Unfortunately Sjeng's depth was only 6 when it did the losing blunder.
I guess that the main problem is that the celeron does not run at stable speed
and it got tired at move 33.
Note that even without 33...Bd7 white has a good chances to win the game but the
task is not simple but I think that the natural thing to do after seeing a
surprising result is to check if there is no problem in the game.
