CHESS SOLUTION

Solutions to Chess Tasks an p. 879.—(1) 1 P-K 3, P-Q R 4; 2 Q-R 4, R-R 3; 3Q x QR P, P-R 4; 4 Q x B P, R (3)- R 3; 5 P-K R 4, P-B 3; 6 Q x P ch, K-B 2; 7 Q x Kt, Q-Q 6; 8 Q x Kt, Q-R 2; 9 Q x B, K-Kt 3; 10 Q-K 6 stalemate (S. Loyd, 1866).

(2) 1 P-Q R 4, P-Q B 4; 2 P-Q 4, P-Q 3; 3 Q-Q 2, P-K 4; 4 Q-B 4, P-K 5; 5 P-R 3, B-K 2; 6 Q-R 2, B-R 5; 7 R-R 3, B-K 3; 8 R-K Kt 3, B-Kt 6; 9 Kt-Q 2, Q-R 4; 10 P-Q 5, P-K 6; 11 P-Q B 4, P-B 4; 12 P-B 3,.P-B 5 stalemate (C. H. Wheeler, 1887).

(3) Positions given in Forsythe notation, i.e., start at White's q R 8 and put pieces as indicated line by line, numbers indicating gaps to be left: capitals are White pieces, small letters Black, N= knight. Thus 2 P 3 n I means two spaces, White pawn, 3 spaces, Black knight, ohe space.

(a) —4 N I r 1—P 2 PK 2 P-8-1 PlkBQ 2— 2 R 5-3 N 4—B 3 P 3-3 R 4. (J. C. West, 1880.) 47 mates, (b) --2Q 4 R-4Q 3—N0401-3 k4—Q 4Q 1 R- 2 Q 5—p 3 Q 1 K 1-1 Q 5 B. (W. A. Shinkman, 1886.) 99 mates.

(4) Black's moves must have been 1 P-K 3 or K 4, 2 Q-11 3, 3 Q x P ch (daring!). 4 11-K 2 mate.

Equally good alternative solutions to 2, 3 (a), 3 (c) are 'mown; I have given earliest one in each case.
