AS I write, the important tournament at Sarajevo is getting under way. From a British angle, the participation of Michael Adams and Nigel Short is of interest. However, from the global point of view, the focus of atten- tion will be the duel between Garry Kasparov and Alexei Shirov. As we know, Kasparov will defend his world title against Vladimir Kramnik in London over October and November. There are those who believe that Shirov is the player who should have been given a crack at the champion. Sarajevo will tell. Over past form, though, Kasparov has been dominant, winning nine games against the unruly Latvian genius, while los- ing none. Here are two samples.
