We open ALL hands between 7 and 13 hcp. We pass ALL hands 0-6 or 14+ (1st and 2nd seat).

When we open, we usually show the exact number of cards in a major (or both). Usually we deny length in the other major. Exception: the 1c (in 1st and 2nd) and 1h (3rd, 4th) openings can contain also 4 spades (if 11-13 hcp). When we open a minor, we deny lenght in both majors (0-3 hearts, 0-3 spades). With a 4 card major and a longer minor, we always open with the major.

  • new suit = natural, can be very weak, partener should cue-bid if 14+
  • lowest NT available = 16-18 bal

• Any subsequent action from the initial passed hand shows 14+
  • Exception 1: fit bids where a cuebid was available below game level

  • 2s does not promise anything about spades, but partner must pass
    • subsequent double
      • 2nt = bid your best minor
      • 3c, 3d = absolutely to play, no questions asked

use 2s as an escape sequence when we get doubled in 2h and partner has something like 2-1 majors

• They overcall 2s or 3h natural
  • dbl = take-out, probably 3 cards in the other major, singleton or void in this one
• They overcall a minor
  • dbl = see the 2-under double after a natural overcall (proposing penalty if partner is not singleton)
