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, Jim Monaghan, Gerard O'Reilly , Alfred Balaian and Henryk Kalafut.
THIS WEEK

POSITION 229

White to play and WIN 

 

  FORSYTH NOTATION:8/8/1b3p1p/1P3P2/1K3kPP/8/8/3B4: 


LAST WEEK, POSITION 228

Nikolai Kopayev, (1914-78).

Soviet Master and Endgame Analyst. One of the worlds great experts on Rook endings. He was responsible for the section on these endings in Averbakh's original Comprehensive Chess Endings series but nowadays he has been largely forgotten.

 

  Kopayev, 1949

  FORSYTH NOTATION:4K3/4P3/6R1/2k5/8/r5p1/8/8:

This study is similar to one composed by Emanuel Lasker way back in 1890, with the same material, but Kopayev gives it a different finale. The idea that Lasker discovered became known as the Lasker manoeuvre and is worth remembering because it occurs in practical play. White's advantage lies in his superior King position but he has to find a way to deal with the checks from the Rook so that he has time to queen the e-pawn.

1.Kd7! ...

1.Kf7 Rf3+ 2.Rf6? (in order to win the King has to go back and come out at d7 as shown in the main line)... Rxf6+ 3.Kxf6 g2 4.e8Q g1Q l=;

1... Rd3+

1... Ra7+? 2. Ke6 Ra6+ 3. Kf7 Rxg6 4. e8Q! (not 4. Kxg6?? because of 4... g2 ) 4... g2 5. Qe5+ Kb6 6. Qd4+ Kb5 7. Kxg6;

2.Kc7! ...

Here we see the beginning of the Lasker type manoeuvre. The White King will from alternately guarding its pawn, oppose the enemy King and drive it eventually to the edge of the board where the coup de grace will occur.

3... Re3

3.Rg5+ Kb4

3... Kc4 4.Kd7 Rd3+ 5.Kc6 Re3 6.Rg4+ Kd3 7.Rxg3 wins;

4.Kd7 Rd3+

5.Kc6 Re3

5... Rc3+ 6.Kb6 Re3 7.Rg4+ Kc3 8.Rxg3 Rxg3 9.e8Q wins;

6.Rg4+ Ka5

As shown in the above variations; if the Black King retreats to the third rank, then Rxg3! wins;

7.Kd6! Rd3+

With 7... Kb6 not 8. Rxg3?? Rxg3 9. e8Q Rd3+ 10. Ke7 Re3+ with a draw but 8. Rg8! ( 8.Rg6! Kb7 9.Rxg3 Re1 10.Rg5! wins) 8 ...Rd3+ 9. Ke6 Re3+ 10.Kd7 Rd3+ 11. Kc8 Rc3+ 12. Kb8 Re3 13. e8Q;

8.Kc5! Re3

8...Rc3+ 9.Kd4! Rc8 10.Rxg3 Re8 11.Kc5 Rc8+ 12.Kd6 wins.

9.Rxg3! ...

A fitting climax to White's careful manoeuvring. The Rook cannot be taken.

9... Rxe7

10.Ra3 mate

Gens Una Sumas.
