Easy find. Setting up Mate in 1 with a King move just results in a quick fork and a loss and a non-check rook move does the same. Then you discover you have no follow-up checks so the natural move is promotion but then you face perpetuals in the middle of the board. The only remaining option is to deliver another check with the sacrifice and it becomes clear that promotion now sets up the discovered check, so there's no perpetual check. Then it's just a matter of running down the relevant lines.

Yep, that's beautiful

Found it in about a minute although my mate is in 10, not 9. I went 5 Qh1+ Ka2 and now 6 Qd5+ is one move faster, but I went 6 Qg2+ Ka3 7 Qa8+ Qa4 8 Qf8+ Ka2 9 Qf2+ with mate next move. It's pattern recognition. I have seen thousands of positions with Q and K vs Q and K (with or without more material on the board) patterns before. You have to know some queen endgames that can arise from pawn endgames.

Thank you!

That’s a brutal checkmate very smart…. Very beautiful 😂

What a move!!, amazing..

I merely suspected the solution but did not analyze, it is late in the night, I am looking the Candidates but I feel sleepy😂

Gotta love a sham sacrifice that is also a zugzwang!

The lesson I took away from this puzzle is that with queens on the board an extra piece’s influence can be negligible. The strategy of exchanging when you have material advantage is probably even more relevant for queens.

Excellent and brilliant as always... You are just excellent...Thank you very much and God bless you

This is a beautiful study! It is a shame that the name of the composer is elusive. The problem is not in Die Schwalbe PDB or in YACPDB, both public online chess problem databases. GM Igor Smirnov has also covered this study, reflected horizontally, on KZread, and he also does not mention an author. Where did you find this study?

This is etud of Kantorowich. I know

Solved it

i used to think the word zugzwang was chinese

What if black Queen moved to C1checks white king, white king moves putting black king in check then black king moves to B1 possibly leading to stalemate.

Not mentioned in this video, but white still wins! (4. Qh1+, Ka2; 5. Qg2+, Ka1 or b1; 6. Qb2#)

It is basically symmetric, coming from 'a' file to mate on a2 or second rank to mate on b2
