When the opponents leave us to our own devices our NT response structure has all sorts of tools to sign off, invite game and force to game. When they overcall, they make a big dent in what is possible. Lebensohl was invented as a way to recreate some of the space that our opponents have taken away from us. Transfer lebensohl is almost universally played among expert players as it is better than lebensohl in every way possible and is not much more complicated.
