Ive been at the table for 15 minutes when this hand occured:
ive got 200 and villian has same.
read on villian: call 15 and a re raise to 30 with 78off, hit two pair, and then bet out hard at the flop....probably laggish style.
i get dealt Q2 in the BB., there are a few limpers around, i check .
Flop comes : Q 2 6 raimbow.
i bet out 12.oo everyone folds to villian. villian raises to 30.
hero?

I'm raising, but how much?
