Your idea is more in the spirit of MC, I like it. Another idea is borrowed from my first reasonable MC player. I looked at the "futures" of interesting move points and discouraged self-atari moves unless the future belonged to the player executing the move. (A "future" is the expected percentage of time a given player ended up with a given point at the end of the random games.) So some sort of pre-processed quick all-moves-as-first random play-out can give you a sense of which self-atari points are interesting. But it is not dynamic unfortunately and thus not scalable unless done periodically during the tree search.
