Kasparov was a sore loser all right, luckily he didn't lose that much so we didn't witness too many of his rants.These are not opening specific, but he also completely lost it when the best game award was given to Radjabov in a Linares, the game unfortunately being the game where he beat Kasparov with a knight sacrifice. He also has taken back a move against one of the polgar sisters and blatantly lied about to the arbiter when polgar explained what happened. He also accused Kramnik of avoiding a WC rematch where in reality it was him refusing to participate in a normal candidates cycle. He split the chess world by founding his own organization and caused total chaos for many years, which truly damaged the game. The list goes on.
He later delivered the flag to Topalov, who was a few classes higher in his ungentlemanlike behaviours, accusing Kramink by cheating, intruding his privacy by examining the video tapes of his time spent in his own private rest room etc.
I haven't read very much about the behind the scenes part of professional chess, but a few things are mentioned enough that I've picked them up. For one thing, Kasparov is not exactly known for losing gracefully. I remember some of his behavior towards the Deep Blue team too.
So my imagination is getting carried away after getting a tantalizing hint of an incident with Short. In Play The Open Games As Black by John Emms, the author discusses why 1. e4 e5 2. f4 exf4 3. Bc4 Qh4+ is not very good, despite how it might look to a beginner. He mentions a theme game in which the opening the players were forced to play was the Bryan Countergambit, in which Kasparov lasted all of fifteen moves and "was not a happy man at the end of the game". I've read a couple things about Short, so I imagine him bopping his head up and down singing "Rocking The Kaspah" while Garry loses control.
Does anyone know about his reaction to getting spanked right out of the opening like that? Any other amusing Elmer Fudd reactions from frustrated professionals?
