BTN is a reg-fish. Pretty loose and kind of passive. Plays with more aggression HU and IP.

He was opening 42% of BTN's and I didn't want to 3Bet, but this hand is good enough to see a flop with, with an ultra tight BB behind me.

He CBets and I go ahead with a X/R. He is going to be betting a ton on this dry of a flop. I have 77 which makes his wrap combos WAY less likely and he is going to 3Bet the flop with any of his premium value hands (any set or two pair). I also thought this gave me some deception. I have one of the only two flop draws and it's pretty obvious when I hit. When he calls I think he can have a pair+overs, 43, maybe a pair+BDFD. In general, a hand that is too good to fold, but not enough to 3Bet OTF.

Since I don't have a lot of SD value in reality, I go ahead and pot it looking to maximize my fold equity. I think it's very credible because the Qs brings in a ton of draws. IMO, he's also most likely to think I have a set by potting it here because that's what he would do. Against fish, I think acting in a similar manner to how they would act with certain hands in spots can really help us rep a specific hand category.

When he calls, I think he may have picked up a flush draw, but not two pair. I think he'd probably jam his Q8/Q5, but when he calls I still think he has some kind of draw, be it one of the flop straight draws or backdoor spades.

When the board pairs it is a mandatory shove and seeing his actual hand I'm not totally surprised he called, but am a little. It tells me he either isn't reading hands, thinks my X/R's OTF are more with (semi) bluffs than for value, or he just can't lay down a "strong" hand like the nut flush when he should. Also, he must not have thought his AA were good OTT otherwise he would've shoved turn, so if he was reading my hand I guess he saw it as two pair.
