Unbalanced 2♠

The invitational 1♥-2♠ is a multi-way bid. It has the following variants:

  • Unbalanced 3=♥
  • 5+ 4+ in minor suits, usually not 22(54)

With a minimum, opener tries to sign off at 3♣♦♥. Responder can also reevaluate after opener’s rebid.

1♥-2♠-UNBAL 9–11
2NTMIN, 0–3♦, 0–3♣
3♣♦MIN, 4+#
3♥MIN, S-SOL 6+♥
3♠!FG, ask for ♠ stopper

Thanks to this convention, 1♥-1NT becomes more balanced. Opener can judge more precisely when to pass.
