You have basically 2 cases when losing. One case is that the program
really is busted and is in a dead lost position.The other case is
that the program THINKS it's lost but really is winning (or at least has
excellent chances.) In the first case, we are simply playing for a

I am new here, but have read the list for a few monthes.
I am a mathematician, finishing my PhD on quantum statistics (that is

Naively put: if all results say the game is lost, switch the
evaluation to best possible score and continue playing for a while.
If any winning paths appear, switch

That would mean that in a scalability study, where colors are

Improved view and more games. After 1336 games black still wins. This

equivalent) is the most popular move for cgos.
I think I should nega-max the percentages instead of showing it just

walks the tree, only showing canonical versions of each move.

Unless you used some MC bot, then W would still win by 0.5 :)

It's a little less because a few more games were played when I compile

All the games begin with E5 by the way.

Hi, here comes the simple explanation, but some more data as indicated
below might of course empirically overturn this.
There are 81 points to split.
If black has 44 and white 37 points then white komi 7 there is jigo.
But when black get 1 point more white also get one point less. The

Magnus,
I'm getting an odd result with Mogo. I am running games at a fairly
decent level with 6.5 and 8.5 komi to see what will happen.
At 6.5 komi we get this:
* B = 289 = 0.58859
W = 202 = 0.41141*
At 8.5 komi we get this:
* B = 383 = 0.52610
W = 345 = 0.47390
46 E5 C5
By the way, mogoRelease with moderate computation times often plays
E5-C5-C6, and this third move C6 is very weak (at least I've
