[MLG]

I don't know if I would have played the flop that fast, but damn it looks like it worked. You now have 1000 in your stack and there's 3000 in the pot. I would just stick the last 1000 in on the turn and figure you'll get called in at least one spot. Incidently with two callers they are probably drawing fairly live against you (either to a full house, a bigger flush or both) so checking a blank on the turn is a mistake.
