In general, I think low level penalty doubles are underused and with overcalls and preempts becoming lighter and lighter, they will inevitably make a comeback.
That said, the risk/reward at IMPS just isn't worth it, so I like to play takeout vs. penalty differently based on the form of scoring.
Does anyone else play something different based on the form of scoring? If so, what?
