The position below arose in one of my games and according these rollouts, there is some chance that it is a "fourscore position," i.e., a position for which the equilibrium play is different for money/DMP/GG/GS. There are at least two caveats.
1. Even if we take the rollouts at face value, the margins are very small in 3 out of 4 cases, so a longer/stronger rollout could yield a different verdict.
2. The blotty board is the sort of thing that sometimes induces XG to play like a donkey.
Still, even if this particular position doesn't pan out, perhaps some tinkering will fix that.
