This maneuver, as will be evident from a careful study of the position, is possible only in case White has the move.  If Black has the move the ending is a draw.

Black White

(1) ... 23-27
(2) 28-32 19-23
(3) 32-28

Black cannot play 12-16, as 27-24 would win a piece.

(3) ... 27-32
(4) 28-24

Again 12-16 is not possible on account of 32-27 winning a piece in three moves.

(4) ... 23-18

Diagram 94.

White played 32-28 Black would exchange by five 24-19 and draw the game.

In the position of the Diagram Black has the choice between 24- 20, 12-16, 24-19 or 24-28, but he loses, no matter what move he makes as demonstrated below.

(A) (5) 24-20 32-27
          (6) 20-16 18-15
          (7) 16-20 15-18
          (8) 12-16 18-15

(B) (5) 12-16 18-15

Now Black cannot play (6) 16-19 because of the exchange 32-27; (6) 16-20 would also lose quickly through 15-18, (7) 24-19, 32- 28, (8) 19-16, 18-23.  The best try is (6) 24-28.

Against 15-18 Black would now draw by (7) 16-19, 32-27; (8) 19- 23.

The only way to win is

(6) ... 15-11

after which Black can do no better than

(7) 16-19          32-27
(8) 28-32          27-31
(9) 32-28          11-16
(10) 19-24          16-19, etc.

(C) (5) 24-19 32-28
          (6) 12-16 28-32
          (7) 19-24 18-15

and White continues as shown before.

(D) (5) 24-28 18-15
          (6) 28-24 32-28
          (7) 24-27 15-18
          (8) 12-16 28-32
          (9) 27-24 18-15

and wins as before by 15-18 in reply to (10) 16-20 or 15-11 in reply to 24-28.

THE SECOND POSITION (See Diagram 95)

White’s advantage is that he can crown his two men while Black remains with only one King and two men.  The reason why Black cannot use his two men to advantage is that they are pinned on the side of the board while White’s men are located in the center where they have much more mobility.  All the same White must have the move in order to win, just as in first position.
