Hello Magnus, there was indeed a notation error in your original posting. There you give 13.C1 (see last line below) and not 13.C2 as in the sgf. Ingo. I have been trying to see what Valkyria does. But it is a little unstable when it reads deep at 6x6. It should not be a problem for

I would be very interested in various opinions on this. Is the correct komi for 6x6 (under CGOS type rules) 2.0? Especially would I like to see some strong players review my (actually Leela's) analysis and weight in on this. Do you think we can say with relatively high confidence that

I have been trying to see what Valkyria does. But it is a little unstable when it reads deep at 6x6. It should not be a problem for Valkyria but I have not had any time to search for the bug. Anyway the 2.5 komi black should lose if Don is right. So I have the following very cute complete

Magnus, It seems I didn't go deep enough into the game. I assumed that after quite a few moves we could reach some tentative conclusion that was likely to be correct, but it looks like there is a good chance it is not correct! What I should have done was to take the time to mini-max the

I stubbornly always use x.5 komi because I do not like Jigo. in this case it was 2.5. I do that simply because Valkyria is coded like that, it cannot play with integer komi. Quoting Christoph Birk [EMAIL PROTECTED]: On Tue, 30 Sep 2008, Magnus Persson wrote: ...wF1 bE6 wF6 bF2 wE3 bD1 wF1
