Kamsky's father, Rustam - whose little contretemps with Nigel Short made the headlines in a PCA qualifying match last year - has already made his mark by sending home Gata's second, Alexander Shabalov, after another squabble.
In the other match, Boris Gelfand and Anatoly Karpov are level at 1-1 after two draws. The spirited nature of the play may be judged from the fact that both games ended in perpetual check.
The first game suggests that Karpov's Caro-Kann will be severely tested over the next two weeks. Playing the system that Nigel Short used with success against Karpov two years ago, Gelfand met a prepared response in 6...cxd4 and 7...Ne7.
Black's idea is that after 8...Nbc6 9.Nxf5 Nxf5 his game develops without problems. Gelfand's 9.Bb5! was the correct response, giving up White's bishop instead of taking Black's. After 11.c4! Black's position was looking cramped.
Karpov solved his problems imaginatively with the ugly looking 12...dxc4! freeing d5 for his knight. His 16...c5 precipitated a crisis by forcing Gelfand to sacrifice a piece.
At that stage, both players must have seen clearly to the end of the game. 19.e6! breaks open Black's defences and 22.Bc3! lures the knight offside. Black must take the draw since 23...Ke7 24.Rfe1+ Kd6 25.bxc3 leaves his king at the mercy of White's queen and rooks.
