Re: Hash result futility pruning

Hash table scores are unreliable due to the nature of AB. In the 90's for a long time I had a hash table reduction if the hash table score for a position went down with 0.50 or more. Much later with much better hardware (more games) it became clear it was an unsound idea. Reply to self - I retried ...

MG | EG experiment

I created a tool that creates reasonable MG/EG PST's from a PGN database, nothing special so far, except if it splits MG and EG into 2 parts. Definitions: MG1 - for the opening and middle game with queens; MG2 - for the middle game without queens; EG1 - for the regular endgame EG2 - for the late end...
