Hi Eric,

sorry, but I still donīt understand,
why do you need to take account of all this awfully complicated
ko - stuff in your tablebases?

Wouldnīt it be the simpliest solution 
not to store ANY ko-position at all!?

Your program then may use the super ko rule
or even the Japanese simple ko rules,
what you like better
(I prefer the super ko rule for computer programs,
 because I think there are too much ko situations,
 that would need a very deep understanding of Go
 if you use Japanese rules - this makes only sense for
 very skilled human players, who really understand such situations!) ...

But tell your program, 
that a position with any ko-forbidden move 
is not a "complete position" 
and therefore not stored in your TT -
thus when a ko comes up in a game
the program will have to search for the next available 
"complete position" without any ko defect! 
And this shouldnīt be too much a problem, I think ?!

Also this is what every Go player would try to do 
in ko - positions: only non-understanding computer programs
tend to loop as long as possible in ko circles,
a real go player would ever look for a finite solution
or (Japanese rules:) accept jigo ...

Thats just my idea of it.

Regards,
Stefan
