Searching White's 25th move Fritz 5 sees the problem with f4 at 14 ply. Fritz
scores the postion as -0.34 for White picking Qc1 as the best move. Qb1 is next
scoring -1.47 (14 ply).

Searchin White's 26th move -- Fritz drops f4 at 11 ply in favor of Rxb7. On my
AMD K6-2 350 MHZ this takes less than 30 seconds. Bg2 is selected at 12 ply in
about 80 seconds (with several other windows running, I'm listening to the
Yankees-White Sox at the same time). At 13 ply - Bg2 -0.13 in 2:20. This would
have been found at the games' time controls. Also at 13 ply Rxb7 and f4 both
score -2.94 by Fritz.
