I have 3000 chips and get dealt Q Q on the button, blinds are at 40 80.

1 person folds,

I raise 400 from the button. Sb folds BB calls,
flop comes

8 6 6 multi colours.

I bet 600, after sometime BB goes all in. Which covers me.

what do i do?

bb is loose as a moose, the stack size av stack size is 2700 3000,
last 2 hands Bb went all in on was ace 10 on a mega bluff on the river and j8 on the flop with nothing.

i did, and he turned over king 6 i could of cryed i just needed conformation i didnt make a donkish move.
I couldnt put him on king 6 or a 6 with a big raise in front pre flop ace 8 was the hand i had him with.

Nothing you could do there, his loose image was his advantage this time. Good players who use a very loose style get paid off huge when they hit a monster (bad players do too but lose more when they don't hit )
