Lebensohl Over 1NT Interference Jim Berglund’s Bridge Lesson 14 Lebensohl is a convention used to enable a better indication of the strength of the responder. Bids can be weak, invitational, or forcing to game Note the use of colors to show strength In today’s competitive bidding environment, overcalls are made far more frequently. Without long discussion, it is difficult to know what to bid when opponents overcall 1NT – and what partner will understand by whatever action you take.

Lebensohl Over 1NT Interference - Six Basic Concepts to Memorize Jim Berglund’s Bridge Lesson 14 1.Responder’s Doubles & Redoubles over a 2-level bid are penalty-oriented 2.Responder’s Doubles over a 3-level bid are Take- out 3.If Responder bids 2NT, Opener MUST bid 3♣ 4.Responder’s 2-level suit overcalls are to play 5.Responder’s 3-level suit overcalls are forcing 6.If a Responder’s auction does not include 2NT, she denies a stopper.

*typically, a strong, balanced hand Note the difference in the 3 responding doubles

Note That 2NT MUST be used in all invitational and forcing hands with a stopper!
