Apr-21-09  Bears092: how about 17. Bxe5 followed by 18. Bxb5

is there anything in that?

Apr-21-09  Dr. Funkenstein: Wow, great underpromotion at the end that somehow both stops the threatened perpetual check and threatens mate at the same time
Apr-21-09  braimondi: Very nice pawn promotion ;)

  luzhin: In fact Akopian could have immediately played the winning king march (followed by the underpromotion) by playing 54.a7 etc. But who can blame him for using Q checks to spend more time to consider the position? Karjakin's 22...bxc4 looked very odd: after that his position was totally rigid.

  luzhin: Bears092: Unfortunately after 17.Bxe5 Bxe5 18.Bxb5 axb5 19.Qxa8 Qxa8 20.Nc7+ Kd7 21.Nxa8 Kc6 Black will capture the wandering Knight and his two extra Bishops are much better than White's extra Rook.

  JointheArmy: Nice underpromotion that forces Karjakin to resign.
Apr-21-09  Augalv: Commentary at: http://karjakin.blogspot.com/
Apr-22-09  arsen387: <The representative of the older generation (who had also been a young star someday) gave a perfect lesson to the young and brilliant opponent. Maybe Karjakin simply underestimated Akopian and decided to play against him beyond the acceptable risk. Perhaps judging Sergey’s novelty 16…b5 by a single game is irresponsible, especially considering that ‘Karjakin-made’ opening ideas are usually of the highest quality. However, Akopian used simple and logical means to parry Black’s threats, and obtained a lasting advantage. Vladimir converted this advantage in a classic way. The excellent 31.Qc7! deserves special attention. In the endgame White sacrificed a bishop (51.Qb5!) and advanced his passed a-pawn. Here began the most interesting part! Usually players always queen their pawns without giving a proper thought to underpromotion. However, in this case the automatic 71.a8Q? only led to a perpetual check. By promoting his pawn to the knight, Akopian defended his king and created irresistible threats to the opponent’s monarch! An excellent victory!> GM Shipov, http://nalchik2009.fide.com/round-6...

really very beautiful win by Akopian, the best of the tournament so far, at least for me

Apr-22-09  Alphastar: 78. a8=N is excellent.

Karjakin's 22...bxc4 looked very odd: after that his position was totally rigid.> The other move was 22...Qxc4. However, after 23.Qxg5 Bxd5 24.Qxd5, White won a pawn too. As a matter of fact, it should be noticed that the natural move 21...Nc4 loses a pawn.
