1. Ng6+ Kg8 ( 1. … hxg6 2. Qh3+ Kg8 3. Nh6+ Kh7 4. Qxe6 )
2. Nh6+ gxh6
3. Qxe6+ Kg7
4. Nxf8
1. Ng6+ hxg6 2. Qh3+ Kg8 3. Nh6+ gxh6 4. Qxe6 sorry
If there is a mate here, I can’t find it, but I saw the immediate win of material:
1) Ng6+, hxg6
2) Qh3+ (staying on the c8-h3 diagonal), Kg8
3) Nh6+ gxh6
4) Qxe6+, winning a Queen for two Knights. After K moves, White can simplify further:
5) Bxb6, Rc6,
6) Qxc6, Bxc6
7) Bxd8, and White is a Rook ahead, with the a5 pawn loose.
Nevertheless, my instincts tell me I’m missing something. Does anyone see something better?
In light of that continuation after 4.Qxe6, black might do best to decline the knight on the 3rd move:
1. Ng6 hg6
2. Qh3 Kg8
3. Nh6 Kh7
4. Qe6 Rc6
5. Qg4 hg6
Limits the damage a tiny bit, but still a decisive edge to white. One might want to look into 5.Qf7 in that line- it looks interesting to me at a glance:
5. Qf7 Rf7
6. Nf7 Be7
7. e5! and black will lose more material- almost as much as in the line where white retreats the queen to g4, but I am far less certain of this sideline without putting in a lot more time on it.
Ng6+ wins.
Puzzles for Alena, or any who wish to try them. I have been, in recent weeks, just been working through this own blogs puzzles from 2011 and now 2012. As one can probably see, the difficulty level was higher then- puzzles like ones that follow were routine sorts of puzzles in those days. I haven’t seen a puzzle at these levels here in several months now.

Here is the solution for the third puzzle. The first move is obvious if white wants to win. It was difficult to find the seventh move .

4. b7 Rg2
5. b8=N+ Kc7
6. Nc6 Rg8

12. exf4+ Kf5
It’s a winning position for white.
Well done. This was a difficult problem. Link to the previous time it was posted here: Link
Mate in 4 was much easier than mate in 3 for me.
