You are incorrect that the following heuristics in random games
lead to
finite game length:
* no eye filling
* no suicide
* no simple ko violations
Consider two eyeless chains with 3 ko's connecting them... Two
taken by
black and it's white's move. Filling the one ko it has is suicide.
It must
take a ko. On black's turn, it can't fill a ko due to suicide and
must take
a ko. The cycle repeats infinitely.
If passing is always legal and two passes terminate the game, then the
expected game length is finite no matter how you limit the other
options. If you forbid passing early then I suppose you have good
reasons for that, but it could be the reason why you and Don reached
different conclusions.
Does anyone allow passing at random in their playouts??? A game
stopped from two premature passes is tough to score, if not completely
meaningless.
Once upon a time, I thought the simple playout rules led to finite
games. Infinite cycles are really rare and went unnoticed by me for a
very long time.
