Bill mentioned in an earlier post that Chicago FM Andrew Karklins has beaten about 20 grandmasters. Here is one of those wins, against the super-solid American GM Maxim Dlugy. (Is he one of those "Maxims of Chess" John Collins wrote a book about?) Note that Karklins' offbeat 5.Bg5!? already set the trap 5...h6?? 6.Nd6+! winning the queen. Dlugy blundered on move 10, falling into another unusual queen trap. After winning the queen, Karklins was not content to quietly exploit his material advantage, but continued to play the most incisive move at every turn. I like how in the final position, Black could play 21...Rxd1 mate - if only it were legal!
