So far the best example I found is 40... Bc7 in the 3rd game. DB switched to it
in 83 seconds.

Deep Blue prefered Bc7 with a score of +0.10 when the alternative dropped to a
0.00 score. So adopting Bc7 depended on evaluating it as a slight plus (not
logically, because black is slightly behind after returning the pawn, and next
move DB's score drops to minus right away. DB seems to have inconsistent
evaluation here).

In order not to make this test dependent on fine points of evaluation, the
question should not be "do you find Bc7 ?", but "Do you evaluate do-nothing
moves as draw or worse ?"
