In Response To: -3-4 cube action - XG 4-ply RO (poseidon)

Here is Gnu's rollout (I had to stop it at 1255 games) which generally agrees with XG.

What is interesting it the difference between XG's and GNU's estimation of Blue's gammons after the double:

XG: G: 35,88 BG: 14,62
GNU: G: 39,1 BG: 20,2

The score (after 0 games) is: gnubg 3, Player 1 4 (match to 7 points)

Move number 2: Player 1 on roll, cube decision?

gnubg	197
Player 1	140
Position ID: 4Dl4AFyY55gDEA Match ID: cAngADAAIAAE

• Player 1 doubles

Alert: wrong double ( -0.178)! [very bad]

Cube decision
Rollout cubeless equity		+0.855	(Money: +0.753)
Cubeful equities:
1.	No double	+0.850
2.	Double, pass	+1.000	+0.150
3.	Double, take	+0.672	-0.178
Proper cube action:		No double, take (54.3%)
