Ugh. I should be sleeping. Instead, I'm apparently up doing this. Here we go:
ResponderExcluir1. Rxe5+ fxe5
2. f6+ Kxf6
(2. ... Kf8
3. Rd8# )
3. Qf5+ Ke7
(3. ... Kxg7
4. Qg5+ Kf8/Kh8
5. Rd8# )
4. Qxe5+ Qe6
(5. ... Kf8
(6. Rd8# )
5. Kf5+ Ke8
6. Qxc7 Qxa2+ (only option, in desperation)
7. Kxa2 b3+ (more desperation)
8. cxb3 Kf8
9. Qc8#/Rd8#
(8. ... f6
9. Rd8# )
Not too much variation, as everything is extremely forcing, but if I missed anything, let me know. :)
ResponderExcluir1. Rxe5+; fxe5 (If Kf8; 2. Re8#/Rd8#)
2. f6+; Kxf6 (If Kf8; 3. Rd8#)
3. Rd6+; Qe6 (If Ke7; 4. Nf5+ and if Ke8; 5. Qg8#, alternately if K f8; 5. Rd8#)
4. Rxe6+; fxe6 (If Kf8; 5. Re8#)
5. Qxe6+; Kd8/f8
6. QG8+; Kd7/e7/f7; Qxh7... and it's easy for white
what about
ResponderExcluir1. Rxe5 fxe5
2. Qg5 Kf8
3. Rd8 mate, it looks much more forcing and much faster, or am i missing something?
@Piotrekp1: Probably due to 2...f6
