This function gives two options for organizing candidate moves: 1. No move better than interesting. 2. Interesting better than no evaluation. I don't understand what these two statements mean. So is an interesting move bad or good?. Is it the best move you can make, the worst move, or somewhere inbetween? These options seem to contradict each other. The first sounds like interesting is a strong move "no move better than interesting". Then the second makes it seem like it's not the best move but it's better than nothing. "interesting better than no evaluation"
