I generally stop a rollout when its trial count reaches 62k. If the top plays are still close at that point, I am happy to call it a tie.

Here is one of those rare positions where XG produces an exact tie (to four decimal places). You can indulge your "style," and still defend your move as being the best in an XG rollout!
