Well, BB is very loose.

I figure if I check, LAG bets BB is likely to call and I can make the overcall.

If I bet, LAG raises BB will fold his marginal hands and I don't feel comfortable 3-betting with a weak ace, even vs a LAG. So now I have to call, risking 2 BB for 2 when I think I'm probably behind in this situation.

If I check, LAG bets, BB calls, and I raise, I'd really hate to be 3-bet here.

I dunno, I like the first situation. Putting in 1 BB to win 2 by check/calling. Of course if LAG checks, I get screwed.
