Defence to the multi 2 diamond
The 'multi' is becoming increasingly popular at club level.
Its meaning varies but it usually includes 'weak 2' bids in the major. (6-10 points and a six card suit). There can be various other meanings such as a strong no-trump 23-24 points and/or a strong 2 bid (8 playing tricks in a minor). Al lthese can be included in the opening 2 diamond bid. Still another option is to include 4-4-4-1 hands of 17 points or more. With all these possibilities it is difficult to defend against. That of course is the intention.
Given below is Ron Klinger's defence.
Over the 2 diamond opening:
Double = 16+ points any shape except for the 2NT and 3NT bids.
2NT = 19-21 points balanced 3NT = 22-24 balanced
Suit bids are natural but below 16 points. At the 2 level an opening hand with a strong 5 card major is ok.
At the 3 level a good 6 card suit and a 6-loser hand is needed.
After the double:
Bids at the 2 level are weak and non-forcing.
2NT is a 'puppet' bid to 3 clubs. This allows the doubler to show a weak hand in clubs or diamonds. When partner bids 2 clubs the doubler either passes or corrects to 3 diamonds with a weak diamond hand.
Bids at the 3 level are strong and forcing to game, normally 8 points or more. 3 hearts or 3 spades in response to the double shows a 5 card or longer major. With 8 points and only a 4 card major bid 2NT and after partner bids the (forced) 3 clubs bid 3 hearts or 3 spades which now shows only a four card major. Other bids after the double are 3NT = 4-3-3-3 and 8-11 points. 2NT then 3NT = 4-3-3-3 and 12-14 points.
After (2 diamonds): no bid: (bid). Treat the bid on your right as the opening bid. So, if the reply to 2 diamonds is 2 hearts, adopt the same defence as you would for a weak 2 bid in hearts.
