    Increadable!!! I love the way the auther speaks so passionately about the engine on his website. Quite human like play - loves opining lines and avoids closed positions. Interestingly I played a queen odds match against Komdo 13 - forced it into a closed position, and slowly squeezed the dragon to death. I then played Chiron, despite Chiron starting a queen down I could not hold Chiron into a closed possition, it worked out deep tatical tricks and crushed me. Out performing Komodo in this match
