G3 and E3 get less than 20 playouts (so, not really seriously considered), with sub 20% winrate each

Other options are to tenuki, but with kinda low playouts (lower than B3).

Edit : added the "best" continuation that LZ plan for each of these moves

It's even the only move it consider (over 65k playout for it, while the others are all under 500)

Hi Tryss,

Thank you.

Noob question: is there a significance between the 40k (E4) v. 16k (F3) playouts ? Their winrates are very close ( 21.3% & 21.6% ),
but the playouts are quite different ?

Is it Lizzie ? Very pretty interface. :tmbup:

Just curious: what's LZ's winrate for :w1: , given 2-stones ?
Does :white:'s winrate start from ~0% and climb up to ~20% by :b18: ?
Or is it the opposite ? :white:'s winrate starts out higher than 20% at :w1: ( but under 50%, obviously ), and drops to ~20% by :b18: ?

Before :w1:, LZ gives white around 21% winrate, so there is no real winrate change by :b18:. Note that this evaluation is with 7.5 komi for white .


For the playouts, I'm pretty sure the difference is noise (due to the randomness of the tree exploration). I just did another run, and the results were :

F3 : 21.4% winrate with 42k playouts

E4 : 21.0% winrate with 33k playouts

B3 : 20.5% winrate with 8k playouts

So while last time LZ would have played E4, this time it would have played F3.

(I spend a little more playouts here, but the result would have been the same if I stopped a little earlier : F3 took the lead early this time)


And yes, this is lizzie

Huh, interesting analysis. I'm surprised W is down to only ~20% winrate after less that 20 moves!
