At 5a 7a the leader has an elevated takepoint, but the trailer has a
fairly "normal" takepoint of about 19%. Does O have that? Her board is
weak but still something, and she has an advanced anchor plus a
substantial lead in the race. So, I'll say take. The crunched board
and the straggler on the ace plus the blot make me think there's enough
market losers to ship it. Yeah, X doesn't want to eat an eight cube,
but that's a calculated risk.

D/T.

Like ah...clem, I thought that O's position was wrecked enough to
justify a redouble even at this score. However, O has the golden
anchor and a large lead in the pip count, which XG thinks gives her
position enough resilience that it doesn't think X should redouble
just yet. As an illustration, I have rolled out a possible cube
decision that X might face now if he doesn't redouble now: suppose
X rolls 52 (played 20/18* 17/12) and O enters with 65 (played bar/14).
XG thinks that O would still be able to take. So there aren't all
that many market losers, according to XG.

As a variant, I have downgraded O's anchor to the 4pt, and then XG
thinks it's a borderline redouble.
