2-over-1 showing 10+
Rules:
* 2NT is always GF
* Raising opener's 2nd suit is forcing
* Raising responder's suit is forcing
* Rebidding 3m is nonforcing after opener's possibly minimum rebid
* Rebidding the opening suit shows a minimum (NF)
* Giving preference on the 2-level is NF
* Raising a nonforcing 2M to 3M is invitational

3♦: Balanced, 3-card x
3♥: 14 - 16, 6M
3♠: 16 - 19, 6M, not so good suit
3NT: Balanced, 2-card x
Respond 1NT on 10-11 hands that do not have a rebid after a minimum from partner, i.e.

This seems to have been written for a standard system. Are there any adaptations for limited openings?
I suppose it's possible to just scale down the HCPs in case of the jumps, but there are other sequences that would be awkward...

I've of the play standard over Precision versus 2/1 GF because of the many bad results I had with a 10 opposite 12-13. :-)

I guess I would start playing 1M - 2x - 3x as nonforcing and replace the big 1-suited hand in 2NT with the forcing unbalanced raise.
