White to move and checkmate in 7
Harder. Hope I haven’t overlooked something.
1. f4 e4 (avoiding fxe5 followed by Qf7)
2. Bc4 Kd7 (2. … Qxc4; 3. Qe8+ Ne7 [3. … Kd5; 4. Qf7+ Be6; 5. Qxb7#; or 4. … Kc6; 5. Rb6#]; 4. Qxe7 Kd5; 5. Qf7+ Be6; 6. Qxb7#)
3. Bxd5 Ba5 (preventing 4. Qf7+ Kd8; 5. Bc7#)
4. f5 gxf5 (else 5. c6+ bxc6; 6. Be6#)
5. Be6 Kc6 (5. … Ke6; 6. Qxe5#)
6. Qe8 Bd7
7. Qxd7#
This is just impossible. I can’t see it. Too difficult.
f4!
1. Rb6! wins material (threat Bc7)
1. f4! mates
