Obviously we're pretty near the top of our range, but I felt at the time there was a pretty legitimate case for folding. Opener is fairly standard, opens a little too much utg (19%) and not quite enough everywhere else, but there's nothing else special about him. Has not shown down a bluff in any of the hands we have on him. MP is a bad nitreg, folds too much and isn't really very positionally aware. Basically 3bs all his good hands, so we can safely rule out AK, AA, KK, QQ from his preflop calling range. Possibly JJ too, although that's right on the borderline. Can have a bunch of higher card spade combos too.
I tanked for quite a long time otr, and was really not sure what to do. Seemed really marginal either way. What do we reckon?
