Bridge Bidding Cheat Sheet

Everything you need at the table on one page: how to count your hand, what each opening shows, and how to respond — the standard system distilled to its essentials.

Updated June 2026·6-minute read·Reference
The whole system, briefly: Open with 12+ points — a suit, or 1NT with a balanced 15–17. Respond by adding your points to partner’s, supporting a fit or showing a new suit, and aim for game with about 25–26 combined.

The numbers that matter
Three numbers anchor the whole system: about 12 to open, 25–26 for game, and 33 for slam.

Step 1 — Count Your Hand

Value every hand the same way before you do anything else. High-card points are the currency of bidding.

High-Card Points & Targets

A=4 K=3
Q=2, J=1. 40 high-card points in the whole deck.
12+
Open the bidding — or a shapely hand passing the Rule of 20.
25–26
Combined for game — the partnership target.
33 / 37
Small slam / grand slam combined.

Step 2 — Opening Bids

With opening values, pick the bid that best describes your strength and shape. Full detail in opening bids.

Standard Opening Bids

1♣/1♦
12–21, a minor suit. Often the "better minor" with no five-card major.
1♥/1♠
12–21, a five-card major. Bid the longer; with two five-baggers, the higher.
1NT
15–17, balanced. No void or singleton, at most one doubleton.
2NT
20–21, balanced.
2♣
22+ (artificial & forcing). The one strong opening — says nothing about clubs.
2♦/2♥/2♠
Weak two — 6–10, six-card suit. Pre-emptive and disruptive.
3-level
Pre-empt — seven-card suit, weak hand.

Step 3 — Responding to a Suit Opening

When partner opens one of a suit, answer with your points and your support.

Responses to 1 of a Suit

Pass
0–5 points. Too weak to respond.
Raise
6–9 with support — raise partner’s major to the two level.
New suit
6+ points, forcing. Show a four-card-or-longer suit, up the line.
1NT
6–9, no fit or new suit to show at the one level.
Jump raise
Invitational+ with four-card support — agree the trump suit and show extras.

Step 4 — Responding to 1NT

Partner’s range is known, so take charge. The full guide is responding to 1NT.

Responses to a 1NT Opening

2♣
Stayman — asks for a four-card major (need 8+).
2♦/2♥
Transfers — 2♦ shows hearts, 2♥ shows spades (five+).
2NT
Invitational, 8–9 balanced.
3NT
Game, 10–15 balanced.
4NT
Quantitative slam invite, 16–17.

The Key Conventions

Four agreements cover most of what you will meet early on. Add them once the natural bidding above is automatic.

No-Trump Tools

  • Stayman (2♣) — find a 4-4 major fit
  • Transfers (2♦/2♥) — show a five-card major

Slam Tools

Print this page and keep it beside you for your first few sessions. Once the openings and responses feel automatic, you will not need to look — and you will be ready to add the conventions that refine the system.

Key Takeaways

  • Count A=4, K=3, Q=2, J=1; open with 12+, aim for game at 25–26.
  • Open a five-card major, the better minor, or 1NT with 15–17 balanced.
  • Respond by supporting a fit, showing a new suit, or bidding no-trump.
  • Over 1NT use Stayman and transfers to find the right major.
  • Add Blackwood and cue bids only when you are heading for slam.
