Correction: "most non-random tactics" wouldn't make it better, as someone else pointed out. Finding ones that do is a tough question, beyond just runtime; keep in mind that the MC player uses that strategy against itself over entire random games, which can lead to really un-humanlike games. Completely random games at least ensure that you're hitting all possibilities (and when that good move is found, that path is explored more).
