I'm a fishy reg so I'm more posting thoughts than advice.

I'd look at it this way. What do you think beats you here & why would he bet like that?

From my view, the nuts would be T9, 2nd any 5 holding and 3rd QQ.

I'd take away QQ since he's got position & would surely want to build the pot rather than check the turn with top set unless he's massively tricky (just add a note if he does this to induce a bluff).

T9. You don't have many hands on him, but do you feel he's going to play that from UTG? It's very possible but just as impossible. With so few hands you would struggle to tell. He does have 16 chances to play it & there was no reason for him to bail out as you've put no pressure on him.

Any 5 holding. There's 4 & does the play fit? More likely in my opinion. He's likely to open 55 that way, do a cbet then check turn for control. An aggressive player realising he has 8 cards for the oe straight draw + 2 to make a set might well bet on the turn. You've not enough data to tell but. Other very good possibilities for 5 are A5s, 56 (but again, UTG?)

So that's what beats you.

Here's what you beat.

AQ, KQ, QJ, 66,44,77, any 2 pair like 67, 64, 78

For me, I think you're so far ahead of so many hands that I would call.

If I put in 26% range in to poker stove (includes 55,T9) against your 88 and come up with you being 99% to win.

As much as I respect Bike's abilities I can't see how this isn't a call. You are so far ahead of so many hands that would do this and get nailed by a any 5 or T9 combination. It's possible but I think you beat so many other hands (like 2 pair) that would do this.

I guess that's why I lose long term but
