Darren, I was able to parse the file without any problem. I considered all board configurations in file as GOOD positions, so that any move that can reach any board position in the file is considered a good move or a hit. I was testing against GNU Go,and wasn't get much hit after 2 moves, which is about the same as my small open book build out of 100 professional games, which seems strange to me. Anyway, I could have made a mistake here or there in rush of time because I was preparing for the competition. I will test it again, now I have more time.
