Bridge Bidding Chart
Bridge bidding is a coded language. It helps to expect how the hand will play for choose the best contract. Each bidding system gave meaning to every possible call of the players.
Like this one creates language that allows to exchange information about the cards of your partner. The vocabulary limits to 38 different calls. Between them are 35 level bids except pass, double and redouble.
How to Bid in Bridge
A bid offers to play a sure contract. Contract defines a suit (or notrump), and the number of extra tricks. Those are the tricks above the book of six.
A bid becomes contract if three passes follow it. So each bid is possible contract. Bids rank also.
The lowest bid is 1♣. If you bid it and three others pass, the auction ends. Then clubs become trump, and you promise to take six tricks.
In bidding the main goal is find an eight-card or longer major suit between the hands of partners. Bids point where lie the points. In the cards are 40 points.
For example, AKQJ values 10 points. Descriptive bids do not ask anything. They show the new feature of the hand.
Like this one narrows the group of possible hands step by step.
Opening bids are the first bids other than a pass. A 1NT opening shows exactly 16-18 HCP, balanced hand and no 5-card suit. A balanced minimum opener (13-14 points) can use 1NT if lack a 4-card suit in your hand and no new 4-card suit at the 1-level.
For show stronger balanced hand you open 1NT with 15-17 points. For 1♥ or 1♠ you have 13-21 points and a 5+ card suit. At two five-card suits you bid the higher.
For 1♣ or 1♦ the points are 13-21.
Partners must know and agree about the meanings of bids before sit to the bridge table. Disagreements can cost them a good game. Many players use systems as 2/1 or Standard American.
In 2/1 a response in two above level forces to game. So such bid does only if the points of both partners are enough for game. Some players use weak 2 bids.
Strong 2♣ bid counts for any hand with 22+ points. 2♦, 2♥ or 2♠ show a nice 6-card suit, while other 2 bids are weak and lack a 4-card suit.
