Hi guys

So, it's early in the day 2, Vilain doesn't know me, prob view me as a random playing tight scared money, no history, first level of day 2. He hasn't been crazy for now, opening a lot ip but pot controlling flops a lot.

Vilain is Jacob Rasmussen.

It's not exact sizings but should be close to what happened.

So, we both had ~80K, blinds are 250/500, not sure but antes were prob 75.
He's not gonna open much lighter than usual here since big blind is top mtt player with big stack.

Vilain opens hj to 1K, I call BTN with 9s Ts , SB and BB call

Flop : 9h Td 4c
Everyone check to me, I bet 2K, blinds fold, he calls

Turn : As
He checks, I bet 4K, he raised to 10K, I called

River : Kh
He bets 18K, I ?

18K otr is not pot control, its a value bet. Fold.

I know it's not a pot control !
I know his value range beat me on the river, but I can't really see which hand he's playing like this (A4 ?) and which hand he's turning into a bluff. I don't understand anything about his line.

completely agree with OP, the only thing that makes sense here is A9/A4..but i think you will see those two hands a lot. After you call turn, he has little reason to believe you will fold river... which of course makes me want to tank fold river

In not the main event I might shove the river, but as played i'd fold. I'd consider folding the turn, but i'd never actually do it.

Don't you think he's more likely to lead the turn with aces up ?

That depends on you. a c/r is very likely if he fully expected you to bet/barrel the turn.

he called flop and check-raised river. I think He had some part of the flop and it improved on the turn - such as A9 AT A4. or he min raised pre with aces. or he check raised turn to try to get you to fold so he didn't have to hit his str8 draw and now he actually hit his str8 draw. A9 and AT are a little less likely since you have 9T.

there's just too much out there that beats you. find a better spot. fold.

Or had AK/QJ and was just doing pot control. Raising to 10k on the turn would make you seriously consider checking behind on the river without a very strong hand. Then of course he value bets the river after he gets there.

doubt he ever has a4 here(maaaaybe a4hh/dd), and even a9 shouldnt check the flop close to 100% 4way(perhaps like 65%),while the fewest ppl c/c QJ here otf he might be doing it sometimes-often based on description.but if some1 is ever bluffing here he has to have exactly 8x/KJ i guess.

this thought process works for AK but, what showdown value would qj have if he misses?

I think he's betting QJ a high percentage of the time otf. I really doubt he would use this line with JQ ever.
I think he can check A9/A4 otf more often.

I really felt that this king on the river was the worst card to bluff on and this spot was unbluffable.

He can think I'm taking a stab on the flop ip with any 9 T or str8 draw and just barrel a scary turn

What is my perceived range otr ?

Thinking about some more, he probably had a set and hoped you had an Ace.

player dependent. fold against most obv
