PostPost subject: preprocessing by houdini1.5    Posted: Tue May 22, 2012 5:30 am Reply to topic Reply with quote
It seems that the evaluation of houdini is dependent on the root position

before Qxe7 houdini evaluates the position as at least 1.8 for white at depths 20-24

After Qxe7 Rxe7 houdini does not get the 1.8 number at depth 20-25

I wonder if this preprocessing is a bug or some intended behaviour and if houdini2.0 shows the same behaviour.
