[Scotch78]

I would need a pretty solid read that the button's stealing range is in the 40% range to defend here. Besides the obvious factors, you need to consider game structure. First, Party's rake at 3/6 6max is high, and that hurts the profitability of defending. Second, but not as significant, there is less dead money because of the 1-3 blind structure. Together, these factors probably skim .5-.75 SB off your EV, as compared to defending at, say 10/20.

If you consider that this hand is marginally profitable at best, I think it's an easy fold in this game unless the button is a clear LAG.
