RED is offering the cube, WHITE to take in the situation described .. i clarified that in the question

but that very thought occurred to me during the game, it almost looked like a better cube for me (WHITE) than for rollingfool (RED) .. had it been my turn and the match score different, it looked as if a cube by me was a valid play

yes, but that is only part of the question .. also, let's not give away too much of the answer with replies .. remember, voters can see this before they vote

btw, Tomawaky, thanks for the idea of how to include an image of the board in the question  :shakehands: .. see Cube 103 (http://www.fibsboard.com/improving-your-backgammon-skills/cube-103-t1769.0.html) for an example .. i haven't been able to upload an image of the board yet, but i used your banner
(http://fibsleagammon.free.fr/minifibs.gif)
from another post to test the idea .. it's looking as if it may work .. i'll change the link to the board image as soon as i can find a place to put it

Spoiler
You should double if there is even slight possibility to lose markets when your opponent is 2-away. This is a good rule of thumb. Like in this position very good rolls (61, 31, 11, 44, 33, 66, 55, 64) could lead to double, pass. But... i made a bad double in this score also. So you could add to rule: that you shouldn't double if you're not favorite to win (exceptions to that propably too when very likely to gammon). And also which I often forgot is that there are no market losers if opponent has solid high anchor (unless behind huge prime or big race lead).

Well this problem has been up long enough I think. This position, which is an excellent double by rollingfool and a clear take, belongs to a class of positions under the heading of "One way gammon threat, dead cube". After doubling, only Red benefits from a gammon and the cube is of no value to White. 3-away, 2-away and 4-away, 2-away are the scores at which you need to be alert to these. This cube would be even more potent at 4-away, 2-away, so much so that White should pass! That is because at 3-away, 2-away, Red has some wastage if he wins a doubled gammon; he can only use three of the four points for that. However, there is an upside too, which is that Red doesn't need to go crazy to win a gammon here, because a doubled plain game gets him to Crawford, where his winning chances are about 70%.
Instructive position. Learn and copy.
