[computer-go] KO in Hashtable-UCT?

So far the SuperKOs I have found where a "round-trip" of KOs.

Okay.

No. I assume the game is over. As there is usually no reliable method for 
counting territory I use the difference of the captured stones as a - first 
approximation - for the evaluation. If e.g. both sides have captured - in 
the whole game - the same amount of stones, the eval is 0, but white wins 
due to Komi.
At least for significant differences in captures this is true. MC-Runs are 
also stopped, when one sides leads in Capture by a large margin.
Depending on the margin it produces only a negible bias.

The cycles I have found so far are balanced. Each side captures in turn 1 
stone.
