Yes I understand, my question was poorly phrased. I hear some treat the 1M opening as "likely 5 cards", I don't really understand how they play this. We still don't want to be pushing to the 3 level on a weak 4 card raise.


I prefer to play 4 card majors (and do so with a major's first opening style so we open with a 4CM lots of the time

We happily raise to the 3 level with 4 pieces.
It works out fine.
4-4 fits play really well and, if we're higher than the LAWS suggests, well its not like the opponent's know whether we're in an eight card fit or a 9+ card fit.

I can’t speak for others but from my experiences a true 4-card major devotee will open 1H holding xx, AJxx, KQxxx, Ax so the issue becomes how to take preference when responder is weak and 2-2 in opener’s suits.

The issue 4-card majors solved is always having as opener a rebid. More often than not a major opener holds 5 even playing 4-card majors. Bergen can be used as long as you realize the occasional 4-4 fit won’t be LOTT protected

Thanks. So there seems to be no reason we shouldn't continue with 1M:3M preemptive, and Bergen style raises. Opener can put the breaks on with a 4-4, as opposed to a 5-4 fit.

O utred methods...

1 -
  • 2 = ART REL (Opening values).
  • 2 = ART 3-card raise 8+ HCP.
  • 2/3/4 = PRE 4+ card raise.
  • 2 = ART 4+ card raise to 3/5. 2N asks. Then 3/3/3 = SPL singleton //.
  • 2N = ART 4+ card raise to 3/5. 3 asks. Then 3 = BAL 4-card raise, 3 = void .
  • 3 = SPL 4+ card raise to 3/5 with void .
  • 3 = SPL 4+ card raise to 3/5 with void .
  • 3 + = Similar to above with good raise to 4.

  • 2 = ART REL (Opening values).
  • 2 = TRF 5+ .
  • 2 = ART 3-card raise 8+ HCP.
  • 2/3/4[4SP = PRE 4+ card raise.
  • 2N = ART 4+ card raise to 3/5. 3 asks. Then 3/3/ = SPL singleton //.
  • 3 = ART 4+ card raise to 3/5. 3 asks. Then 3 = BAL 4-card raise, 3 = void .
  • 3 = SPL 4+ card raise to 3/5 with void .
  • 3 = SPL 4+ card raise to 3/5 with void .
  • 3N+ = Similar to above with good 4 card raise to 4.

Features:
  • Comprehensive, consistent and simple.
  • Distinguishes pre-empts, game-invites, and slam-tries.
  • Distinguishes 3-card from 4-card raises.
  • Distinguishes balanced raises from splinters.
  • Distinguishes singletons from voids.
  • Opener can sign-off or bid game without needing to reveal responder's singleton.

As somebody who plays a canape system, that is a very legitimate question about making the right preference. Sometimes you will get it wrong. You can reduce some of the guesses by introducing some complexity.
