THE FIFTH POSITION
White is on the move, and it is evident that he loses if he moves the man on 27 permitting black to reply 11-15. The only way to save the game is to sacrifice the man on 20 by 20-16. The following play would ensue.

Preventing 23-18
(5) … 9-6 (6) 27-31 6-2K (7) 31-27 2-6
White cannot save the piece and so he runs his opponent.

(10) 18-11 9-18
(11) 17-22 18-25
(12) 11-15 25-22
Drawn. White would lose by 21-17, as after (13) 15-18, 17-13; (14) 18-14, 25-22; (15) 12-16 he cannot gain the double corner.
The following has been suggested as a suitable problem to be called SIXTH POSITION.

DIAGRAM 107.—BLACK TO MOVE AND WHITE TO DRAW.
Black plays
(1) 7-2
threatening (2) 3-7 and (3) 15-11. White can prevent this only by
(1) … 24-20
Now 3-7 would only draw on account of 16-11.
(2) 2-6 20-24 (3) 6-10 24-20
Again 3-7 had to be prevented.
(4) 10-14 20-24 (5) 14-17 24-27
This time 24-20 would have lost, as Black would have replied (6) 17-13, 20-24; (7) 3-7, 12-8; (8) 15-11.
(6) 17-13 27-32
Avoiding 27-24 which would lose by (7) 3-7
(7) 13-9 32-27 (8) 9-14 27-24 (9) 14-18 24-27
Drawn. White has to watch 3-7 and to take care to play 24-20 at the right time so as to exchange 16-11 if 3-7 is played. At the same time he must beware of playing 24-20 when the Black Kings are on squares 15 and 5 or 15 and 13, as otherwise Black would reply 5-9, 20-24; 3-7, 12-8; 15-11.
