    Your name is Anna Muzychuk and you are one down with two games left against your upstart Chinese opponent who has just played 13...b5. Do you feel lucky? Apart from feeling lucky to be Anna Muzychuk, that is?

    There is no cure for leftism. Its infestation of the host mostly diminishes with age except in the most rabid of specimens.

    White played the sacrifice and black was smashed. (Actually 21.Qxe6+ would have ended the game several moves earlier.) The smashing method involving a second piece sac in the centre is unusual.

    13...b5?? enabled the sac by both unprotecting the knight on c6 and blocking the queen's defence of d5, thereby allowing 17.Nxd5 to work (if black takes back, white will take on d5 and c6 then swing to g6 and all over). Other 13th moves by black would have avoided this.

    13... b5 might make it easier for Anna to find a win but other moves on the Queen side would be blunders too. The weakness of the c6 knight was not very important as 17. Nxd5 was not the only move to continue the attack (17. Qe2 seems even stronger). I think Tan didn't have to keep the knight protected - she should have prevented the Bxh7 shot in the first place. Bxh7 became possible only after 13. h4, so that the *h* pawn was ready to recapture the bishop on g5 opening the h file. Tan didn't pay attention to that strong pawn move.
