K2s - Unsure on every street

[MCS]

Wynn $4/8 (4 handed)

We've just had like four people leave and are temporarily playing four-handed. All have agreed not to chop.

Villain is a thinking LAG who is borderline maniac preflop (he raises frequently from UTG and 3bet my full-table UTG raise with QTo) but plays the big streets well.

I have doubts about every single street.

Hero is BB with K [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/heart.gif[/img].

Preflop: CO folds, Button folds, SB says "you have J4, right?" and limps, Hero raises, SB calls.

Flop: Q [img]/images/graemlins/diamond.gif[/img] J [img]/images/graemlins/club.gif[/img] T [img]/images/graemlins/heart.gif[/img]
SB checks, Hero bets, SB calls.
