opener 1NT rebid with singleton.

[benlessard]

Im wondering about the results for

 

1C-1S-1NT vs

 

1D-1S-2C or 1C-1S-2C.

 

It seem it would be easy to check this on a database.

 

I dont systematically rebid 1NT with a stiff I do it only when my minors are poor. Its not because I know whats best its simply because i didnt feel I had a lot of troubles after 1D-1S-2C.

I don't have the functionality to do it on my database, but maybe soon.

No database here, but I've been opening 1NT on 4441s with strong singleton (AKQ) on a regular basis for a long time. I can't remember any disaster.

I will relate to you my experience with this.

 

For many years, if I held a 5 card major suit as responder, and the auction began 1m - 1M - 1NT, I would rebid my major suit. This usually resulted in playing 2 of a major in a 5-2 or 5-3 fit, and was often better than 1NT. Partner never had a singleton in my major suit, and would have 3 card support often enough that it would be a mistake to pass 1NT. And many times the 5-2 fits played better than 1NT.

 

However, there is more of a tendency today to raise responder's major suit response on 3 card support and there is more of a tendency today to rebid 1NT with a singleton in responder's major. These factors have led to me changing my style so that now I pass the 1NT rebid almost all of the time when I hold a 5 card major (exception - a hand with something like KQJTx of the major with nothing outside).

 

I don't know if I should be alerting this. So far, I consider it to be just bridge. Perhaps others have an opinion on this.

This has continued to be our position because we still don't rebid 1NT with a singleton, and won't raise the Major with 3 when balanced. Our opinion of the results is positive.

Good point, I feel rebidding 2M on 5 is good at MP but im not sure its working in imps. It mean that we must also check 1m-1M-1Nt-2M vs 1m-1M-1NT.

 

I dont really know if more and more offshapes hands (like 2236 or 2254) favor 1NT or 2M. The 5-2 become way more frequent than a 5-3 but its a 5-2 with ruffing potential.
