White must he careful not to stalemate the Black King. For instance, if
Black were to play here 15. ... K to R sq., White could not play 16. B
to K B 5; but must play 16. B to K 3, K to R 2; 17. B to B 5: ch., K to
R sq.; 18. B to Q 4 mate.
16. B to K 3: ch. 16. K to R 2
17. B to B 5: ch. 17. K to R sq.
18. B to Q 4, checkmate.
