Should I be betting the with overs when I don't have the lead?

if it's HU, i bet all the way to the river. if not, i bet the flop and check/fold the turn UI.

There is also:
check-call
check-raise

Check-fold is standard here and the rest might be playable with good reads against certain opponents.

Either way. It's not good. Against most players.
