8 players post ante of 0.13 BB, SB posts SB 0.5 BB, Hero posts BB 1 BB

Pre Flop: (pot: 2.5 BB) Hero has K 9

fold, fold, fold, MP+1 raises to 2.25 BB, fold, fold, SB calls 1.75 BB, Hero calls 1.25 BB

Flop: (7.75 BB, 3 players) J 4 5
SB checks, Hero checks, MP+1 checks

Turn: (7.75 BB, 3 players) A
SB checks, Hero checks, MP+1 checks

River: (7.75 BB, 3 players) J
SB checks, Hero checks, MP+1 bets 5.89 BB, fold, Hero calls 5.89 BB

So, I don't think that V has any value hand because he didn't bet OTF and OTT.
From the remaining range I lose to KQ and KT but beat K8, Q9, QT, T9, 98, 87(50%)
So, it seems to be +Ev call.

Any comments on this? TIA!

Seems fine, I mean, you've got a pure bluff catcher here (you never beat value and you always beat bluffs). Saying he has no value doesn't seem right though. His value range is probably some hands with 5s and 4s in them, maybe 66, 77, 88. He will also have some strangely played jacks (I can see someone thinking "I need to check back some jacks, this one seems fine" then seeing the Ah turn and going gross, and betting the good river after you've checked twice on the flush board).

The bet size from him seems about right for this range. I might even size it up a little -- you're pretty darn capped at this spot so a large bet is probably okay.

In a 3-way pot he can definitely have a stronger check back range. We definitely don’t have to call since we have a lot of way stronger hands in our range here.

So I wouldn’t do it readless.

what hands with 5s, 4s he has in his range? A5s and A4s bet OTT, don't they?
Also, I am not sure if he checks back with 66,77,88..I would bet with them for protection while it's only 1 overcard on the board...
What about 22, 33 though? Would he play with them like he did?

He could have a J with weaker kicker he checked back or an A he chose not to bet ott. Sizing looks value oriented. With hands with no showdown value he could have tried to take down the pot earlier. I would like to have a read that he likes to bluff before calling down with K high.

Right, this line with Jx seems convincing, but with 2 jacks on the board the amount of Jx combos he might have is severely reduced. 9 in our hand also blocks some J9 combos.

We don't have any reads on this guy other than

[P] 3Bet All-In (Eff. Stacks: BB between 5 and 20) with {KK} (1)
[P] 3Bet Not All-In (Eff. Stacks: BB >= 10) with {TT} (1)
[P] Called a 3Bet Out of Position (Eff. Stacks: BB >= 15) with {T7s} (1)

His stat's sample size is only 25 hands, so no reliable conclusions can be derived..

He had 98d by the way

dont even hate it that much, might potentially be a better call than some 4x combos.

Okay, it seems that the most important outcome of this hand is in that we need to somehow make sure that V is capable of bluffing in order to call OTR in this spot..
I recently saw a funny relevant* tweet from Chris Kruk(very good player):
