You are right. Looks like my solution is not perfect, but it works good enough. I have seen trouble, before I implemented it, because the transposition table identified the same position in different situations. My solution worked, but, as you say it may not be perfect. Anyway, it is good enough for ko and my version of superko is a simplification restricted to the last 8 moves. Basically, triple ko and double ko of a group with one eye are the only superko sequences I have seen in serious games. I though it was good, now I have added a remark to the source code just in case some weird behavior appears. Thanks.
