Strong hands are bid slowly.
Weak hands are bid quickly.
After the Game Forcing Single Minor Raise, most contracts
will be 3N.
Responder has denied a four card major.
Opener's first concern should be whether there are major suit stoppers.

Responder rebids should tend toward showing major suit stoppers responder has
denied, as well as showing/denying extras values.
In keeping with general principles of 'slow arrival', minimum hands should jump
to game.

What about the usual simple single raise (6-9 points)?
You don't really have one. The idea is to pre-empt or start a slam try at a
lower level.
If you had what was once a simple raise, you now have to choose between pre-empting
OR bidding a possibly atrocious 1N.
Perhaps that's one of the most important things to discuss with your partner.
Some of the best just refuse to play Criss Cross.
