Sorry, should have edited to choose my words better. I almost never see a weird lead like this and it didn't make sense to me which is why I called.

I should have asked:
How often do aggressive 2+2ers have fish take the lead on the turn in spots like this? What hand could he have that makes sense to take this line?

Agree with quesuerte that you can't think about why it "makes sense". When you're opening a lot, fish are flatting you with AJ/88 and folding if they miss the flop, and 3 betting you with QQ+ which you obviously fold to. Don't ask why it "makes sense", it doesn't.

When I see loose-passive fish take this line it's almost always because they hit the turn. I'd say most likely T8 or 85, but sometimes J9 or 88, and maybe even Q8?

The fact that he's won zero pots implies that he's folding most of his range, right?

Not IMO, I think he wants to win since his GF is now winning after sucking out vs me with 55. Also, V was not as passive as is being replied in this thread. He triple barrel bluffed with Q high!

There really is a dynamic at the table I can feel regarding his lady sitting next to me and now winning and chatting with me since she feels good (and saying how sorry she is to beat my Kings), and him across the table watching this and not winning any significant pots.

I also am not raising as often as is being implied by replies, I have been mostly card dead and have only opened three (maybe four) pots recently, two that were shown down - AA and KK.

So I guess I may have butchered the way I posted hand action and reads not being together. I don't want to sound results oriented either so I'll give all the read info I got on river when he shoved now...

At first my instinct was to insta-fold, but I NEVER do that anymore. I always try to think and study my opponent. When he first shoved he looked normal and like he had before, then I ask how much and begin to cut out my chips.

At this point he starts watching me VERY closely, and looks pretty nervous overall when I cut out the call and push it away from the rest of my stack. I then start looking at him pretty hard, so he stares right back with dialated pupils (means his brain is trying to take in a lot of information, which here I take to mean he is trying to figure out what I'm doing and doesn't have the nuts).

Then I get deja vu from him, he starts TRYING to look comfortable. He sits back in his chair, looks away, looks back, takes a sip of his beer... etc. I had done this same thing a long time ago when I was bluffing and trying to make the guy fold with my actions (I almost never do anything anymore unless I want a call!). This bad acting went on for a while and was 90% of why I chose to call.

He sheepishly (doesn't want to show at first so I know I'm good) turns over 56o for bottom pair on the flop unimproved. I talked to him later as I was leaving and he said he thought I had a big hand like an overpair and that I would fold, and also that he did it because of the 5's his GF had and so 5's were supposed to win at the table tonight

Basically I posted this hand to ask how much merit do we put in our reads in spots like this one?
I recently replied in a thread that asked which do you prefer, longer or shorter sessions when you play? I replied longer because it gives me all the infomation possible, especially regarding how players are playing and the table dynamic.

The line made very little sense to me if he had a monster, and I chose to rely on my redraw/gut on the turn, then I relied like 90% on my body language read on the shoved river.

I feel like going with your gut and reads is risky, but in some spots we dont do it enough, anyone else care to weigh in on this?
If not, sorry I didn't include reads as much to start, but they are long and I wanted to see if this was ever a call based mostly on the cards/action.

I'm not going to agree that turn is a clear fold here. This is a very bluffy line. I suppose he could have spiked two pair here, but it seems unlikely, especially since we have a blocker to top pair. Feels like a weak hand.

Barring a dynamic, I don't think calling down turn and checking back or calling a shove read-dependent on the river is a bad play at all. I feel like he would go for the check-raise on the turn with the goods. Also, he's three barrel bluffed at a pot, which to me, says he's capable of some ****. It's not like we're playing against a 70-year-old nit here.

Haha, I'd forgotten about this hand, but I'm glad at least one other person thought the line didn't make enough sense and would have also called. After my reads on the river it made that call easier as well.

I'm still trying to figure out how much to risk in spots where out gut/reads tell us to make a move or call a big bet...
