10/20 6 Max. (4 handed)

This game doesn't run often on this site. Villain is a weaker reg who I don't play with often. The 8 or so orbits we had played so far villain standard open was $60. At this point he was playing pretty straightforward and not being too aggressive.  I am very unclear of what his is 3b defending range is here being this deep. 

Do you like the line I took here up to the river? Is the river a call or a shove? 

165bb Effective.

Co folds, Btn raises to $70, Hero raises AA to $210, BB folds, Btn calls. 

Flop (Pot: $440): 8c 7d 6s. Hero checks, Btn checks.
