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 game sequence:

bC4 wD3 bC3 wD4 bD5 wE5 bD2 wE2 ...

The beginning is very natural, and although I did not check carefully all what Don reported but I think there is agreement that this is a strong seqence for both colors.

... bE3 wE4 bE1 wF3!!!...

Normally wF2 is played in the corner. But with wF3 white has the option to play aggresively with wF1 which usually is a bad idea because the ko fight risk to much. But on a small board things are not normal...

... bC1 wC5 bB5 wD6 bB6 wF1!...

white starts a ko. If white first plays wC6 bF1 wins the game right away.

...bF2 wC6 bB4!!!!!

if I understand this move it is a truly cool move. If black plays the larg ko at E3 as most people would instinctively do including myself white cuts at B4 and get a lot of kothreats and wins the game. With bB4 white has no ko threats.

...wF1 bE6 wF6 bF2 wE3 bD1 wF1 bF5 wF4 bF2 wPass bF1 B+3.5

So komi should be larger unless there are a mistakes by white in this sequence.

Valkyria should have the credit for all strong moves here but they are not always found, so this analysis is also shaky. At short time controls I do not think any existing MC programs will get these things right.

Even if it is wrong I found some of the moves really fascinating. The search behavior of Valkyria jumps up and down between 25-75% all the time as these moves are found. If it had been more stable maybe I could just let it run for a long time and find out stuff more or less for sure. But I hope this sequence adds some understanding at least.


Quoting Don Dailey <[EMAIL PROTECTED]>:

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 is the
correct komi for 6x6 go?
