Bb5+ Ke7 {One of those sacrifices like 4.xf7 in the Petrov where it is impossible to analyze it till the very end. White has only a pawn in return for his piece but the black king finds it very uncomfortable in the center.} 11. Qe2 {Here I thought for a long time, 11...f6 seems evident but 11...f6 was also tempting, it had a very ugly look but over the board I could not find a direct refutation. Further analysis shows it is not so easy to refute anyway.} f6 (11... Kf6 {Here are some of the possibilities that were considered right after the game} 12. Bg3 $1 {A extremely difficult move to meet over the board, the saving resource d3+ does not work anymore and the f-file is cleared to recapture with check on f3 after f3 which is coming with great strength.} (12.
