party 30/60 top set butchered

[charlieD]

in this hand the player in the cutoff (38/18/2.3) has just joined the game and can be a bit of a loon. she tends to drive marginal holdings and draws a little too far.
the big blind is a little looser preflop (40/8/2) but has a style similar to the cutoff postflop.

on this draw heavy flop i decided to gamble, hoping that the cutoff had picked up something to go nuts with and allowing me to trap everyone else into putting in alot of money on the flop. was this a mistake?
