Basic Lebensohl after 1N opening


After 1N-X you ignore double and play systems on. Can give special meaning for pass and redouble.

After 1N-2♣ you double for Stayman and otherwise ignore bid and play systems on.

After 1N-2♦

-double Penalty opener must pass and cooperate in penalizing if they run

-2♥ sign-off but opener can still "super accept" as if a transfer or compete with good trump

-2♠ sign-off same as over 2♥

-2N puppet, opener must bid 3♣ no matter what they have

      -3♣ forced

             -pass to sign-off in Clubs

             -3♦ Stayman with a ♦ stopper, (cue-bids are Stayman, going slow by bidding 2N means you have a stopper

             -3♥ natural INV

             -3♠ natural INV

            -3N to play with a ♦ stopper (went slow with 2N so have a stopper)

-3♣ natural forcing

-3♦ Stayman without a stopper

-3♥ natural forcing

-3♠ natural forcing

-3N game values but lack ♦ stopper (went fast no 2N) if opener has no ♦ stopper you scramble, may end up in 4♣ or 4-3 major fit

 

works basically the same over 2♥/2♠
