  Honza Cervenka: 17.Qe2? was a slip in already growing time pressure. 17.g4! Rf6 18.Na4 Qd4 19.Rcxf2! Qxd1 20.Rxf6! Bxg4 21.Rf4 Qxf1+ 22.Rxf1 was correct. I still cannot believe that 12...Qxb2 is sound but if it is viable option for black after 12.Bf3, then 12.Nd5 would have been better.

I was wondering what move in this game diverged from your opening repertoire.

Mar-06-24  vonKrolock: <Honza> The line you pointed out is fantastic (the combination starting with g2-g4 as a key: it would be thrilling to watch this OTB ... I was seeing this other line - perhaps more intuitive - but Black recover the piece with 22... Bd1: 17. Rfxf2 Rxf2 18. Na4 Bg4 19. Qa1 Qd4 20. Qxd4 Rf1+ 21. Qg1 Rxg1+ 22. Kxg1 Bd1! 23. Rb2 Bxa4 24. Rb7 with just some compensation for the minus in Pawns.

  Honza Cervenka: <FM David H. Levin> 6...Nh6 was a surprise for me. I faintly recollected a game of Spassky, where he played that with idea of quick f7-f5 (it was Furman vs Spassky, 1957) but that's all. From that point I had to invent all the theory, and that was very time consuming.

  perfidious: The game mentioned by <Honza> was annotated in Cafferty's work on Spassky in the 1970s.

  Honza Cervenka: During the game I was considering possibilities like 7.h3 and 7.Be2, 9.Qd2, 10.Bxd4, which I dismissed due to 10...Nxf5 11.Bc5 d6 12.Ba3 Nfd4, which I did not like over the board, and the longest contemplation was after 11...Qb6, where I went into deep calculating of possible consequences of greedy Qxb2 after eventual 12.Ne4, 12.Nd5 and 12.Bf3. I was considering also 12.Na4 Bxf2+ 13.Kh1 Qd4 14.Bg4 Qxd1 15.Raxd1 Rf7 16.Bf3 Bh4 17.Bd5 but there was nothing more than draw after 17...e6 18.Rxf7 Kxf7 19.Rf1+ Ke7 20.Nc3 exd5 21.Nxd5+ Kd6 22.Bf8+ Ke5 23.Bg7+ Kd6 etc. Another long deciding was between 15.Rc1 and 15.Ne4, which we both with my opponent heavily analysed in post mortem after the game. That is why I had just 14 minutes on the clock in the 17th move (tempo was 100 mins / 40 moves + 30 mins to the end of game without any increments). My opponent was in time troubles as well, though a bit less severe being only some five minutes better on the clock.

  Honza Cervenka: <vonKrolock> In your line 17.Rfxf2 Rxf2 18.Na4 Bg4 white can play 19.Qg1, and it seems to be better than 19.Qa1.
