Strange small blind question, PP 50-100

[Turning Stone Pro]

Strange little hand. I'm in the SB with K7o. Folded to the button who merely calls (vpip 29, appears to be a below average player, not especially aggressive or passive). The BB is a solid player, vpip 24 or so.

Question #1. Call or fold pre-flop? (1/2 blind structure)

Let's say I call.

Flop is A89r. I check, BB checks, button checks.

Question #2: Turn is an A. your move?

Thanks!
