Event #5 $2500 NL 6 Handed

I got off to a great start in this event... despite drawing Jennifer Harman and Ralph Perry at my starting table. I won a few pots early and had it up to about 3300 when this hand came up in level 2... UTG makes it 150, Ralph calls on the button, I call from the BB with Kd3d. Its a loose call preflop - but when the flop comes 339 you look pretty smart. Anyway, I had played pretty aggressively
