Nc6 is chosen, but only after 34 minutes, later Nxe5 comes back. In an earlier result, Nc6 was chosen much sooner. Why this could have happened, only thing I can think of is maybe not all hashtable results were gone. I have no learning switches so there should be no position learning at all. There is no Clear hashtables Always switch in Betazoid, so that could be a partial cause. Maybe I forgot to set 'Clear hash' under Advanced properties that time, when loading a new personality. What I said then in my post before above about the effect of different hashtable size also does not hold, as that referred to testing this position with 40 Mb HT. But the 28 MB results are not reproducible. Conclusion then that maybe Betazoid T90 will not differ much from Betazoid T8 and could be worth further testing. I would rather have some version that does not play Bc5, but that may not be so easy..
