A lot of ranges need tweaking here to try and get to the more reasonable 5♦ (though still failing as cards lie) instead of the rather hopeless 6♦.
1- Should 3D really show 16-22?? To me, with the 2c free bid and the spade raise, I don't think it should really be that strong. Strong hands should double/bid 3S IMO. 3D should just show long diamonds IMO and min.
3d should only be 16+ if GIB wanted to play Good/Bad 2nt, which is probably too fancy for the general BBO pop.
2- 4C should have some upper limit especially if 3d is adjusted to be NF. If 3d is really supposed to be 16+ then maybe 4c should be F.
3- 4d surely should have some lower upper limit, 16-18 at this point if not less.
4- 4nt surely is too much, 5d should be plenty?

Try out Good/Bad 2NT* in competition.

After they bid to your right, 3D suggests 'jump rebid' values.

2NT* first and 3D next suggests minimum opening with long Ds.

  • For non-robot competition, a thread detailing contexts in which good-bad 2N applies and the nuances thereof would help me.
  • Anyway, I agree that neither 3♦ nor 4♣ should be forcing.
  • And 4♦ shouldn't promise the earth.
  • Gib seems reluctant to raise with a singleton; and seems to think that 4N (RKC) is a sensible alternative.
