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.
