Theoretically, How Deep Before I Consider Folding This?

[Roadstar]

50NL 6 max

Table is Loose Passive.

Image - I could be seen as slightly LAG because I open raise in position more, I raise to punish EP limpers (at least 3 guys limp in EP on a regular basis) and I cbet if I'm the preflop raiser almost always - and these guys call preflop raise and fold. Not sure if guys notice but I still play big pots with big hands.

Stacks Hero ~$180, Villain around $100

Hero gets K [img]/images/graemlins/heart.gif[/img]Q [img]/images/graemlins/heart.gif[/img] UTG and raises to $2, folds to SB who calls (he is LPP, passive postflop too), BB folds.

Flop K [img]/images/graemlins/diamond.gif[/img]K [img]/images/graemlins/spade.gif[/img]2 [img]/images/graemlins/diamond.gif[/img]

Villain checks, Hero bets $4.5, Villain calls

Turn 2 [img]/images/graemlins/spade.gif[/img]

Villain checks, Hero bets $10, Villain raises all-in for $90, Hero must call to probably chop yes?

How deep before we would remotely consider folding here?
