Openers rebid with 7m3M when responder shows the major

[bravejason]

Playing SAYC or similar in an uncontested auction. Opener holds a minimum hand (e.g. 11 or 12 HCP) with a 7 card minor and a 3 card major. After opener bids 1 minor, responder bids the 4 card major for which opener has three card support. For openers rebid, does opener rebid the minor, raise responders major, or do something else? Would it be appropriate for opener to jump rebid the minor?

 

Suppose openers RHO makes a simple overcall or negative double. Would that change openers rebid as compared to the uncontested auction?

When you are that lopsided you definitely want to rebid minor. 7 cd suits can take a lot of tricks. You definitely don't want to play in a 4-3 M fit when you have a 7-1 or 7-2 minor fit; you get forced to ruff and will often not be able to make your long tricks in your minor due to lack of transportation.

 

When you have 6 cd minor only it is a closer decision, more often a coinflip, depends on suit quality, shape, strength.

 

Can jump rebid the minor if you are about an extra ace over minimum.

 

2nd question, depends if you are playing support doubles/redoubles or not to show precisely 3 cd support, and even then you might conceal temporarily the support when very lopsided and feel showing the suit will be more valuable than potentially missing a 5-3 M fit.

There is an old saying: What do you call an 8 card suit?... Trumps. A lot of the time similar feelings should be extended to 7 carders.

This has been helpful. I like the saying about an 8-card suit!

You have the option of a Support X / Support XX, which showes exactly 3 cards.

Raising partners bid, showes a fit, 3 card raises are ok, but he will expect 4 card support,

the interference allowes you to tell him the exact number of cards, you hold in his suit.

The strength of your long suit matters, but the interference gives you an option, and sometimes

you cant make the cheap rebid of your suit due to the interference, but you can make the support

showing bid.

Not standard, but I like a jump to 3N to show this kind of hand. Only if this 7 carder is good though, something like AKJxxxx at a minimum. Basically, with any kind of working fit we have 9 tricks - probably.
