This is on ignition so there are no reads, I generally find myself confused here as I am never sure of V range. I try and convince myself I have them beat, and generally either call and have no idea what to do on the river, or shove and that is never correct.

Can you help me figure out what type of range V is in this spot considering completely unknown...

Should we even be calling the flop, like Ever? I realize its twice the size of the pot but for some reason find myself thinking this is a bluff. This is a huge leak spot for me and I'm trying to make sense of what it means. Any help appreciated...

Button ($4.78)

MP ($5.22)
CO ($12.42)

Preflop: Hero is SB with K, J
1 fold, MP raises to $0.17, 2 folds, Hero calls $0.15, 1 fold

Flop: ($0.39) 6, 7, J (2 players)

Turn: ($1.91) 7 (2 players)
Hero checks, MP bets $1.91, Hero ??

Not flatting this pre 3.5x vs MP, as played think we can exploitatively fold turns really hard to see many bluffs here with exception of perhaps T9dd 89dd A5dd with villain polarised to these and all overpairs/AJ/66/77

PF: In most spots, I play the SB with a linear 3-betting and no calling range at all. I deviate from it and become polarized when BB doesn't squeeze (either because he's a nit or a call-happy fish) and I have a decent implied odds hand which plays well in multiway pots.

When linear vs an MP open, KJs is a borderline case and it depends on villain if it's in my 3-betting range. When it is, one ought to be very mindful that villain's continuation range often dominates the hand so it can get you in tricky spots, particularly OOP (i.e. you can't pot-control as well).

When I decide to be polarized, KJs is in my flatting range but on a Kxxr board, MP villain has clear range advantage so play the hand accordingly. The reason to have it in your flatting range in such spots is really the BB fish who'll pay you off with worse Kx hands when MP gives up.

Flop: When readless, I'd assume such a flop overbet is usually for value. Though I've seen spewy fish do it as a bluff or with middle PPs like 88-TT in that spot. Vs an unknown OOP on such a board, however, I'd fold. While the betsize is a pretty good indicator that villain usually isn't a reg, I'd prefer to have some evidence that s/he is of the spewy/hyper-aggro variety who often overbets here with pure air (against such a villain, I'd be willing to bluffcatch 3 streets on many runouts). But without such reads, you have nothing but a bluffcatcher, clear range disadvantage and need to play in a bloated pot OOP.

Turn: As played, clear fold.
