I think that 32.fxe3 is the losing blunder of Shredder when 32.Qxe3 is the right
move(it is clear from the game that black has a clear advantage after 32.fxe3).

[D]2r3k1/1q3pp1/2bP2rp/1p6/5B2/pPR1p2P/P2Q1PP1/2R3K1 w - - 0 1

Deep Fritz needs 11:17 on pIII800(64 mbytes) to find Qxe3 and solves the fail
high at depth 16 with evaluation of +0.34 for white.
