2♦ multi : Opening 2♥ and 2♠
These bids are used to describe a weak two-suiter. Various systems are possible : Dominique suggests :
  • 2♥ showing a weak major two suiter 5-5 or sometimes 5-4 (but then not minimum points)
  • 2♠ showing a weak two-suiter with 5♠ and a minor with at least 4 cards
  • The strength of these two-suiters varies between 4-9HCP
