The largest nakade shape is the rabbity six. My wild guess would be to
outlaw self-atari for groups of 7+ stones.

Outlawing self-atari of 18+ stones
Terry McI announced:
On Friday, August 8th, at 3 PM Eastern Daylight Time,
Myungwan Kim 8P will play against Many Faces of Go.
One question, do you mean
Friday, August 7th, 2009
or
Saturday, August 8th, 2009
or another year ;-)
Thanks for informing us.
Cheers, Ingo.

Friday the 7th.
You may check ManyFaces1 on KGS -- this is the program which will be playing -
it is using 8 cores now - may be using more cores by Friday.

It's easy to construct self-atari of unlimited size that both
can occur and should be played, if the capturing move that follows
the self-atari is then recaptured in a snapback.

You should set the limit to whatever yields the highest ELO in YOUR program.

We got 32 cores working yesterday so it will use at least 32 cores. At last
year’s world championship we used 32 cores because more cores was weaker (even
though we had 1024 cores available). Today’s version should scale better, so
if we have time today we’ll play 32 vs 64 and see if 64 cores
This is probably the best route. Either this, or get rid of the rule.
This rule cannot be shown to be correct in general, it may work for most
life and death problems, but can be wrong in semeai. You may get a nice
ELO increase, but you are still actively building a wrong rule into the
Actually, it's even worse than this: following LibEGO, my playouts
allow (multi-stone) suicide!
I may fix this before this weekend's KGS tournament.

I procrastinate, but I'll compete. I may enter more than one bot, but
that depends on how much prep time I have.
While RAVE is a very strong heuristic, in Fuego it occasionally
suppresses the only good move. Do others have similar experiences?
Here are two cases that I just added to our regression tests. Does
anyone have more?

I fixed allowing multiple suicide in playouts, but it didn't make the
many wasted playouts go away on Sheppard's position.
On further investivation, the problem has to do with the interaction
between superko and the transposition table.
Currently, Orego checks only simple ko most of the
I check for superko during the UCT tree part of the search, but just simple
ko during playouts.
