1. Re8+
a) 1. …, Bxe8 2. e6+, Kg8 3. Nf6+, Kh8 (3. …, Kf8 4. Bb4#) 4. Nxe8+, Kg8 5. Nf6+, Kh8 6. e7 wins, e.g. 6. …, Qh1+ 7. Nh5+ etc.
b) 1. …, Qxe8 2. e6+, Kg8 3. Nf6+, Kf8 4. Bb4+, Qe7 5. Nxd7+, Ke8 6. Bxe7, Kxe7 7. Nc5 and wins, e.g. 7. …, a5 8. Kg5, a4 9. Kf5 and the knight is free to take care of the a-pawn.
But I have the feeling I am missing something…
In line b, black can play 7. … Kf6!
Then the white king needs a too long walk to protect the pawn on e6.
Don’t know about the solution yet for white. But white has to do something about it.
Something like
7. … Kf6 8 Kh7 a5 9. Kg8 Ke7 10. Kg7 a4 11. Kg6 a3 12. Kf5 a2 13. Nb3 Ke8
seems a draw
Hm this ending is winning also winning. 14. Kf6 Kf8 15. e7+ Ke8 16. Na1
7. …, Kf6! that’s it Brian! Gives the study a nice finishing touch.
Seems like a draw
1.re8 bxe8 2.e6+ kg8 3.nf6 #
But 1. … Qxe8 …. again seems like a draw…
