Checkmate in 7
About Author
I found a mate in 6. This probably means I overlooked something.
1.Bxc5+ bxc5
2.Rxe6+ Kf8
3.Qf6 Qxe6
4.Rd8+ Qe8
5.Qh8+ Ke7
6.Qxe8#
3… Rg8 perhaps
Anon @ 6:36 you’re on the right track and your line is even shorter. The link to the original game and solution: Checkmate in 7.
I could find it only after more than one hour thinking, but I was just looking to the original screen, no tips and no piece moves.
Anon @ 6:36
1 … bxc5 is actually mate in 5
(2.Rxe6+ Kf8 3.Qf6 Qxe6 4.Qxh8+ Ke7 5.Qd8#)
1 … Rxc5 prolongs mate 2 more moves
My computer points out the following beautiful line:
1. Rg6 Nd7 (other moves don’t prevent mate)
2. Qf6+ Nxf6
3. ef Kf8
4. Bxh6+ Rxh6
5. Rxh6 Kg8
6. Rd4 and mate follows
