In Response To: Somewhat disturbing GNU 4-ply error (Timothy Chow)

A Snowie 3-ply eval (GNU 2-ply equivalent) shows this as a 0.1 error to NOT take. A short rollout still shows about a 0.06 error to pass.

My initial reaction looking at this position was to take. Noting similarity to another benchmark postion - take the usual opening 52S-55PP-dance blitz cube by making the opponent's 5 point as if with an extra 31 play - that is ND/T. THe 4 point is weaker than the 5, but the 2 is weaker than the 3 (but perhaps not so much in a blitz). However, I learned a hard lesson in the semis in Monte Carlo how a single extra checker in the zone can make a monster difference - a bare ND/T turning into a D/P. I am therefore not at all surprise to see that this could be a small pass.
