I didnt notice the time limit was 30 minutes per side. The web page still says 20 minutes. Id also prefer 20 minutes per side, to get a few more games in.

Is current CGOS 19x19 30 minutes per side? not 20 minutes? I like short time setting.

I have two version of Many Faces (636, from last March, and 737, the latest, both on 4 cores). Fuego is there twice, running on 56 cores and 4 cores. Pamogo, is it a version of mogo? Enos, a new very strong program. Does anyone know who it is? Valkyria is there. Zen and Aya and Suzie and Crazystone are missing.

About ten strong programs have not played for some while.

That's where this estimate comes from.

Playing losing positions is tricky. The perfect move for w minimax wise in handicap 4 is resign. So maybe accepting that initially white loses by b_0 points and playing always a move that keeps this minimax value expecting blacks suboptimal choices to make b_i negative for some i is probably not the best strategy. It is accepting: Ok i am behind by (say) 45 points, lets build a solid 45 point loss. We can imagine how much a human pro can read from what Catailin Taranu explains from his own games in his eurogotv.com videos. Humans narrow the search very much an may foresee say 20 moves. (Anyone reads 20 moves in a ladder I mean 20 moves in a fight.) A perfect player could read 300-400 ply full width. Obviously, it could also compute what humans will not see or may see. Rather than perfect play, an aggressive overhuman 300 ply deep full board tesuji could probably include killing the 4 handicap stones for free. If perfect play means overhuman tesuji I guess 4 handicap stones is too few. Paradoxically, perfect evaluation can be a drawback and minimax wise perfect play could be non-aggressive. Of course, we can bet as high as we want because we will never know.
