It was interesting to play against, but it got stuck into a threefold repetition and the match ended in a draw, maybe do something to detect move cycles.
More so than not detecting threefold repetition, it is actually not good at endgames in general, very frequently struggling to find checkmates more than just a few plies deep. I’ve heard anecdotes from friends that played it, where they were able to converge from a losing position during the late middlegame or the endgame.
