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.
