Understanding the Game Force and When to Use 2/1 Bids

• Download the Worksheet

At the heart of the 2/1 system is the idea that a new suit bid at the two-level by responder after a one-level opening by partner creates an immediate game force. This means neither partner can pass until a game contract is reached.

For example, if your partner opens 1♥ and you hold 14 points with three hearts, you know you have a game and a fit in hearts. But if you think you might have enough for a slam, you would respond 2♣ to set the game force and explore further.

Conversely, if your partner opens 1♠ and you have 14 points but only four spades, you don’t yet have a fit for spades. You might respond 2♣ or 2♦ to create the game force and clarify the best contract as the bidding proceeds.

Key Characteristics of a 2/1 Auction

• Partner opens one of a suit (usually a major).
• Responder bids a new suit at the two-level (not a jump).
• This bid creates a game force — the partnership must reach at least game.
• Responder must hold an opening hand of at least 13 points.
• 
  

Marla lists the valid 2/1 sequences as:

• 1♥ – 2♣
• 1♥ – 2♦
• 1♠ – 2♣
• 1♠ – 2♦
• 1♠ – 2♥
• 1♦ – 2♣

These sequences are the only ones that qualify as 2/1 game forcing bids. Bids that are jumps, no trump, or occur after interference from opponents do not count as 2/1 bids.

Choosing Which Suit to Bid at Two-Level

One common question Marla answers is how to decide between bidding 2♣ or 2♦ in a 2/1 auction. The general guidance is:

• Choose your better suit, especially if one is four cards and the other three.
• If both suits are four cards, choose the stronger suit or the higher-ranking suit depending on hand shape.
• For the special case of 1♠ opening, a 2♥ response must be a five-card heart suit (not a jump), fulfilling the 2/1 game force.

Marla stresses that you don’t always have to have a genuine long suit for the 2/1 bid. It primarily establishes the game force and says, “Partner, don’t stop bidding until we reach game.”

When 2/1 Does Not Apply

Marla clarifies several situations where 2/1 bids are not applicable:

• If responder was a passed hand (passed earlier in the auction), they lack the strength to force game.
• If opponents have intervened with a double or bid, 2/1 is off.
• If the two-level bid is a jump, it is not a 2/1 bid.
• If the bid is in no trump, it is not a 2/1 bid.

For example, pass – pass – 1♠ – pass – 2♣ is not a 2/1 auction because responder initially passed.

The Role of Opener’s Second Bid After a 2/1 Response

Once responder makes a 2/1 game forcing bid, opener’s job on the next call is to show their hand shape naturally. This means:

• If opener has a second suit with at least four cards, they should bid it, especially if it’s a major suit.
• If opener has six or more cards in their original suit, they may rebid it.
• If opener’s hand is balanced, they should bid 2NT.
• Opener may also raise responder’s suit if they have support.

There is a special exception when opener starts with 1♦ and responder bids 2♣ (a 2/1 auction). If opener holds five diamonds, they should rebid 2♦ even without six cards, to show their shape clearly and quickly.
