WHITE to play and mate in two moves: solution next week. Solution to last week's problem by Barnes: Kt x P, no threat. 1 . . . K x Kt; 2 Q-Q 8. 1 . . .

RxQB P; 2 R (B 1)-Q 1. 1 R any other; 2 R-B 4. 1 ... Kt x Kt; 2 R-B 4. 1 .. Kt any other; 2 R (B 1)- Q 1. Attractive 'correction theme' problem. Random rook moves lead to R-B 4 mate: 'correcting' to avoid this allows R-Q 1. With Kt moves the two mates are neatly interchanged.
