Bridge bidding looks like code. Four players, a box of cards, and a language of numbers and suits that seems to assume you already know the answers. You do not, and that is fine. Nearly every strong player started with two or three rules and repeated them until they stuck. What follows is a single auction, ten calls long, explained from the first bid to the final pass. Read it once, then deal a hand and try it.

Every call is a bid, a pass or a double

A call is simply anything you say when it is your turn. That includes passing, which is a real call with real meaning, not a shrug. Bids name a level from one to seven and a strain: clubs, diamonds, hearts, spades or no trumps.

Higher levels outrank lower ones. Among bids at the same level, the strain order runs clubs, then diamonds, then hearts, then spades, then no trumps. So 1♠ beats 1♥, and 2♣ beats 1NT. Doubles and redoubles also exist, but a beginner's first auction rarely needs them.

One rule governs everything else: the auction ends when a bid is followed by three consecutive passes. The last bid made becomes the contract.

Count two things before you bid

Points and shape. Points first: ace four, king three, queen two, jack one. A full deal contains 40, so an average hand is about ten. Then shape: how your thirteen cards divide between the suits, and how long your longest suit is.

  • 12 or more points: you may open the bidding.
  • Fewer than 12: pass and wait.
  • 6 or more points: you may respond if partner opens.
  • Balanced hand, 12–14 points: many British club players open 1NT, the Acol weak no trump.

That is the whole foundation. Everything below is those two numbers applied in order.

Calls one to four: open, pass, raise, pass

North deals and holds ♠ A Q 7, ♥ K Q 10 8 5, ♦ A J 6, ♣ 8 2. That is 16 points, five hearts and no longer suit. Call 1: 1♥. Why hearts? It is the longest suit. With two five-card suits, bid the higher-ranking one first, which keeps the auction flexible. If you play Acol, a one-level major opening promises only four cards, so opening 1♥ on five is comfortable.

Call 2: East passes. Nothing to say, no points worth mentioning.

Call 3: South bids 2♥. South holds ♠ K 8 4 2, ♥ J 7 4, ♦ Q 10 8, ♣ K 6 3 — nine points, three trumps, a flat hand. Partner has shown hearts, so South has support. The single raise says precisely that: three or more trumps and 6–9 points. It also warns North to slow down unless the opening was strong.

Call 4: West passes. Both opponents passing does not change your own obligations. You simply describe your hand when your turn comes round again.

Calls five to seven: invite, pass, accept

North now knows the partnership holds somewhere between 22 and 25 points. A heart game needs roughly 25 combined. That is too close to call, so North asks rather than guesses. Call 5: 3♥.

This is an invitation, not a command. It means: "I have about 16 points and a fit. Bid game if you are at the top of your range." Because South's range is wide, the decision belongs to South. That is the point of the sequence — one player asks, the other answers.

Call 6: East passes. Call 7: South bids 4♥. Nine points is the maximum of the 6–9 range, and the ♣K and three trumps are working cards. With a bare six points instead, South would pass 3♥ and the contract would stay at 3♥. Nothing is wasted and nothing is guessed.

Calls eight to ten: three passes and the play begins

West passes, North passes, East passes. Three in a row after 4♥, so the auction is closed. North is declarer because North's side bid hearts first, and East, sitting on North's left, makes the opening lead. From here it is card play, not bidding.

What if the auction dies earlier?

Had South passed 3♥, the last bid would be 3♥ and the same rule applies: three passes, contract set. The pattern is worth remembering, because it catches out new players constantly. The contract belongs to the side that bid the strain first, and the defender to the left of that player leads.

The beginner's cheat sheet

  • Opening: 12 or more points, bid your longest suit; with 12–14 balanced, consider 1NT.
  • Response with a fit: 6–9 raise to the two level, 10–12 jump to three, 13 or more bid game.
  • Response without a fit: a new suit at the one level shows 6 or more points and at least four cards; 1NT shows 6–9 with no fit.
  • Opener after a single raise: pass with 12–14, invite with 15–16, bid game with 17 or more.
  • Three passes end the auction. Always.
  • Count points, then count trumps. Long suits and ruffs beat scattered honours.

One caution: bidding systems differ. Acol, Standard American and five-card-major systems treat some openings differently, so agree with your partner before you sit down and ask what your club plays.

Practise one auction at a time

Deal thirteen cards to each of four players and bid only the auction above, whatever hands you actually hold. Notice how quickly the meaning becomes automatic once the same sequence repeats. Then swap the hands and try it again with weaker and stronger responding hands, so you feel where the 6–9 boundary sits.

Resist the urge to collect conventions. Beginners who learn Stayman and Blackwood in their first month usually bid worse than those who simply count points and trumps accurately for a season. Get the ten calls in this article right first, then add one new idea at a time.

Afterwards, play the hand out. If 4♥ fails, ask whether the bidding was reasonable rather than whether the cards were cruel; sometimes the right contract goes down, and that is not a mistake. If it keeps happening, look at your point counts and trump lengths before you blame your luck or your partner. Bridge rewards patience far more than cleverness.
