Common scenario that I don't know how to deal with.

well, why isn't calling an option? if you bet 30, he raises to 100 you call. then a flop bet of 200 (i just wrote the bet sizes down to show that you're not really pot comitted if you call. the bets are still not huge.),

calling is certainly an option with position on your opponent. calling out of position and checking the turn is going to leave you in a spot where you will not win the pot enough times to make the call profitable.
