1.Qb5+ Kd8 2.Qb4 with the mating idea on f8, but then I saw that 2.Nc4 stops everything.
So yes, I think anon 2:03 is right,
2.Qb6 Qxe5 ( only move to stop mate since black was intending to play 3.Qd6+ Ke8 4.Nc6 and mating; Ex: 2…Nc5 3.Qd6+ Ke8 4.Nc6 Rd7 4.Qb8 mates; 2….Kf8 3.Qd6+ Kg8 4.Qd8#)
3.Nc6+ Kd7
(3…Kc8 4.Qb8+ Kd7 4.NxQ+ Kd6 5.Qd8+ KxN 6.QxR+ with an easy win)
Nb5
1.Nb5!?
1….Qxe5 and then what?
What can Black do after
1.Qb5+ Kd8
2.Qb6
?
I was thinking first of
1.Qb5+ Kd8
2.Qb4 with the mating idea on f8, but then I saw that 2.Nc4 stops everything.
So yes, I think anon 2:03 is right,
2.Qb6 Qxe5 ( only move to stop mate since black was intending to play 3.Qd6+ Ke8 4.Nc6 and mating; Ex: 2…Nc5 3.Qd6+ Ke8 4.Nc6 Rd7 4.Qb8 mates; 2….Kf8 3.Qd6+ Kg8 4.Qd8#)
3.Nc6+ Kd7
(3…Kc8 4.Qb8+ Kd7 4.NxQ+ Kd6 5.Qd8+ KxN 6.QxR+ with an easy win)
4.Nxd6+ Kc8
5.Nc6 and wins
I must admit, this was a tough one.
I like
1. Qf8, threatening mate next move at either e7 or d6. If
1. … RxN
2. Qe7+ and Black loses a rook.
