Re: [computer-go] transposition-table and position-repetition

I think what you describe is a general case of a well-known specific
problem. And that is that sometimes the same position can be reached in
different ways where one ends in a ko-capture and the other doesn't. This
can result in incorrect results because the number of legal subsequent moves
is different in the positions that otherwise look the same.
 The solution you described is probably formally the correct way to solve
it, but as you already noticed, not very efficient.
The problem is known in the literature as the
"Graph History Interaction" problem.
