PROPOSING a New 4-card suit after a 1-Suit Opening Bid
Yellow Card Bidding System Mantra ● First, determine which suit to play - then determine the contract level to play. ● Try to play a contract in the following priority:
1) Play a MAJOR suit contract.
2) Play a NO TRUMP contract.
3) Play a MINOR suit contract as a last resort.
As soon as the opener makes an opening bid of 1-SUIT, the responder immediately knows the opener's point count range (12 to 21 HCPs) and the minimum number of cards the opener's suit (5 or 3 cards). The ability to propose a new 4-card suit depends upon the responder's point count range:
Point Count Range:
Propose a New 4+card Suit after a 1-Suit Opening
• Keep the proposal bid at the lowest level possible to leave bidding room for the opener to either support or propose another suit.
• In order to propose a new 4+card suit, the new 4+card suit must not be subject to the 1-over-1 restriction.
The 1-over-1 Restriction
"The responder with 6-9 HCPs can only propose a new 4+card suit at the 1-level."
• Always propose a new 4+card suit at the lowest possible level to leave bidding room for the partner.
• Every bid must be made at a higher level of hierarchy than the previous bid. Bids cannot be re-used or go backwards.
• When the responder has only 6 to 9 HCPs, the 1-over-1 restriction is in force and applies a barrier to bidding at the 2-level or higher.
• The responder with 6-9 HCPs can only propose a new 4+card suit at the 1-level
The following describes how the responder proposes a new 4-card suit when holding only 6-9 HCPs (1-over-1 restriction):
Response to 1 ♣ opening bid with 6-9 HCPs.
×
IGNORE the clubs (for the moment), even if the responder has a 5+card club suit to support the opening bid. The SAYC priority is to try for a major suit contract first.
When the opening bid is 1 ♣ and the responder has 6+HCPs, there is no no 1-over-1 restriction. Any new 4+card suit can be proposed at the 1-level.
1) If the responder has a new 4+card major suit, the responder should propose the 4+card major suit at the 1-level, and ignore a 4+card diamond suit. The Yellow Card priority is to explore a major suit contract first. The opener may be holding a 4-card major suit but could not open it. Consequently the responder should propose 1♥ or 1♠ .
2) If the responder does not have 4+card major suit, but does have a 4+card diamond suit, the responder should propose 1♦ .
3) If the responder does not have a 4+card suit to propose and a flat hand (3-3-3-4), the responder must bid 1NT . This flat hand may play better in a not trump contract.
• If none of the three choices above are possible, it means the hand has at least 5+clubs. In this case it is best to support the opener's club suit at the appropriate level.
• The responder must NOT PASS since that would indicate a lower point range hand and provide wrong information to the opener.
IGNORE the diamonds and clubs (for the moment), even if the responder has a 5+card diamond suit to support the opening bid. The SAYC priority is to try for a major suit contract first.
When the opening bid is 1 ♦ and the responder has 6+HCPs, there is only one 1-over-1 restriction - the responder cannot propose clubs.
1) If the responder has a 4+card major suit, the responder should propose that 4+card major suit at the 1-level. The Yellow Card priority is to explore a major suit contract first. The opener may be holding a 4-card major suit but could not open it. Consequently the responder should propose 1♥ or 1♠ .
2) If the responder does not have a 4+card major suit to propose, but does have a 5+card diamond suit, go ahead and support the diamonds at the appropriate level.
3) If the responder does not have a 4+card major suit to propose, and does not have a 5+card diamond suit to support, the responder must bid 1NT . This ARTIFICIAL bid is a point range bridge indicating no 4+card major, and nothing about a club suit.
• The responder must NOT PASS since that would indicate a lower point range hand and provide wrong information to the opener.
When the opening bid is 1 ♥ and the responder cannot support the hearts, the responder with 6-9 HCPs can only propose a new 4+card spade suit. The 1-over-1 restriction prohibits proposing clubs or diamonds.
1) If the responder has a 4+card spade suit, the responder should propose 1♠ 2) If the responder has 6-9 HCPs and no major suit support, the responder must bid 1 NT . This ARTIFICIAL bid indicates 6-9 HCPs with NO major suit support. It says nothing about clubs or diamonds, and is not a desire to play a No Trump contract.
• The responder must NOT PASS since that would indicate a lower point range hand and provide wrong information to the opener.
When the opening bid is 1 ♠ and the responder cannot support the spades, the responder with 6-9 HCPs can not propose another 4+card suit. The 1-over-1 restriction prohibits proposing clubs, diamonds or hearts.
The responder must bid 1 NT . This ARTIFICIAL bid indicates 6-9 HCPs and no spade support. It says nothing about the other three suit, and is not a desire to play a No Trump contract.
The responder must NOT PASS since that would indicate a lower point count hand and provide wrong information to the opener.
The responder must NOT PASS
The selection of the appropriate response bid depends upon the opened suit, the strength of the responder's hand and the Yellow Card priorities. For more information on the appropriate response bid, go to one of the following four web pages:
