You're absolutely right about playing tighter with a calling station on your left. If they don't fold post-flop and let you draw, then limp a lot of stuff with potential, "semi-bluff" draws to build the pot, value bet TPBK, MP just don't let the flop get big. I guess what I'm saying is c-bet less, value bet more.
