My engine wants to play the questioned move after about 5s and keeps this move
for half an hour. Ok, that doesn't mean anything as my engine is very weak. But
more important is that several other engines think that 36. axb5 is one of the
better moves, Hiarcs, Junior, Shredder and Fruit (to name just a few) consider
this move to be the 2nd best move in this position. So I don't see a reason why
this move couldn't be played by Deep Blue.
