I understand your concern, and remember perfectly what you are referring to,
however I'll add the following points:
- The TBs that might have caused problems were from a 3 CD set and truly
incomplete. It was missing many piece combinations however unlikely. This is a 9
CD set where the only missing combinations are ones in which Tiger (or any
engine) would find a mate in a fraction of a second.
- If Tiger were to reach one of the postions mentioned at any point of its
calculations, it shouldn't play any weaker. After all, it would be effectively
up some 20-30 pawns in its eval.
- Tiger has undergone significant testing on the machines at Convekta in order
to test the sets as well as some other functions used in Chess Assistant and no
problems of any kind have shown up in this time. The engine-related functions I
speak of are use of the TBs by Tiger, and use of the TBs by the GUI to
complement an engine that doesn't support them internally.
Personally, I wouldn't fill up more than a Gb of space on my HD to put in KQQQ
vs. K type combinations.
