DTD300 deepstack. My image is on the looser side I guess, opened quite a few hands in LP when folded to me but not getting OOL at all or getting many spots.
Played a couple pots without SD, one against villain. Also folded to a 3bet from villain once, when OOP. Villain is playing very aggro using his chip stack well. Saw him 3bet a bit and 4bet click fold.
We open to 6k at 1.5k/3k with

from BTN Playing 117k , Villain covers.
Villain 3bets SB to 16.5k....
We call (1st Discussion point

) --- Reasons for calling are - I just thought his re-steal range was v wide (how he'd been playing) + the stacks were good for him to 5bet bluff all in, so peeling IP with a hand that flops well and will flop draws I can aggressively semi- bluff with 34bbs back, seemed OK. 87ss Is by far the worst hand I would do that with. Normally it will be like 87ss+ and Suited broadway. Some of the time, importantly, not all the time and only if I think It's a good spot. EG, aggressive player with high/v high re-steal from SB/BB, IP, heads up, that is able to identify light 4bets, use his stack and 5bet all in lightish. Is this a mistake? Anyway, I'm sure you will all tell me.
Villain also gives some speechplay whilst I was dwelling for 20 secs... Strange one

... ''26,300/call, 26,300/fold, What's it gonna be?'' Not sure what to make of that. Felt like he was planning on 5bet shoving for some reason in my head, maybe read it wrong.
-- FLOP --

Villain checks, I bet 15,300, (thoughts?) I'm assuming villain never has a flush draw here as he would lead like 95% of the time with his equity I think? My plan was to fold out all broadway that is almost certainly check folding this flop, Apart from maybe JT with the

that might CC? Who knows? Planning on shoving if villain check raises here, that's why my bet size Is that small to try and induce. I doubt he will do this very often but meh.
--- TURN ---

Villain checks, I check back (thoughts?). I just thought it was check or Bet/call. Guess i wimped out a bit but still couldn't really pinpoint a range the villain had? So I thought I'll check. See a river and re-evaluate.
--- RIVER ---

Villain tanks for like 90 secs at least and then bets 36,300. I tank fold

(thoughts?). Felt like he was at it SO BAD. Thought about jamming,calling and folding. Then again thought he could easily have AJ, JJ, or even JT. So, in the end, decided I'll take my 20BBs and live to 3betshove another day. Thought he could turn hands I can't even beat into a bluff too, also he could have a 6 that's flopped pair plus and CC'd? MEH, guess I'd love to know what you think about every street gents!
Sorry about the length of this just wanted to put in my thought process so you could identify and crush any flaws

Thanks for reading, guess not sure about any street fully, would really appreciate any help!
