10-20 NLH -- Pot control v. value

[Rococo]

4 handed. I have $2300. Villain has me covered. I would describe Villain as relatively conservative. He is capable of bluffs and trickiness, but more often than not, his bets mean what they appear to mean. Villain probably views me as TAG. I haven't played many hands, but he has seen me put in a big reraise against another very good LAG at the table.

Folded to me on the Button. I raise to $70 with A [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img]. Villain calls in the BB.

Am I missing too much value by trying to keep the pot under control? I still feel like I am struggling to strike the right balance in these types of situation.
