I am playing games with Leela at 5 minutes per side on a loaded core 2 duo computer. From the evidence I have now, which I admit is not enough to base a solid conclusion on, it looks like 2.0 is the correct komi. When I set komi to 1.5, black has won 10 out of 10 games. When I set komi to 2.5, black onl wins 16.667% or 2 out of 12 games. When I did the 7x7 study over a year ago (or maybe 2) I noticed that at reasonably strong levels it tended to be very one sided in one direction or other based on how you set komi. My plan is to run a LOT of games at 2.5 komi and then analyze the results based on the move sequences looking to see if some common early black blunder is preventing wins for black at 2.5 komi. When I do this I will try to reorient the move sequence to some canonical representation so that we are not looking at too many equivalent games with different orientations. Superficially, I noticed this: 1 W C4 D3 C3 D4 D2 E2 1 B C4 D3 C3 D4 D5 C2 Which means when black played D5 on move 5 he won, but when he played D2 he lost. 1 B C4 D3 C3 D4 D2 E2 D5 E5 E3 1 W C4 D3 C3 D4 D2 E2 D5 E5 E4 Same above - Black played 2 different moves and got two different results. The other games vary before this but could be transpositions of these positions - I don't have the time right now to compute all the transpositions to check this out. I didn't actually look at those moves so I don't know if they are game changing or not. Are there any strong players willing to comment on these 2 diversions? The other possibility is that white is supposed to WIN all those games and is making the occasional error. The results indicate that is a more likely possibility. Here is the complete list of games up to the 9th move. The first column is the number of times this exact result/sequence was played. 1 W D4 C3 C4 D3 B3 B2 D2 C2 E4 1 W D4 C3 D3 C4 C5 B5 B3 C2 D6 1 B C4 D3 C3 D4 D2 E2 D5 E5 E3 1 W C4 D3 C3 D4 D2 E2 D5 E5 E4 1 B C4 D3 C3 D4 D5 C2 E5 B2 D2 1 W C4 D3 C3 D4 D5 E5 D2 E2 E4 1 W C4 D3 D4 C3 B3 B2 E3 E2 D2 1 W C3 D4 C4 D3 D2 C5 E2 B5 E4 1 W C3 D4 C4 D3 D2 E2 D5 E5 E4 2 W C3 D4 C4 D3 D5 E5 D2 E2 E4 1 W C3 D4 D3 C4 B3 E3 E2 E4 B5 1 W C3 D4 D3 C4 B4 B5 D5 B3 B2 2 W C3 D4 D3 C4 B4 B5 E4 E5 D5 - Don 1 W C4 D3 C3 D4 D2 E2 1 B C4 D3 C3 D4 D5 C2 But for now, perhaps you stronger go players can look at the following 6 moves sequences that represent the games. The first column is how many times this exact result/sequence occurred. For instance you see that white won 3 times when the game started "C3 D4 D3 C4 B4 B5" Does anyone see any obviously bad moves for black? 1 W D4 C3 C4 D3 B3 B2 1 W D4 C3 D3 C4 C5 B5 1 B C4 D3 C3 D4 D2 E2 1 W C4 D3 C3 D4 D2 E2 1 B C4 D3 C3 D4 D5 C2 1 W C4 D3 C3 D4 D5 E5 1 W C4 D3 D4 C3 B3 B2 1 W C3 D4 C4 D3 D2 C5 1 W C3 D4 C4 D3 D2 E2 1 W C3 D4 C4 D3 D5 E5 1 W C3 D4 D3 C4 B3 E3 3 W C3 D4 D3 C4 B4 B5 What I see that is slightly interesting (just from this data, not looking at the actual position) is that C4 D3 C3 D4 D2 > > Erik > _______________________________________________ > computer-go mailing list > email@example.com > http://www.computer-go.org/mailman/listinfo/computer-go/
