Lebensohl

Quick Summary

Updated March 2026 with the latest strategies and examples.

Lebensohl uses a 2NT relay after interference over partner’s 1NT, distinguishing weak from invitational hands and clarifying whether you have a stopper in the opponent’s suit.

The Problem

Partner opens 1NT, opponent overcalls 2♥:

♠KJ953 ♥74 ♦Q62 ♣842

You want to compete in spades, but is 2♠ weak or constructive?

♠KJ953 ♥74 ♦AQ2 ♣K42

With this better hand, you also want to bid spades. How does partner know the difference?

Lebensohl solves this.

The Basics

After 1NT – (2♥):

Your Bid Meaning

2♠ Constructive (8-9 points)

2NT Relay to 3♣, then pass or bid weakly

3♣/3♦ Invitational (natural)

3♥ Stayman (may or may not have stopper)

3♠ Game-forcing

3NT To play (has heart stopper)

The 2NT Relay

2NT = “Bid 3♣, partner.” Then you clarify:

Weak Hand, Long Suit

♠74 ♥62 ♦QJ9743 ♣842

1NT - (2♥) - 2NT - (Pass) 3♣ - (Pass) - 3♦

Pass 3♣ with clubs, or correct to your suit (weak).

Weak Hand, Clubs

♠74 ♥62 ♦842 ♣QJ9743

1NT - (2♥) - 2NT - (Pass) 3♣ - Pass

You wanted to play 3♣. Done!

Slow vs Fast

The key distinction:

Auction Meaning

1NT-(2♥)-3NT Fast, SHOWS stopper

1NT-(2♥)-2NT-3♣–3NT Slow, DENIES stopper

“Slow shows, fast denies” (regarding the stopper)

Wait, that seems backward? Actually different partnerships play it differently. The most common: – Direct 3NT = Has stopper (fast arrival) – 2NT→3♣→3NT = Denies stopper (slow arrival)

Confirm with partner!

Stayman After Interference

Lebensohl distinguishes Stayman with and without stopper:

Auction Meaning

1NT-(2♥)-3♥ Stayman, may or may not have stopper

1NT-(2♥)-2NT-3♣–3♥ Stayman, DENIES heart stopper

Example Auctions

Weak Hand, Long Spades

♠J97532 ♥74 ♦Q62 ♣42

1NT - (2♥) - 2NT 3♣ - 3♠

Weak spades. Partner passes.

Constructive Spades

♠KJ953 ♥74 ♦Q62 ♣K42

1NT - (2♥) - 2♠

Direct 2♠ = constructive (8-9 points). Partner can raise with fit.

Game-Forcing Spades

♠AQ953 ♥74 ♦AQ2 ♣K42

1NT - (2♥) - 3♠

Direct 3♠ = game-forcing.

When Lebensohl Applies

Lebensohl typically applies: – After partner’s 1NT is overcalled at the 2-level – Sometimes after partner’s takeout double of a weak two

Key Takeaways

2NT = relay to 3♣ — Then pass or bid weakly
Direct suit bids = constructive (not weak)
Jump to 3-level = forcing
Stopper info via slow/fast, Clarify with partner
Complex convention, Requires firm agreement

Frequently Asked Questions

What does “slow shows, fast denies” mean?

Going through 2NT first (slow) shows a stopper in the opponent’s suit. Bidding directly (fast) denies a stopper. This helps partner decide between 3NT and suit contracts.

Do I need Lebensohl to compete after interference?

No. Many pairs simply play that all suit bids are to play and 2NT is natural. Lebensohl adds precision but also complexity. Discuss with partner before adding it.

What if RHO bids 2♣ (natural or artificial)?

Lebensohl works best against natural 2-level overcalls. Against artificial bids like Cappelletti, you might need different agreements. Many pairs use “system on” or double for penalty.

Can responder use Stayman after a 2-level overcall?

With Lebensohl, you can! Bid 2NT first (relay), then 3♣ is Stayman. A direct 3♣ (skipping the relay) is natural and invitational. The slow/fast principle applies here too.

What strength do I need for the different sequences?

Through 2NT then passing 3♣: 0-7 points (weak). Direct 2-level suit bid: about 8-10 (competitive). Through 2NT then bidding: 8-10 (invitational). Direct 3-level: 10+ (game forcing).
