This took me some time to figure out… 1.Re6 fxe6 2.Bxh6+ Kg8 looks tempting, but I couldn’t find a clear win for some time. If white could play Qxe6 he would mate, but how? The answer seems to be 3.Rb3! Qxb3 4.Qxe6 Kh8 5.Qf7. Now the knight needs to move to prevent Qf8, but then it’s Qg7#.
If white plays something like 3…Qa6, then 4.Rxb7 follows, and white still can’t recapture. So probably best for black is 1…Bxc1 2.Rxb6 Rxb6 and then for example 3.Nb5 and white is clearly better.
wow, this is pretty good one. hard to see it as black though.
1. Re6 ! fxe6
2. Bxh6+
if 2. .. Kf7
3. Rb3!
(if black Q does not guard e6, 4 Qe6#
if black Q protects e6, 4. Rab7 wins piece)
if 2. … Kf8
3.Rb3!
if 3… Qxb3, 4. Qxe6+ Kh8 5. Qf7!
threatening 6. Qf8#
if the black N moves, then 6. Qg7#
Rook to e6
This is very diffucilt.
