A preflop decision that I didn't know how to deal with

[AlmightyJay]

I think some of my biggest leaks come from mid pocket pairs that I don't play ideally. Here's a situation that came up when I was playing yesterday. At the time I didn't know much about the villian, he had only sat down within the past orbit or so. I've got 58 hands with him now and he's 37.93/3.45/0.51.

I feel like this is a 3-bet or fold situation, but I don't feel comfortable playing a marginal hand like 88 postflop after I 3-bet. Advise me please [img]/images/graemlins/smile.gif[/img]
