PRACTICAL CHESS ENDGAME or BRIAN'S CHESS FOLLY. 28/3/99

Welcome to this active site. Each week I am going to present to you a 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.

White to Play & WIN  

 

FORSYTH NOTATION:4rn1k/1p3bpp/p7/3p1PP1/3P1N2/3Bq3/PP3Q2/6RK:

Solution will be presented on 11th April. 


LAST WEEK, POSITION 82

Vsevolod Rauzer (1908-1941) was a Soviet master and a brilliant theoretician. He shared first place in the championship of the Ukraine in 1933 and came second in the Leningrad Championship of 1936. He played several times in the Soviet championship, his best result coming in 1933 when he came 6th. He is best remembered for his theoretical contributions to the Sicilian Defence where an important variation bears his name. He is less well known for a magnificent study of the ending BPvP (in the case of the Rooks pawns) where he was able to define the winning zone. In 1937 his career was tragically cut short by a serious illness. 

Rauzer, 1928

White to Play & WIN  

 

FORSYTH NOTATION:8/8/k1K5/8/pB6/P7/8/8: 

Kling and Horwitz first looked at this position in 1851 but it was Rauzer who worked out the theory of these type of endings in the late 1920's. White has to win the a-pawn and not allow the Black King to reach a8. If the King reaches this square the position is a theoretical draw because the Bishop being of the "wrong colour" cannot drive out the monarch. The White a-pawn will never be able to queen.

1.Bc5! ...

The King is barred from reaching a8.

1... Ka5

2.Kb7 Kb5

3.Bb6! ...

The Black King is forced to move down the board. 3.Bb4 is also good; 3...Kc4 4.Kc6 Kd4 5.Bd6! Ke4 (if Kc4 6.Bc5 will force the King further away from the pawn, which makes it easy for white) 6.Kb5 Kd5 7.Bh2! Kd4 (if Ke6 8.Kxa5 Kd7 9.Kb5 Kc8 10.Kc6 and the King is cut off , the pawn will queen) 8.Kxa4 Kc5 9.Ka5 Kc6 10.Ka6 Kc5 11.a4 Kc6 12.a5 Kc5 13.Kb7 Kb5 14.a6 and the pawn will queen. ( Mike Fitch )

3... Kc4

4.Kc6 Kb3

Black can try another route to a8 but it will not be successful: 4...Kd3 5.Kb5 Ke4 6.Kxa4 Kd5 7.Kb5 Kd6 8.Ka6 Kc6 9.a4 Kd7 10.Kb7 the King is kept out and White wins.

5.Bc5 Kc4

6.Bd6 ...

The Kling and Horwitz continuation was: 6.Be3 Kb3 7.Bc1 Kc4 8.Bb2 Kb3 9.Kb5+-

6.... Kd4

7.Kb5 Kd5

8.Bh2! ...

The Bishop stays on the important diagonal b8-h2 to help keep the King out of the drawing corner of the board.

8... Ke6

Crafty found the earlier moves and now deviates with: 8....Kd4 9. Kxa4 Kc5 10. Ka5 Kc6 11. Ka6 Kc5 12. a4 Kc6 13. a5 Kc5 14. Kb7 Kb5 15. a6 Ka5 16. a7 Kb5 17. a8=Q Kc4 White now mates starting with 18. Qd8. Crafty 12.9 UNIX No endgame tablebases. (Valentin Albillo)

9.Kxa4 ...

White can safely win the pawn and get forward to stop the enemy King reaching a8.

9.... Kd7

10.Kb5 Kc8

11.Kc6 ....

and WINS

Rauzer worked out in his research the drawing zone in which the King has to be present to get to a8. He stated that: "White always wins if the Black King is cut off from the sector of the board bounded by the squares a8, h8, h6, f4, e5, d4,and a7"

The Black King once inside the drawing zone also has to get to the a8 corner in time. Rauzer showed in the late 1920's that the assessment of a number of classical studies was wrong. He demonstrated in the following position that White wins irrespective of who it is to move:

8/8/8/5KB1/p7/P4k2/8/8

Analysts up to then thought only White could win if it was his move.

I am now taking a short break, but will be back with a new position on SUNDAY 11th April.

HAPPY EASTER
