Standard American Yellow Card
The Standard American Yellow Card (SAYC) is the bidding system the ACBL published so that strangers could sit down and play together: five-card majors, a 15 to 17 point 1NT, a strong artificial 2♣ opening, weak two bids and a short list of conventions.
Updated 13 October 2026
The ACBL wrote SAYC, the Standard American Yellow Card, as the required system for Standard Yellow Card events. It has since become the common language of two players who have never met. In North America it is usually the default for online pickup partnerships, and it is the starting point for most club players learning standard American bridge bidding. The card is deliberately simple, with natural bids, a short list of conventions and no gadgets that need long discussion. This page covers the whole card, one section at a time.
SAYC opening bids
One-level openings show about 12 or 13 to 21 points. Majors promise five cards in every seat. With two five-card or six-card suits, open the higher-ranking. Between the minors, open 1♦ with 4-4 and 1♣ with 3-3.
| Opening | Shows |
|---|---|
| 1♣ | 3+ clubs, 12-21 points |
| 1♦ | 4+ diamonds, 12-21 (three only with 4-4-3-2 and two clubs) |
| 1♥ / 1♠ | 5+ cards, 12-21 |
| 1NT | 15-17, balanced (may hold a five-card suit) |
| 2♣ | Strong and artificial: 22+ or the playing strength of game |
| 2♦ / 2♥ / 2♠ | Weak two: six-card suit, 5-11 points |
| 2NT | 20-21, balanced |
| 3NT | 25-27, balanced |
| 3 and 4 of a suit | Preemptive, usually a seven-card or longer suit |
Balanced hands are shown by range: 12 to 14 opens one of a suit and rebids 1NT, 15 to 17 opens 1NT, 18 to 19 opens one of a suit and jumps to 2NT, 20 to 21 opens 2NT, 22 to 24 opens 2♣ and rebids 2NT. If you are unsure whether to open a shapely 11 or 12 count, the rule of 20 is the usual guide.
Notrump bidding
Over 2NT the same structure moves up a level: 3♣ is Stayman, 3♦ and 3♥ are transfers, and 4♣ is Gerber. If the opponents double 1NT, all these conventions stay on. If they overcall, the conventions are off. Bids become natural, a cuebid of their suit replaces Stayman, and double is negative or penalty by agreement.
Responding to one of a suit
| Response | Meaning |
|---|---|
| Raise to 2 | 6-10 dummy points, 3+ trumps |
| 1NT | 6-10, not forcing, no fit and nothing better to bid |
| New suit at the one level | 6+, 4+ cards, forcing one round |
| New suit at the two level | 10+, forcing one round (not to game) |
| 2NT | Jacoby 2NT: game-forcing raise, 4+ trumps |
| Raise to 3 | Limit raise, 10-11 dummy points |
| 3NT | 15-17, balanced, two-card support |
| Raise to 4 | Preemptive: five trumps, a singleton or void, under 10 points |
| Jump shift | Strong, slam interest |
Over a minor opening, responder bids four-card suits up the line at the one level. 1NT shows 6 to 10 without a four-card major, 2NT shows 13 to 15 and forces to game, and 3NT shows 16 to 18. A single raise of the minor is 6 to 10 and a jump raise is a limit raise. SAYC does not use inverted minors. After the opponents overcall, responder uses the negative double, which applies through 2♠.
Opener's rebids
Opener's second bid shows which of three ranges the hand falls in. The ranges are counted in total points, including distribution once a fit is found.
| Range | Points | Typical rebids |
|---|---|---|
| Minimum | 13-15 | 1NT, a simple raise, rebid own suit, new suit at a lower level |
| Medium | 16-18 | Jump raise, jump rebid of own suit, a reverse |
| Maximum | 19-21 | Jump to 2NT (18-19 balanced), jump shift, jump to game |
A new suit by responder is forcing for one round, so opener with a minimum still bids again. A reverse shows a medium or better hand and forces one round. When responder has limited the hand with a raise or 1NT, opener is the captain and can pass, invite or bid game.
Strong 2♣, weak twos and competition
After 2♣, responder bids 2♦ as a waiting bid with most hands. A positive response shows 8 or more points. A five-card suit is bid naturally, and 2NT shows a balanced 8. Opener's 2NT rebid after 2♦ shows 22 to 24 balanced, and the same Stayman and transfer structure applies.
Over a weak two, a new suit is forcing for one round, a raise is to play and may be preemptive, and 2NT is the only strong inquiry. Opener rebids the suit with a minimum. Holding a maximum, opener shows a feature (an ace or king) in a side suit, or bids 3NT when there is no feature.
| Call | Meaning |
|---|---|
| Simple overcall | 8-16 points, usually a five-card suit |
| 1NT overcall | 15-18, balanced, a stopper in their suit |
| Jump overcall | Preemptive, like a weak two or a three-level opening |
| Cuebid of their suit | Michaels: 5-5 two-suiter |
| Jump to 2NT | Unusual 2NT: 5-5 in the two lowest unbid suits |
| Double of a suit opening | Takeout through 4♦, penalty from 4♥ up |
| Redouble after their takeout double | 10+ points, usually no fit |
Slam bidding uses Blackwood 4NT with simple ace responses, 5NT for kings, and Gerber over notrump. Leads are fourth best from long suits and top of touching honors; signals are standard, with high encouraging and high-low showing an even number.
A SAYC auction
The biggest difference between SAYC and two over one is that a two-level new-suit response in SAYC promises 10 points and forces one round only, while in 2/1 it forces to game. That single change brings the forcing 1NT response and a different style of slow, descriptive bidding. Many partnerships learn SAYC first and add 2/1 later.
