Wow!

Just had a mistake of mine corrected in a 960 game. Who can find what the analysis engine identifies as the best move?

nice one

thanks for sharing

I must try a lot until I found it, but then it is clear.

My current reading is focused on Victor Henkin, 1000 Checkmate Combinations, which was reissued in paperback last week. Naturally, I found the correct answer instantly and only had to spend half a minute checking for unseen consequences.

In the heat of battle, however, vision is not as clear as when someone presents a puzzle.

the square c3 looks inviting for Black's queen

It does, but the justification is rather complex. For example, 17. fxe4 Qc3+ 18. Nd2 has sacrificed one knight and a knight and a rook are hanging. But there is a discovered attack sacrificing a second knight to win the queen, hence 18. Kd1 instead.

It is mostly about mate and winning the queen. Both rooks are winnable by forks in different lines, but only one gets taken in the line that is least bad for white. At the end of this diagram white gets two pieces for a rook and two pawns, but the engine likes black a lot.
