2NL 6m bottom set faces turn c/r 200bb deep

Villain is 23/15/2.2Agg over 350 hands, 2.7% 3b, 24% steal, 65% cbet, 24% WTSD, 56% W$SD

In other words pretty decent winning player, pretty straightforward, does not seem to get much out of line. The VPIP/PFR gap shows he likes to limp behind or call with speculative hands like small/mid PP or suited connectors, and that is indeed very profitable at 2NL especially in the Party Poker fishpond.

The other villain is 30/30 over 10 hands. Stupid preflop minraises show he must be bad.

BB ($5.69)
Hero (Button) ($4.03)
SB ($2.74)
UTG ($1.48)

Preflop: Hero is Button with 4, 4
UTG calls $0.02, Hero calls $0.02, SB bets $0.03, BB calls $0.02, UTG raises $0.04, Hero calls $0.04, SB raises $0.04, BB calls $0.04, UTG calls $0.02, Hero calls $0.02

Flop: ($0.32) 4, Q, 9 (4 players)
SB bets $0.15, BB calls $0.15, 1 fold, Hero raises to $0.45, SB calls $0.30, BB calls $0.30

Turn: ($1.67) K (3 players)
SB checks, BB checks, Hero bets $1.59, 1 fold, BB raises to $4.77
($1.91 behind)

My flop raise is too small (which makes me realize that the bet buttons on PP do not work as they should). I meant to do a half pot raise, which should have been $0.54 or so. Even that is probably still too small, but the flop is rather dry.

Not sure if I should pot the turn.

Vomit and fold to his c/r?
