I seem to have found it.

I have created a function that converts the hashtable score to a search score (basicly adjusting for checkmates)

Unfortunately, I didn't send in the found hashtablescore, but a value initialised to +/- inf (depending on upper or lower bound), meaning it would get a hashtable cutoff with a checkmate score, any time the depth was sufficient (but never when in PV).

That will wreck your search. The only thing I don't understand is that it was able to play something resembling chess at all.

Thanks all,

Tony
