Suppose East is known to have 7 spades from the bidding and after seeing dummy you deduce West to hold 2 spades; then if your two lines of play are to hope either for diamonds 5-3 or clubs 4-2, the a priori probabilities are 47% and 48% respectively but (,,,) % and (,,,) % so now the club line is significantly better than the diamond line.
The Baron Three Clubs is an alternative to the responder using Stayman over a 2NT opening bid. The responder will have five points or more and an unbalanced hand. The responder bids 3 ♣, which asks opener to bid his four-card suits in ascending order. If clubs are the only four-card suit, the opener bids 3NT.
The vocabulary of bidding is limited to 38 different calls - 35 level/denomination bids [1] plus pass, double and redouble. Any bid becomes a contract if followed by three successive passes, therefore every bridge bid is a potential contract. By the rules of the game, the agreed meanings of all calls must be public and known to the opponents ...
Ogust is a bridge convention used by responder after his partner has made a weak-two opening bid; its purpose is to gauge the strength of the weak-two bidder's hand. Named after Harold A. Ogust from the United States, the convention is also known as the 'Blue Club response' from the bidding system developed by Benito Garozzo.
This is a list of bidding systems used in contract bridge. [1] [2] Systems listed have either had an historical impact on the development of bidding in the game or have been or are currently being used at the national or international levels of competition.
At first glance, it may seem that the odds are now even, 1:1, so that South should expect to do equally well with either of the two possible continuations. However, the principle of restricted choice tells us that while both lies of the cards are possible, the probabilities are 2:1 in favour of assuming West holds Q32 and to therefore play the ten.
This is similar to Blackwood but the ace-asking bid is 4 ♣ rather than 4NT. The responses are 4 ♦ for 0 or 4, 4 ♥ for 1, 4 ♠ for 2, and 4NT for 3. Similarly, a 5 ♣ bid following an ace-ask asks for kings. Gerber is a jump bid to 4 ♣ used after a notrump opening bid and on other occasions by partnership agreement.
4 ♣ is Gerber if it is a jump bid or if a suit has been agreed as trump. 4 ♣ is Gerber if the immediate preceding bid by partner was in notrump. 4 ♣ is Gerber only if it is a jump bid over an opening bid or rebid of 1 NT or 2 NT. (Standard American Yellow Card) 4 ♣ is Gerber only when in response to opening bids of 1NT, 2NT or a strong ...
