Defending: Strong Club Systems

   

Common Design Factors of strong club systems:

Nature of required defence to artificial opening bids

Our Defence Style

Against the strong club itself we employ a scheme wherein each intervention has  2 possible outcomes and deploy them as transfers to our partner, who relays and only then is the full meaning known.
Against their kind of multi  1 we use a sort of inversion of our actual hand - negatively showing our shortage first!
  1. This then mixed in with the oppositions need to unravel quickly - will do some of our work for us.
  2. Bear in mind too that if we inadvertently show shortage in their suit: this could spell a possibly bad break for them or pinpoint a ruffing opportunity for us!

Defending the strong club

When confronted with a strong Club opening BETA utilises a powerful and aggressive system known as TRAP. Since this is a 3rd party convention we are using, I house it with other conventions BETA uses. Basically each defensive bid of TRAP has two outcomes - only resolved on rebid while partner relays!

To confront the 1 opening we use a style of NOT showing what we have but rather showing what we don't have.
Its a philosophy of using a shortage to confront the unknown - aiming to make it more difficult to be resolved.
It cannot be comfortable to Precision bidders if we show shortage in their suit! They could easily be facing a singleton or even a void  hinting at a bad trump split.
Shortage in clubs is shown by 2 taking out a round of bidding - same with a 2 bid!
Our Multi 1N overcall covers 3-4 possibilities so again uncomfortable for the Precision bidder again seeing the whole of the 1 level removed from them which also gives away no information save showing at least 4 cards in Clubs!
Our overcalls are shown in order of preference is: (but we choose the most apt).
2 Shorter in Diamonds
2 Shorter in Clubs
1NT 9+ HCP and 4+ Clubs.- only the rebid will show more detail of the distribution - and thats perhaps after a further round of bidding! we use a sort of inversion of our actual hand - negatively showing our shortage first!
  1. This then mixed in with the oppositions need to unravel quickly - will do some of our work for us.
  2. Bear in mind too that if we inadvertently show shortage in their suit: this could spell a possibly bad break for them or pinpoint a ruffing opportunity for us!
