1NT Forcing

Updated March 2026 with the latest strategies and examples.

In 2/1 Game Forcing, a 1NT response to partner’s major-suit opening is forcing for one round. Opener must bid again, allowing the auction to develop further.

Why Forcing?

In 2/1, a two-level response is game-forcing (13+ HCP). But what about hands with 6-12 points? You need somewhere to put them.

The solution: 1NT is forcing, covering a wide range of hands that aren’t strong enough for 2/1.

What 1NT Forcing Shows

After 1♥ or 1♠:

Response Meaning

1NT 6-12 HCP, forcing one round

2♣/♦ 13+ HCP, game-forcing

The 1NT bid is a “catch-all” that includes: - Balanced hands without a fit - Hands with support but not enough for a limit raise - Hands with a long minor but not enough for 2/1

Opener’s Rebids

After 1♠ - 1NT (forcing):

Rebid Meaning

2♣ 3+ clubs, any strength

2♦ 4+ diamonds, any strength

2♥ 4+ hearts

2♠ 6+ spades, minimum

2NT 18-19 balanced

3♠ 6+ spades, extras

Opener MUST bid - passing 1NT forcing is not allowed.

Example: Responder’s Hand

You hold: ♠74 ♥K83 ♦QJ74 ♣J962

Partner opens 1♠.

• 2♦? No - that’s game-forcing in 2/1

• 1NT? Yes - 8 HCP, forcing, lets you hear more

After 1♠ - 1NT - 2♥, you can raise to 3♥ (invitational) with your heart support.

Responder’s Second Bid

After 1♠ - 1NT - 2♣:

Rebid Meaning

2♦ Natural, non-forcing

2♥ Natural, non-forcing

2♠ 2-card support, minimum

2NT 10-12, balanced, no fit

3♣ Club support, invitational

3♠ 3-card support, invitational

Semi-Forcing Alternative

Some pairs play 1NT as “semi-forcing” - opener CAN pass with a balanced minimum:

Method Opener Can Pass?

Forcing 1NT No, must bid

Semi-Forcing 1NT Yes, with balanced minimum

Semi-forcing gives opener more flexibility but makes responder’s life harder.

With Support

With 3-card major support and 6-10 HCP, you have options: - Simple raise: Shows 3-card support directly - 1NT forcing: Hides the fit, explores

Many players bid 1NT first with exactly 3-card support and only raise with 4+.
