Here is a sample drawing line for white: 1. Bxd4 cxd4 2. Kg2 Ke7 3. Kf3 Kd6 4. Ke4 Kc5 5. Kf3 e5 6. Ke4 Kd6 7. Kf3 Ke6 8. Ke4 * Bxd4! plugs up the entry point for black's king. In the actual game black penetrated and won. >R7/1P4k1/8/5b1r/6r1/3p4/3R1K2/8 b - - [Event "40/40 PII-400 256MB"] [Site "Cadaques"] [Date "1998.10.15"] [Round "?"] [White "Fritz 5"] [Black "Junior 5"] [Result "1-0"] [WhiteElo "?"] [BlackElo "?"] [ECO "A22"] 1. c4 e5 2.

Computers are such ferocious fighters that they sometimes don't know when to be satisfied with a draw. > >What is the correct answer [with pv]?
