What are the things that get you folks curious?

Today I was playing some 5-10 and raised Q9ss from the CO.

Button, a fullstacked random tagg flatted.

Flop was , I bet my usual 65 into 85 and villain quickly called.

Turn was

ooh! Scary board! At this point I almost always 2 barrel and then check-fold the riv or I just check-fold.

However

I decided to check and call a bet that seemed suspicious. So many of normal taggy villain hands have flopped gutters, A hi + backdoor FD's, small pairs that call in order to bluff a later street on scare cards, etc.

Villain bet a whopping 200 into 210.

O RLY? At this point I was pretty sure I was being pushed off the hand by a float. Of course, there are a million gross rivers that can kill my hand. I decided to just close my eyes if the river bricked off and click the "check/call any" button.

When the hit the river, I clicked it, closed my eyes, and looked up 5 seconds later to see a big pot shipped my way vs his overbet riv shove w

So obviously, there's no veil over this brag. But it got me wondering : what are the things that, at any point in a hand, make you guys go "HMMMMMMMM time for me to make myself a nice big peanut butter and cally sandwich"?

I used to make these thin calls too much, but now I kind of wait until the urge is just too strong to resist. I know this is a very broad subject, but either specific stories or recurring patterns would be fun for the thread.
