2-away, 2-away cube strategy
Hi, I am not really a player but very interested in the theoretical analysis of optimal cube play. I have come across claims that optimal play at the 2-away, 2-away position is to double at the first advantage, or at the first possibility of a market loser. I have read many arguments for these claims. But I still do not understand, so I am hoping someone here can assist.
As far as I understand, the take point defines the threshold for optimal cube play. E.g. in money play the take point is 75% and for the 2-away, 2-away position in question it’s about 70%. I can understand there may be some adjustments for market losers but don’t see how we from 70% to just anything over 50%.
I am looking for a simple mathematical/game theoretic explanation. As I am not a player, I would also appreciate any distinction between theoretical results and practicality - for example maybe the optimal point really is 70% but for practical reasons people adopt another strategy. Thanks!
