I think the losing mistake of crafty was 54.Qxf5.
Junior5 and fritz5 want to play 54.Qxf5 but reject it after a short time.
They prefer 54.Qc6.
The evaluation of Qc6 after 10 minutes is 0.00 by both programs.

Junior5 evaluated the position at move 36 as 0.89 pawns advantage for white
at depth 16 and wanted to play 36.Bd3
