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 wF

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 statisti

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 2.0
