Multi 2 Diamonds - Defences

Defences

• There are various popular defences to the multi. The method outlined below is not necessarily the best from a technical point of view, however it is perfectly adequate and has the advantage of being easy to remember.
  • Double shows a balanced hand with 13-15 HCP or any hand with 19+ HCP, with the range being clarified by subsequent bidding (the hand will usually pass if it has the lower range or bid again with the higher).
  • 2♥ and 2♠ are natural, showing 5+ cards in the suit bid and good opening bid values
  • 2NT shows 16-18 HCP and a balanced hand.
  • Other bids are generally strong (16+ HCP) following the principle that if the opponent's bid is weak, our bid should be strong.

• In general, when defending against a multi one should assume that the multi bidder has one of the weak options for his bid, since they occur much more frequently than the strong ones. It is also important to bid aggressively on the first round of bidding after the multi has been opened, before the opener's partner knows what type of hand he has.
