This felt kinda bad but I wasn't really sure how else to play it. CO is a tight TAG, 16/8/2.8 over 900 hands with a fold to cbet of 86%. Button is a huge station so it's real unlikely he was floating light on the flop. He could easily have called with 55 though and possibly a flopped straight in order to keep button in the hand. Anyone got a better line here?

bet 34$ on turn, and then follow up on river.

As played call turn/river.

He could have 55 but he could also have 66/77/88/99/TT.

It's called a "set" when two of the cards are in your hand.

Anyhoo, this is a really crappy spot. I hate folding sets... I guess he *could* play an overpair like this after you show weakness on the turn, but normally he'd just show it down on the river in that case, so I guess I sigh and fold.
