The result is fine, not complaining, but the bidding is just plain awful.

Pass of 3C? WTF ?
Surely 3D after 3C is the better call from its standpoint.

So, South didn't hear it when North said "2NT to play" :ph34r:

I'd kind of prefer if North was considered too strong to use Lebensohl. Direct 3d should be some approximation of 8-11 IMO.

Hi


This is a border hand in the invitational situation.
When doubler only has 12-18 TPs, after lebensohl 2nt, doubler must complete transfer to 3, however 12-18 TPs is too wide range, north only has 9hcp and 8TPs, so passing also is a acceptable option.

I know you disagree with me, np. Now let's assume if you only hold 13hcp, you are sure to make same takeout, after you bid 3 - transfer completed, if north rebids 3nt, I believe you must post this hand and complain about worse bidding.

Any idea?

Hi Stephen Tu

What you said is correct, but this is just your wishful thinking , there are some serious issues in fact.
Now I would replay it with responding 3.



3 says " 4+,10-13 TPs". Here it is very difficult to understand why south pass.
Here it is seems Gibs don't know how to bid next, but I am surprised to find Gib CC is no problem.


Result : 3ntN=

Note Gib don't know responding 3, it is my bid.
