$25NL 6max Bodog, no converter as I haven't got the handgrabber yet, sorry!

Villain has been fairly active preflop, isolating the limper he has position on often. I've not seen many of his showdowns, but did notice when villain was isolating a limper he raised to $1.10, and normally opened for $0.85, but saw him open once for $1.20 with KK, so perhaps his raises are a bit bigger with bigger hands, perhaps not.
I've not had much chance to 3bet him, rubbish cards and playing a little tighter cos I've just moved up.

Villain has $41.68 I cover

Preflop, Hero otb has
Fold, Villain raises $0.85, fold, Hero raises $2.90, fold, fold, villain calls

Flop ($6.15)
Villain checks, hero bets $4.50, villain raises $14.00, hero?

$9.50 to hero, and nearly a full buy in behind after that.

Preflop?
Yeah I got a bit lost on this one, probably should have thought of a plan before 3betting him!
What to do on flop and plan for the rest of the hand?
