On comparable hardware, Yace by default needs 23 minutes. One other interesting observation. When using conventional piece values (1/3/3/5/9) and not any kind of "bad trade penalties", this time is reduced to 3 minutes, in 4 minutes draw score, and in 20 minutes around +0.8. This happens often in test positions, but in my tests, it makes the engine weaker. It will however make the games more spectacular, because it will see compensation to some piece sacs easier, and this will yield in a more attacking style, that sometimes can give a short winning game.
