It's funny you mention that I could have KQ, because I thought it was pretty obvious I had a really strong hand and wasn't drawing, otherwise I'd raise the turn. If Villain was the type of player to have QQ and Villain bet the turn to see where he's at and protect against a 4th diamond, then Villain seems like the type of player who will 3bet me on the flop to protect his middle set, and would also re-raise with it pre.

K3 is possible but i don't think he is such a bad player that he called my 3bet pre with K3, even if its K3d (which would be ideal hand to have here)

My thought during the hand was that if we look at the turn, his bet didn't really make sense, 650 into a 1300 pot, giving me odds to call with a FD. If we consider the 650 as sort of a blocker bet that means he needs to have a pretty good hand OTF. Or villain actually made the flush and was betting for value, but then the river didn't really make sense unless he is a super donkey, because I can only call river with a FH or at worst nut flush.

If I call the river int his situation, I'm basically saying I'd also call with a nut or 2nd nut flush right?

So was the Q on the flop a diamond instead of the K? You said K was both on the flop and in his hand?

+1 to everything in this post

And tbh you tanking for 5mins on the river is a slowroll

This makes it sound like you put Villain on a turned flush. And you couldn't find a fold there, even when you were behind. So why would you try to justify a fold on the river when your hand gets stronger?

the Q was a diamond on the flop. I think I made a mistake in the post.. After the hand he said he thought about 3betting big otf because he never lays down tptk w/ nfd, which is understandable

I thought my hand didn't seem that strong when I just called the turn and could get value on the river if it paired up. Also his turn bet was small-ish so it felt like a blocker or probe bet.

I thought the river was very good for me until he shipped 2k. How often is that a bluff with the betting patterns, and it almost was a bluff because I can only beat something like a Flush.

Anyways I think the Villain just spazzed out in the end, if he checked I would probably value bet around 1200 ish (pot was only 2k before his river shove).

It is such an easy call and really no need to tank for 5 minutes. The stacks are too shallow for you to fold your underfull plus it is live poker.

if this isn't a snap call in the game described against that opponent, its a call after about 10 seconds.

okay okay I get it, I kind of slow rolled him.. My first instinct was to call but I was trying to convince myself to fold because most of the time I call I feel like I"m beat...

You say the turn bet (1/2 pot) was smallish, but you're scared of a 4/5 pot bet ($2000 into a $2500)? You had to have known that was coming if you called the turn... unless you often see people betting 1/2 pot $1,250 and leaving $700 behind.

Yes your turn call makes you look weak, which is all the more reason you should be confident with your boat.

That river card is basically the best that can come... you drew out on a flush, and now all Kx hands are paying you off. If you're not willing to ship it with this river then you shouldn't call the turn. (just my opinion)
