both players are using computer to do home preparation for this match, and both are d4 players.(from first game to the latest game)
Topalov is not FISCHER who always played the first move e4 before the match against Spassky but he did not play a single e4 game during the whole match. also FISCHER is the one who forfeited the 2nd game.
one more thing, FISCHER was playing against the mighty Russan team, and he always accused the Russan was cheating.
