Kasparov, Short play to a draw London- Garry Kasparov and Nigel Short played to a draw in the second game of their breakaway chess championship yesterday, as the challenger again appeared unsettled by the clock. Short playing white built up an early advantage but it slipped away when both players ran up against the two hour limit for finishing 40 moves. Kasparov leads the 24 game match 1 1/2 to 1/2. The third game is tomorrow. FIDE, the world chess federation, is sponsoring its own championship in the Netherlands between Anatoly Karpov and Jan Timman. A draw in that match yesterday left the two players tied at 1 1/2.
