Disable?? Do you know the CB Tiger?

I don't think he has disabled anything. TBs must be installed and configured
manually, in addition to the install process. Furthermore, you can't expect
every user to have all the 5-piece tbs (not even that everyone know what tbs
are...). So I assume the Rebel Tigers have the same problem.

A top chess engine should *never* miss a mate in two. TBs or not, Nullmove or
not...

I'm afraid we must call it a bug IMO. But if you are satisfied with engines,
that need GigaBytes of data for a correct 3 ply search... it's your choice.

It's a chance to improve the product even further, to remove a problem. Valuable
information for the programmers and distributors IMO. I don't think they find it
ok to miss mates in 2 or things like that.
