GnuBG 2-ply rollout:

Spoiler

For some odd reason, GnuBG prefers 13/9 7/6 on evaluation! Rollout corrects it though:


    1. Rollout          7/6 5/1                      Eq.:  -0,0006
        46,83   9,45   0,54 -  53,17  19,06   0,57 CL  -0,0006
      [  0,15   0,19   0,18 -   0,15   0,45   0,16 CL   0,0033]
        Full cubeless rollout (trunc. at one-sided bearoff) with var.redn.
        1296 games, Mersenne Twister dice gen. with seed 859211562 and quasi-random dice
        Play:  2-ply cubeless prune
        keep the first 0 0-ply moves and up to 8 more moves within equity 0,1
        Skip pruning for 1-ply moves.
        Cube: 0-ply cubeful prune
    2. Rollout          13/9 7/6                     Eq.:  -0,0375 ( -0,0369)
        45,12   9,06   0,83 -  54,88  19,74   0,25 CL  -0,0375
