Problem #7

The last problem was more than 2 months ago. Time for a problem!

I played this game earlier today. I have reached an obviously winning position, but I had to definitely take my time there to find the winning path. It's actually a mate in 6! (Well, technically it's mate in 7 given that White has Qxh2+ at some point, delaying the mate for one more move, but we all know in practice that he wouldn't play that move). Note that the mate in 6 is the only mate in the position, as confirmed by computer analysis.


White to move


To see the solution, just highlight the hidden text below.

====================
Solution:

20. Qg6 Kg8 21. Qf7+ Kh8 22. Ng6+ Kh7 23. Ne7+ Kh8 24. Qg6 1-0. White will play Qh7# either next move or after Black throws in the sorry 24. ...Qxh2+.
