one of my pupils has trouble remembering how many points she needs to raise a suit Playing Acol: to raise 1S to 2S she remembers she used to start school at 5 to 9 and to raise to 3S she remembers that break time was 10 to 11 it works with her :)

A local pair uses penalty doubles against weak jump overcalls and Take out doubles against intermediate or strong jump overcalls. They ask about the jump overcall, then double if it fits the criteria. Is this allowed under 40B3? I dont actually understand the difference between f & g actually. Can someone explain it please.
