I'm around 10th at this point, 140 left, par 17k. I have a few notes on villain. When he just calls a PFR (which he does a lot), he very frequently minbets the flop. I saw him min bet-min bet-min bet with a crappy turned 3rd pair, so my assumption is he min-bets most flops, then min-bets turn and river as blockers. He's unsophisticated, because he does a lot of open-limping in the CO/BTN and minraising everywhere. I've stolen the blinds twice in the past orbit.

Thoughts? Assuming I decide to try to win the pot, is this the best way to go about it? What range is a typical so-so player calling with on the river?
