What does this bid mean?

[muronghan]

My thoughts of the bidding by North is as following, if the above auctions are natural and psyc. bidding is not allowed:

 

- Dbl= Just 4 cards of ♠ and may w/o ♦ support. A double after (1♣)-1♥-(1♠)-? can shows 5+♦ and certain ♥support which is normal. But after a minor suit overbid, finding ♠4-4 fit(or better) will be the first priority of heading for a game try or a partial contract. Therefore you may have to compromise not to disclose the length of ♦ precisely and immediately given the design of scoring system - Major is the King!

 

- 1♠= 5+♠s and I would like to treat it F1. Still can w/o ♦ support.

 

- 1NT= Natural; or very good ♣suit as alternative. I will choose it natural because staying at 1NT is usually cool e.g. in MP system even -50 will be scored nicely.

 

- 2♣= Good raise for ♦ and no interests in majors mostly, or a first step for a GF hand which is not shown in this list.

 

- 2♦= Just a raise for ♦ even with just ♠xx ♥xxxx ♦Kxx ♣xxxx. Of cause no interests in majors.

 

- 2♥= I like it as a natural bid, a strong 6 cards of ♥ and constructive but NF. Otherwise 5+♠s plus 3 cards of ♦ can be an alternative.

 

- 2♠= Fit Jump... BTW, I am always very happy when I can do so. Just one bid to show everything.

 

- 2NT= Good raise with 4 cards of ♦ can be an alternative but I would rather take is as natural and NF (in this case obviously the support of ♦ is still good). Simple reason: Trying 3NT first rather before 5♦.

 

- 3♣= Mixed raise, no interests in majors.

 

- 3♦= Preemptive raise, no interests in majors.

 

- 3♥= Splinter I will, implying some strength in ♣, so South can decide if shooting for 3NT. No interests in majors.

 

- 3♠= frankly speaking I can accept it as preemptive but for some reasons I prefer not as: 1. everybody has bid so the preemptive auction becomes dangerous and you never know if the opp has a game or not; 2. Perhaps always got a chance to interference given 7 cards of ♠; 3. opp has not found a suit fit yet and there is no evidence they will... therefore I would rather treat it as constructive, either Fit Jump or Splinter, or even can be Splinter for ♣ as 4♣ has bypassed 3NT.

 

- 3NT= To play.

 

All in all, a very interesting topic and I believe such auction process shall be discussed between the partners in a frequent way.
