - 0 1:

White's winning chances in this ending rely on him retaining his b-pawn. White is threatening to queen the b-pawn and somehow the Black Rook has to prevent this from happening. The endgame study leads to an interesting ladder movement between the White King and Black Rook which culminates in a theoretical ending of QvRP which in this situation is won for White.

1.b7! Re8

The Rook guards the queening square.

2.Be6+ Kf3

3.Bc8 ...

The Bishop blocks off the Rook from the queening square.

3... Re1

Black now threatens a skewer with Ra1+ followed by Rb1+ , drawing the ending by giving up the Rook for the b-pawn;

4.Be6! ...

4.Bd7? Ra1+ 5.Kb5 Rb1+ 6.Ka6 Rxb7 7.Kxb7 Ke3 8.Bf5 g4=;

4... Ra1+

He goes ahead with his plan but White has an ingenius reply.

5.Ba2! Rxa2+

The Rook is deflected and now has difficulty carrying out the skewer idea. The interesting duel between the White King and Black Rook proceeds.

6.Kb3 Ra1

6...Rd2 7.Kc3! (7.b8Q? Rxd3+ 8.Kc4 Rd2 9.Kxc5 Rf2! and a theoretical draw according to endgame tablebases) ...Ke3 8.b8Q Rxd3+ 9.Kc4 Rd4+ 10.Kxc5 Rg4 11.Qf8 Ke4 12.Kd6 Ke3 13.Qf5 Rg3 14.Ke5 White wins;

7.Kc2! ...

7.Kb2? is a mistake because of ...Ra4! when Black has the defence ...Rb4+;

7... Ra2+

The Rook cannot directly stop the b-pawn from queening so it has to go for the long checking sequence of moves.

8.Kc3 ...

The b-file is mined:. 8.Kb3? Ra1=; 8.Kb1? Ra4 wins for Black;

8... Ra3+

9.Kc4 Ra4+

10.Kxc5 Ra5+

11.Kc4 ...

The King has to go down the board because 11.Kc6 Ra6+ 12.Kc7? Ra7 wins for Black;

11... Ra4+

12.Kc3 Ra3+

13.Kc2 Ra2+

14.Kb3 Rd2

Finally the Rook checks come to an end and the b-pawn will be able to queen.

15.Kc3 Ke3

16.b8Q WINS

A possible continuation is 16...Rxd3+ 17.Kc4 Rd4+ 18.Kc5 Rg4 19.Qe5+ with a win according to the endgame tablebases.

A wonderful work of chess art composed nearly a hundred years ago. It needs a powerful chess program with endgame tablebases to appreciate all its intricacies. The Platov brothers at their best !!
