What I am saying is that you can, for example, play 3red as 5+ GF and X then bid the major as invitational with 5+. Or you could play 3red as 6+ INV+ with X then bid the major as INV with 5 and X then cue as 5 and GF. Whichever way you define the 3red bids, you have additionla hands leftover which can be defined by doubling and then bidding. This allows you to keep your NFB purer, which I think is a good thing, especially in a Precision context.
What is 3red ?
