The following arose during a game in the Intermediate/Advanced Club and led to some discussion.
At the table, a natural 2NT was selected. Kibbing, I commented that many would play 2NT as Lebensohl here. It became clear that many play Leb in this situation much as they do after an overcall of 1NT, so fast 3NT denies a stopper, slow shows a stopper. My practice is different. An immediate 3NT is pretty much to play unless doubler has an exceptional hand, and a slow 3NT (2NT as a relay to clubs then 3NT) shows a stopper but some doubt as to whether 3NT is the right choice. Doubler, with a stiff heart and decent minors, should probably pull.
Anyway, this is a multi-part question.
a. Not playing Leb, 2NT sounds right? You have to show your strength somehow.
b. Playing Leb, how do you handle this? The choices are, I assume, 3♦ which shows some values (since 2NT->3♣->3♦ is weak) or else getting to either a fast or slow 3NT. The hand is a bit weak for such a unilateral game bid, is it not? But then you would bid 3♦ if the Ace of clubs were the Queen, right? That woould seem to be about minimum for 3♦?
I'll show the hands later for whatever interest they have, but the given hand seems to me to be a situation that arises uncomfortably often when playing Leb.
