Bridge Conventions for Beginners: The First 5 to Learn, in Order
By Tracey Bauer
"Do you play Stayman?" It's the question I hear from students right after they've learned to open 1NT, and it stops a lot of them cold. A convention is an agreement you and your partner make in advance about what a bid means, on top of what the game already gives you. Learn five of them in this order, Stayman, Jacoby Transfers, Takeout Doubles, Negative Doubles, and Blackwood, and you'll have covered the auctions that come back again and again: after partner's 1NT, when an opponent gets in your way, and when a hand is good enough to ask about aces.
What a Convention Is
A convention takes a bid that would otherwise carry its natural meaning and repurposes it to ask a question or send a signal instead. A bid stops meaning what it looks like it means because you and your partner agreed in advance that it means something else. Memorizing the mechanics is the easy part; the harder habit is trusting the agreement in the moment, bidding 2♣ with a hand that would never open the bidding in clubs, and trusting that partner reads it the same way.
None of this is a rule of bridge itself. You can sit down and play a full session on natural bids alone, where every call means roughly what it looks like it means. Conventions get added once natural bidding runs short of ways to describe a hand. And because your partnership's agreements aren't visible to the opponents the way your cards are, the game requires you to disclose them. That's why some bids get alerted at the table: the opponents are entitled to know your side's agreements just as much as your own partner is.
If you're still finding your feet with the auction itself, the beginner's guide to how to play bridge is worth reading before this one.
Why This Order Fixes What You've Already Hit
Each convention below exists because of a specific moment at the table, not because a list says to learn it. This order follows the auctions a new partnership runs into first. Partner's 1NT opening comes up in nearly every session, so Stayman and Jacoby Transfers go first, because both are about getting more out of that one auction. Next come the two doubles, Takeout and Negative, because the moment an opponent bids, plain bidding tools start running short. Last is Blackwood, since it matters once a hand is already good enough to think about slam. If you came to bridge from Spades, bridge vs Spades covers what carries over from that game. By the end of this list, you'll have a plain answer ready the next time someone asks what you play.
| Convention | The Problem It Fixes, and the Agreement, in One Line |
|---|---|
| Stayman | You hold a four-card major opposite 1NT and want to find the fit before settling for notrump. The agreement: 2♣ asks opener for a four-card major. |
| Jacoby Transfers | You hold a five-card major opposite 1NT and want the strong hand hidden as declarer. The agreement: 2♦ shows hearts, 2♥ shows spades, and opener completes. |
| Takeout Doubles | An opponent opens, you have opening values, and no suit long enough to overcall. The agreement: Double asks partner to bid a suit, not to defend. |
| Negative Doubles | Partner opens, an opponent overcalls, and you hold the unbid major with values to compete. The agreement: Double shows the unbid major or majors, usually four cards. |
| Blackwood | The partnership is interested in slam and needs to know how many aces partner holds first. The agreement: 4NT asks; partner answers by count. |
Convention 1: Stayman
The problem: partner opens 1NT, 15 to 17 points and balanced, and you're holding a four-card major and 8 or more points. A plain 2♥ or 2♠ would promise five cards, so a natural bid can't ask the question you actually have.
The agreement: 2♣ asks opener for a four-card major. Opener answers 2♦ with none, 2♥ or 2♠ with one, and bids 2♥ first when holding both majors. 2♣ is a question about the majors, unrelated to clubs.
1NT - 2♣ - 2♥. Opener's 2♥ says "I have four hearts." When responder also holds four hearts, the partnership has found its fit two bids in, well ahead of where a natural sequence could get there. The full Stayman post covers the responses after opener answers, including what to do when opener bids the major you don't hold.
Convention 2: Jacoby Transfers
The problem: you hold a five-card or longer major opposite 1NT, and you'd rather the strong 1NT hand played the contract than expose it as dummy.
The agreement: 2♦ shows hearts, 2♥ shows spades, and opener is required to complete the transfer by bidding the suit named. Responder names the suit one step below the real one, and opener's completion carries no extra meaning of its own.
1NT - 2♦ - 2♥. Responder's 2♦ has nothing to do with diamonds; it's an instruction. Opener bids 2♥ on command, and the 1NT opener, not responder, becomes declarer in hearts. That's the point of the convention: the stronger hand stays hidden from the defenders. The full Jacoby Transfers post covers super-accepts and what changes with a six-card suit.
Convention 3: Takeout Doubles
The problem: an opponent opens the bidding, you have a hand worth opening yourself, but nothing long enough to overcall. Passing feels wrong, and usually it is.
The agreement: a double of an opponent's opening, made before your side has bid, asks partner to bid instead of defending. It promises support for the unbid suits and shortness in the opponent's suit. Partner is expected to answer; with 0 to 8 points, advance in the best unbid suit at the cheapest level, majors first.
(1♥) - X - (Pass) - 1♠. Partner's double said "bid one of the other three suits." With 0 to 8 points, advancer bids the best unbid suit at the cheapest level, majors first, which makes 1♠ the call here; a jump to 2♠ would show extra strength instead, about 9 to 11 points. This double works because it comes at a low level before your side has bid; a double made later in the auction, after your side has already shown a suit, can carry a completely different meaning, including penalty. The full Takeout Doubles post covers the strength and shape you want before doubling in the first place.
Convention 4: Negative Doubles
The problem: partner opens, an opponent overcalls, and you're holding four cards in the unbid major with enough to compete. A natural bid in that major would promise five cards, and you don't have them.
The agreement: after 1♣, an overcall of 1♠, a double shows four hearts. The double describes shape opener still needs to hear, without forcing you to invent a suit you don't hold.
1♣ - (1♠) - X. Responder's double says "I have four hearts and enough to compete," and leaves the level and final suit to opener. The point requirement scales with how high the overcall pushed the auction: about 6 or more at the one level, about 8 or more once the overcall reaches the two level, and about 10 or more at the three level, because opener may have to answer at that same height with a minimum hand. The full Negative Doubles post covers how opener's rebids change with a minimum, an invitational, or a maximum hand.
Convention 5: Blackwood, and the 1430 Keycard Version You'll Meet in the Workshops
The problem: the partnership has agreed a trump suit, the hand looks like slam, and now the question is whether the opponents can cash two aces before you get there.
The agreement: a bid of 4NT asks partner how many aces are held. Partner answers 5♣ with zero or all four, 5♦ with one, 5♥ with two, and 5♠ with three. Bridge Unleashed teaches classic Blackwood first, and then Roman Keycard 1430, the house version that treats the trump king as a fifth ace and can locate the trump queen too. You'll meet 1430 in the workshops once trump agreement and slam bidding are already comfortable.
1♠ - 3♠ - 4NT - 5♥ - 6♠. South, who opened the bidding, counted the combined points and the fit, asked with 4NT, heard 5♥ for two aces, and bid the slam. The full Blackwood post covers when to skip the question entirely, including voids and unbid suits with two fast losers.
Three You Don't Need Yet
Naming these now is meant to set them aside for later. You'll get to each one in time, just not this week.
Smolen. For when you hold 5-4 in the majors and game-forcing values after a Stayman sequence, so the 1NT opener declares responder's five-card major. Full Smolen post.
Michaels and the Unusual Notrump. For when you hold two long suits after an opponent opens and want to show both in a single bid instead of picking one and hoping. Full Michaels and Unusual Notrump post.
Lebensohl. For when an opponent overcalls partner's 1NT at the two level, and the partnership wants a way to separate a hand that's competing from one that's inviting game.
How to Write Them on Your Convention Card
Every agreement above goes on your convention card, in the box for that bid, because your opponents get to see it before the auction starts. Under the ACBL's Alert Procedures, Stayman, Negative Doubles, and Takeout Doubles are not alerted. Jacoby Transfers work differently: they're announced, so opener says "transfer" out loud when responder bids 2♦ or 2♥, rather than reaching for the alert card. The full guide to filling out a convention card walks through where each entry goes.

Frequently Asked Questions
Do I need conventions to play bridge?
No. A full session runs fine on natural bids, where every call means roughly what it looks like it means. Conventions get added once natural bidding runs short of ways to describe a hand, starting with the two auctions in this post: after 1NT, and when an opponent gets in the way.
What is the most common bridge convention?
Stayman, for most partnerships. Partner's 1NT opening comes up often, and holding a four-card major opposite it is common enough that partnerships tend to add the convention early, right after learning what 1NT promises and before they touch anything else on this list.
Are conventions the same as a bidding system?
No. A system is the whole framework: what your opening bids promise, how you value a hand, how competitive auctions work. Conventions are individual agreements layered on top of a system, the way Stayman sits on top of a 1NT opening that promises 15 to 17 points.
What is an alert?
An alert tells the opponents that a bid means something unusual they would not expect, so they aren't left guessing at an agreement your side made without them. Some conventions get alerted, some get announced out loud instead, and a few common ones need neither, because the meaning is treated as widely known.
How many conventions do tournament players use?
It varies by partnership and by the event's convention chart, which caps what's allowed. Many partnerships build a working set of conventions gradually over time rather than adding dozens at once, bringing in a new one once the earlier ones feel automatic.
