Drury Convention: How Passed Hands Explore Majors Without Getting Too High

You've passed in first or second seat. Partner opens 1♠ in third. You hold ♠KJ85 ♥A73 ♦Q964 ♣K2 — 11 HCP and four-card spade support. You want to raise, but a jump to 3♠ would be pre-emptive (6-9 HCP with 4-card support). Bidding 2♠ is a minimum raise. What do you do?

Without a convention, there's no way to show "I have a limit raise — 11 points, four trumps — in a passed hand." The Drury convention solves exactly this problem.

Drury is a 2♣ bid by a passed hand in response to partner's first or second seat major opening. It says: I have 3+ card support and limit raise values (10-12 HCP). Tell me about your hand.

The Problem Drury Solves

In first and second seat, bidding is standard: responses to major openings have their usual meaning, and a 2-level response shows a full opening hand (in 2/1) or 10+ HCP (in SAYC).

In third seat, the opening bid is different. Partner has already passed. They can't have a full opening hand — at most, they have a sub-opening hand with a good major suit. Common third-seat openings might be 9-11 HCP with a good spade suit, or 10 HCP with 5 hearts. The bid is strategic: take away space before you lose it.

When responder has limit raise values in this situation, the risk of standard methods is clear: if you respond 3♠ (standard limit raise), you're at the three level with a partner who may have only 9 points. That can be a disaster. If you respond 2♠ (simple raise), you've undersold your hand.

Drury threads the needle: bid 2♣ to show limit raise values, and let opener declare whether to accept or sign off.

How Drury Works

The key: opener's 2♦ rebid is artificial and shows a minimum hand. It says "I was light — sign off in 2 of the major." Responder then bids 2♥ or 2♠ and the auction ends.

Any other rebid shows extras and invites game.

Standard Drury vs. Reverse Drury

There are two common versions of Drury, and partnerships need to agree which they play:

Reverse Drury (also called Two-Way Drury) distinguishes between 3-card and 4-card support from the start. When responder has four trumps, they bid 2♦ instead of 2♣. This lets opener know about the 4-card fit immediately, which matters for game and slam evaluation.

Most 2/1 partnerships play Reverse Drury. If you're just learning, start with basic Drury (2♣ for any limit raise), then add the Two-Way version once you're comfortable.

When Does Drury Apply?

Drury is specific: it applies only when:

1. You are a passed hand (you passed in first or second seat)
2. Partner opens 1♥ or 1♠ in third or fourth seat
3. There is no interference between opener and responder
4. You have 3+ card support and limit raise values (10-12 HCP)

Complete Auction Examples

Example 1: Opener Declines Game

2♠ is the right contract. Without Drury, North would have to bid 3♠ (limit raise), landing in a contract that might fail when opener has a light hand.

Example 2: Opener Accepts Game

4♠ making. Opener's 3♠ rebid shows enough to accept the game invitation. North completes to game.

Fourth-Seat Openings and Drury

Drury applies in fourth seat too. When the auction is Pass — Pass — Pass — 1♠, the opener is in fourth seat. Responder can still use Drury to show a limit raise — the convention has the same effect.

Fourth-seat openings are somewhat stronger than third-seat openings (you don't open weak in fourth seat — no preemptive value if everyone else has passed), but the risk of overbidding still exists with a passed responder holding limit-raise values.

Drury in Competition

If an opponent overcalls between opener and responder, Drury is off. The auction Pass — 1♠ — (2♥) — 2NT might now be natural or something else entirely, depending on partnership agreements. Most pairs use negative doubles or standard competitive methods in this case.

Why Drury Is Essential for 2/1 Players

Drury fits neatly into the 2/1 framework because it handles the one situation where 2/1 doesn't apply: passed-hand responses. In standard 2/1, a new-suit two-level response is game-forcing (12+ HCP). But passed hands can't have 12+ — they already denied opening strength.

Drury fills that gap. Together, they cover all responder hand types:

• Non-passed hand with 12+ HCP + new suit → 2/1 game force
• Non-passed hand with 10-11 HCP + support → 1NT forcing, then show support
• Passed hand with 10-12 HCP + support → Drury (2♣ or 2♦)
• Passed hand with 6-9 HCP + support → Simple raise or jump raise (preemptive)

The convention was invented by Douglas Drury, a San Francisco bridge player, in the early 1960s. It quickly became standard among 5-card major players because of how cleanly it solves the passed-hand limit raise problem.
