Mate in 3
A problem by the late Greek Grandmaster of Composition Byron Zappas, which should provide straightforward solving.
1.Bc6 threat 2.Rd5+ exd5 3.Qxd5; 1...Bf3 2.Qh2 threat 3.Qxf4; 2...Re4 3.Rxb5; 1...Rf3 2.Rg7 threat 3.Rg5; 2...Bd3 3.Qa1; 1...Bc4 2.Sxc4+ bxc4 3.Rb5. Two neat variations in which rook and bishop each interfere with the other. There is an unfortunate strategic mismatch in that 1...Bf3 is also an obstruction, preventing the rook from guarding f4 from f3. Nevertheless, a pretty problem.
