At first sight, it might seem unwise to break up the King row, when 9-14 could be played; but the advantage of holding the man on 13, instead of allowing him to complicate matters by 13-9, more than counterbalances the disadvantage of moving a back man.  Black could also play (10) 2-6, but this admits of the following strong attack:  (10) 2-6, 27-23; (11) 4-8, 23-16; (12) 12-19, 32- 27; (13) 9-14, 27-24; (14) 3-7 (8-12 would lose), 22-17; (15) 14- 18 (again 8-12 would lose), 17-14; (16) 10-17, 21-14; (17) 1-5, 31-27; (18) 6-10, 24-20; (19) 10-17, 26-22; (20) 18-25, 30-14; (21) 7-11 (Probably the only move to draw—­8-12 would lose on account of 20-16).

(10) ...            27-24
(11) 4-8            32-27

22-18 could also be played.

or 22-17 or 24-20.

(13) 3-7            23-16
(14) 12-19          22-17
(15) 7-11           26-23

31-27 would lose through (16) 8-12, 26-22; (17) 11-16, 24-20; (18) 19-24, 20-11; (19) 24-31, 11-8; (20) 14-18.

(16) 19-26          30-23
(17)  8-12          24-20
(18) 15-18          23-19

20-16 cannot be played on account of (19) 20-27, 16-7; (20) 2-11, 31-24; (21) 12-16.

(19) 11-15 20-16

White can, of course, draw here by 31-26; but 20-16 also draws in spite of Black’s seemingly invincible elbow.

Black White

(20) 15-24 28-19
(21) 2-7 31-26
(22) 18-23

If 18-22, White draws by 19-15; (23) 12-19, 13-9.

(22) ... 26-22
