I have played several games with the 5 dan CrazyStone (24 cores) and felt that it is pretty close to the 5 dan Zen (26 cores) in playing strength. In fact, CrazyStone’s playing style is much more balanced and human-like than Zen. Specifically, CrazyStone is better than Zen at winning without killing or fighting. It has a very good sense of territory and features very good pattern shapes, though it is still weaker than Zen in handling semeais.
Blitz games such as 15s/move favor MCTS programs. I expect both Zen and CrazyStone will drop to 4d in longer games. The reason is that MCTS programs are still not able to (in my opinion) read deepily like human players in situations such as big semeai or life-and-death. Also, when against strong Go players in fast games MCTS programs rely heavily on accurate territory counting. In longer games, this advantage will decrease most if not at all.

In the last few days it was 15 seconds per move, with 9 byoyomi phases. I don't think that specifies the time control does it? So if a player exceeds 15 seconds he starts to use one of his byoyomi periods? How long for the byoyomi phases? I don't think 15 seconds per move average is bad for humans at all, but if you have to make each move in 15 seconds it's horrible and I can see that this is going to make the computer really look good. For making strength claims there should be some sort of standard. You could take almost any program and get 5 dan or more by setting the time to 1 second per move.
