I was West, and partner intended his 2NT as Lebensohl; luckily, he did have a ♥ stopper, and he was able to take 8 tricks when he guessed [C] correctly. But 3♠ is the top spot.
I didn't think Lebensohl should be on when I was a passed hand. He thought that he could use this to distinguish the quality of his ♠: an immediate jump to 3♠ would show 5 (but not good enough for him to overcall on the first round, e.g. Qxxxx), while going through Leb would show the 4 that he actually had.
Is it better for 2NT to be natural or Lebensohl, or something else? Something going through my mind was that if I can balance as light as I did, and partner didn't have enough to make a 2NT overcall, we may be overboard in a natural 2NT, which argues against natural.
