Ok pf raise w/77?

[GoblinMason (Craig)]

BB, SB, and CO were fairly tight. Button was nice and fishy with 68/10/.5. I thought there was a very good chance raising would get me HU with him.

My main 2 questions are:

Is this an ok pf raise?

Also, is my fold on the turn ok being that he has a .5 aggression?

Preflop: Yes, I do this frequently. BTW, the next best alternative is folding.
I think you can fold the turn providing that you know he isn't tricky

Looks good. After lurking in the HUSH forum for a while, I've become a lot more comfortable open-raising pocket pairs.

Looks fine to me
