Hi guys, lurked a long-time before finally posting but hoping for some help on this MTT hand.

New table, minimal info:
Villain (BB) - 113bb stack
Me (LJ) - 94bb stack

UTG min-raises 2x, I call in MP with ThTc - a hand never usually in my 3-bet range.
Folds to Villain in BB and he makes it 6x, UTG calls and so do I.

20bb pot including antes. Flop:
6s 3s 2d
Villain C-bets 11bb, UTG folds and I call. No other play here IMO, I think Villain does this with 90%+ of his range.

42bb pot. Turn:
6s 3s 2d - 9h
Villain continues for 25bb. I call - again, not sure there's any value in raising and I'm not folding.

92bb pot. River:
6s 3s 2d - 9h - 8s
Villain checks and I shove my remaining 52bb. Villain tanks for two minutes and calls with Js Jh

Here's my thinking: small 3-bet pre-flop so could be quite wide but given it was over an UTG raise and call, I put Villain on TT+, AQ+. I think the C-bet is standard but the turn bet is slightly more worrying. Would he double-barrel AK/AQo without a spade? What about with the As Maybe... so I narrow his range to JJ+ (I block TT and they probably check back turn) and then the river checks makes me think he has his face up as JJ/QQ, hence my shove. It's a great call.

My question is did I play it fine to rep big on the river to fold JJ/QQ? I can have 66-JJ in my range. Plus maybe As Ks, As Qs, As Ts, all of which beats his hand. I guess I'd have raised flop or turn with 66/99 and he knows that. I feel like not much else I can do here to get JJ to fold and maybe Villain would've folded if he didn't hold Js.

Thoughts appreciated on my ranging, line and shove

Think it's fine, suprised villian isn't shoving the river here given board texture and how the hand played out. I disagree with your thought process, I think villian can be giving up here, I don't narrow him to QQ plus, I think he can have some bluffs, some AQ, AK, KQ, KJ type spade draw hands that might double barrel. I think if your shoving, your shoving for value. If you think he has QQ-AA, this isn't the board to get someone to fold those hands, and doubt many villians at small stakes would ever consider folding.

I don't think the shove makes sense either as value or bluff- it's hard to see much that is going to 3bet pre and then double barrel and check /call which is worse than TT but many Vs will take this line with hands as strong as AA when the flush comes in -
I guess there may be some times when JJ -QQ will fold but not enough

Sorry I misread the hand. I didn't see the river was a flush. I think it's a check back spot. Villian has to think you might reraise the flop a good percentage of the time with your two overs and flush draws (which is what you are repping by your jam). I'm not sure your getting JJ-AA often enough for the bluff to be profitable.

Don't try to get people to fold overpairs for 0.5psb

Our hand def has SDV vs V's bluffs. I don't see the point in bluffing this particular combo. Would much prefer bluffing with a spade blocker.

"Villain C-bets 11bb, UTG folds and I call. No other play here IMO, I think Villain does this with 90%+ of his range."

It is very dangerous to think like that. You don't have any info. Why so sure!? What is his range PF then!? You don't know, no one does. For the flop as well...If you know about this "~100% Cbet", then you have a very profitable call. But I don't think so. Most likely borderline call. And 44, 55 will be better here. Than TT...

OTT I will fold. You have "a light call", borderline call OTF, then fold OTT vs this size. Imo...
As played, OTR you just can't shove. With bluff catcher . Just check-back...

Oh, you are bluffing. Don't do that , mate. Why? If you want to bluff, then shove OTT. But...With this hand...I can't find worse hand to do that. Maybe TsTc . What is the buy in? "Small stakes MTT". You don't like the 3bet PF, but you do such a things. I don't know. I don't like it..."It's a great call." Mate, stop watching videos in Youtube and play more simple. The people are "simple", no need for this. No offence...
