I think his value range is a lot of 7x, but not boats or quads
so 78, 75s, 76, 7Ts, K7s type of crap because if he had a boat or quads he'd either slowplay or c/r the turn (or donk small)
but the lone seven is the kind of hand that is like shit, I don't want to get sucked out by a draw

his semi-bluff range is clubs without the ace most of the time because it would make more sense to raise the flop with a straight draw
if he had the ace, he'd be more inclined to bet or c/c since he has showdown value and has very little to fear from other draws

so now we have to see how much air he has in his range

having done this analysis, we're either like crushing him or we are owned hardcore so we basically have a bluff catcher
thread title might as well be 25nl bluff catcher ??

the hands that he could turn into a bluff are pretty much pps that he called the flop with and then randomly changed his mind
I mean why would he call the flop with KQ and then shove the turn anyway, nothing really changed to make an ace fold this
I just don't think he can expect us to fold an ace which is why I fold

I realize I give my opponent a lot of credit, but he's telling me something very congruent with how a weak-tight plays 7x
