Yellow Card Bidding System ● The partnerships want to play contracts in the following priority:
1) play a MAJOR suit contract first; or if not possible
2) play a NO TRUMP contract second; or as a last result
3) play a MINOR suit contract.
● After the suit or no trump is known, then determine the contract level to play.
A weak opening bid is for hands that have less than 12 HCPs and a long suit (6, 7, or 8 cards long). These are defensive bids because they can disrupt the bids the opposition can make.
