implemented (when not smart) as trying to match the human's score to a per-robot value between 1 and 100 that gives the percentage of best moves to store before picking randomly from among them. So a 1 means save only the best move and always pick it; 100 means save all the best moves (how many are saved is compile-time configurable) and pick one of them. Because it's settable per-robot a smarter robot can be played against a dumber one (though I may choose not to make it settable per-robot on shipping versions.)
