This one felt a bit like an Othello-quiz problem to me. I "cheated" a bit because this didn't actually come up at 3a4a, and I tinkered with the score to make the #2 play a whopper, but 5/4*(3) is the bot play at most scores. Despite Magriel's criteria, there isn't enough positional gain to justify leaving a blot.
