The difference in plays is a bit staggering considering how simple the position seems. To easily understand this I put both positions into a separate instatiation of GNU, made one play in each, gave White (me) the same mediocre roll and then looked at how all of Blue's (Neil's) upcoming rolls played on 2 ply.

The score (after 5 games) is: Stick 6, neilkaz 5 (match to 9 points)
