Hero is BB, Villian is button. Villian a couple orbits earlier raised BB 3.5x with 97. Hero called w/ 66 and flop comes 7-7-3. Hero loses some money.

Now -- villian raises 3.5x. Hero calls w/ 7-5o.

Flop: 8-6-3

Hero check. Villain pots. Hero raises 3x. Villian raises another 2.5x.

Hero?

(better line just call flop bet?)
