29...Nf2+??
Somehow I thought White's last move - he had captured a bishop on b5 - left the f2 square unprotected, allowing me to fork his king and queen. I guess I was partly right - I have indeed forked his king and queen, but, contrary to my great expectations, I was not winning his queen.
Indeed, after …
30.Rxf2
… White has an overwhelming advantage.
The game finished:
30...Qxb5 31.Be2 (the immediate 31.f5 is even stronger) Qa5 (not the best, but Black's game is lost, eg covering the d7 square with 31...Qe8 is met by 32.f5, when the engines' best line runs 32...Bf6 33.Bb5! Qf7 34.Bxf6 Qxf6 35.fxg6+ etc) 32.Qd7 Rf7 33.f5 (this is crushing) Bf6 34.fxg6+ Rxg6 35.Qf5! (the only move, but very strong) Bg5 36.Qxf7+ Nxf7 37.Rxf7+ Kg8 38.Rgf1 Qd8 39.Bh5 Bf6 40.Bxf6 Rxf6 41.R7xf6 1-0
Returning to the diagram, Black gets a big advantage with 29...e3, when ...Nf2+ is a real threat. White loses the exchange with 30.Bxg4 exd2, so Stockfish10 and Komodo9 come to give 30.Nc7, but 30...exd2! still leaves Black with the upper hand.
