I don't have problems betting after the flop when I have a hand like that, but when I bet and get called, or vice versa, then when the turn comes and I don't hit my straight, I have problems with whether to call big, big bets with just the river and only two possible cards to win. I would look at how pot-committed I am (How do I calculate whether I should fold at that time due to pot-committedness?). It seems that when I check to see the free card and then don't hit my straight, that I always hesitate to call after the turn because I don't know what my odds
are on calling considering how pot-committed I am.
Edit: didn't phrase my question well. Basically, in online poker I don't have much time to think about pot-committedness; is there a shortcut to know whether it is advantageous to fold to a certain mid-sized bet (with 3 players or 4 etc.). I don't have time to think about it, before I run out of time. I can call for time, but it doesn't help
