White. White to move and draw. Tho solution, which Mr. W. Unit,lie happily describes as "surprisingly simple and singularly beautiful," is as follows :— 9- 0-2 2- Go 0- 22- 6 6-2 20—22 18-23 23-28 2U-3I 30—20 etc. and White draws by simply playing the nle:e to and from square '2, leaving Black to force tlie piny.

The mail on 21) and 21 sre necessary to tlio draw," and must not b' moved until Black lias forced an exchange. The defending player must have the move. (c) The crux of the situation. Mr. Prinkwatcr played 20—10, allowing Black to draw. G'ahrNo. 140— Switcher." Mr. J. M. Adams, of Strabine, writes to the Liverpool Weekly .Mercury tint tho recently pub llshed GKanitdo* of " I'eiterson's Urawbrldw" form an unusually interesting study in draughts strategy 11" adds that the pulley of " masterly inactivity" might well he adopted more frequently than it is. Ik-re is an example "f a "Swiieher" game from " l.ea's Guide," in which Mr. Wylllo unnecessarily throws the onus of development on the weak side ;- 11-15 18-22 11-10 10-15 10-12 -24 21-17 20-17 20-11 17-13 27-32 8-11 0-13 15— 8—22 8-11 12- 8 32-28 25-21 21-211 82-28 27—-.'3 11-10 30—20 a 8— 3- 8 4- 12— 211-11 22-25 17— 20-25 21-20 13- 9 f—lo 211-22 10-17 1- 0 0- 9 15-18 8- 3 24-27 21-14 23-21 2H-24 24-1!) 10-20 31-24 0-10 IS—22 9-18 18-27 3- 8 23-19 22-17 25-18 23-14 And Black wins. Noil!, (a) White, letting " bad enough alone," should simply play 11-8. Like Patterson's 2-6 this is a dull, aggravating sort of move. Hut it draws. Nay, more; if Black tries lo coma out, it wins. For example: -21 -37,31-24, '.'8 -19,14 -111, 5-14,10 -7, and White wins. In every variation White has the easier came. Thus if 2—7, B—3, etc.; and if 28—32, 8-11, 32-27, 11-15, Otc.
