I didn't mean borderline take, but say something like a 0.9 take. Way off in any case!
Apparently I overrated our own prime/blockade somewhat, and more importantly, seriously underestimated monk's chances to block/attack our backchecker which eventually might cause trouble with our prime upfront, forcing us to crack it and perhaps in a bad way even. After such a scenario, escaping two backcheckers will be that much easier for monk to do.
The loss of our own midpoint, combined with monk's 3 checkers on his midpoint and some other outfield checkers means monk will have outfield control for several turns, making it hard to escape the backman safely, much harder than I'd thought earlier.
So, it's a gigantic take. Even so it's less than a 0.1 error to cube here, probably because an escape and a miss by monk is a big marketloser, so volatility is high.
Practically speaking, this might not be such a bad cube against many players, since I can see a significant percentage of drops here, and then you gain enormously.
