The Forum decided to hit loose 8/4* on its last turn, roadkillbooks rolls a 2-6 from the bar to enter one checker. Cube decision for the Forum (blue):

The fascist's feelings of insecurity run so deep that he desperately needs a classification of some things as successful or superior and other things as failed or inferior. This also underlies the fascist's embracement of concepts like mental illness and IQ tests.  - R.J.V.

A 37 pip lead. 
We threaten to make a fourth point in our homeboard.  Any 4,  any 2 and especially 6-2 is devastating.
We have a three point board vs a two point board.

That's three for three in the position-race-threats triumvirate.  Market losers abound.  So definitely good enough.

The question is, is it too good?  Maybe, but lots can still happen here, and with rkb holding the golden anchor gammon chances are slim.

DOUBLE.

Looks like a pass at this match score, but rkb may surprise me here.

This would be far from double in even score. High anchor is so strong asset and we have still major part of our army far from home. The game (and holding) will continue long time and rkb will have lot chances to hit and even up. However in this score I would double. There are some gammons lurking around and we don't want lose them with market loser sequences. If I were on take/pass side I would have to stop for awhile to think (because score) but looks like a take. Gammons can't be pass high because solid anchor.

The Forum doubled, will roadkillbooks take? See the diagram at the start of the thread.

TAKE. Seems like a simple trivial take even at this match score. I like my anchor and right now I have only one piece in the air.  If I had danced it might be different.

GnuBG 2-ply rollout of cube decision:

Spoiler

It's a double, but not by all that much. We win only about 59% of the games here.  It's the very high gammon rate, medium volatility and the matchscore that turn this into a double.
