Go up one level in this thread

I don't agree fully with you, Gian-Carlo.

I think that getting unreliable main variations is a well known consequence of
any zero window search like for instance PVS or MTD.
The reason is that you will very often have moves in the PV which are just
sufficient to refute the preceeding move. In general you wan't have exact scores
neither exact variations.

I don't think that this effect has to be attributed to the hashing algorithm.

Regards, Uli
