Hero?

BB - Fish
BTN - Reg playing 22/18/9 over ~300 hands

Easily my most butchered hand of the day.

The fish being in the pot made me want to trap him while completely ignoring BTN's presence.

Things I could have done that I should have
-Raise Flop
-Bet Turn for ~70% pot
-Bet River bigger

But since I didn't...what is your play here?

I would call. Guy is repping exactly KXss right? Maybe he turns KxQs into a bluff or something like JTs, but his value range should be very narrow. Maybe muck more when you don't have Ts to block some of those flop call/turn xx/river raise XXss combos. I'm not thrilled, but not folding either.

T blocks a ton of his value range maybe even a majority so not folding. Not a terrible spot without a spade but it is a multiway river raise.
