I've read books that say rebidding shows one more card than the 4 originally promised with a minimum hand; others say it shows 6. What do you play?

When responder bids at the 1-level, a rebid of 2M promises 6. With only 5, you can always bid something else: a new suit, raising responder's suit (raising with only 3-card support is far better than repeating your own 5-card), 1NT, or passing responder's 1NT (if that is not forcing in your methods).

If responder bids at the 2-level, you sometimes have to repeat a five-card, though:
1♠-2♥
2♠*
can for example be 5-5 in spades and a minor and a hand that is too weak to rebid 3m, which would show extra values in most methods.

For responder, rebidding a suit shows 6 if opener's rebid was in a suit

1♣ 1♠ 2♣ 2♠
1♦ 1♥ 1♠ 2♥
1♦ 1♠ 2♣ 2♠

But after a 1NT rebid it can certainly be 5
1♦ 1♥ 1NT 2♥

I may rebid 1NT with a singleton in responder's suit, and I regularly raise with 3, so while I suppose there are exceptions to every rule, I would do my best to look elsewhere for something to do than rebid it on 5.

Hi,

the rebid promises 5 or 6.

At least as many cards as opener showed.
If opener rebids his minor and responder rebids
his mayor, it can be a 5 carder.(*)
It should always deny tolerance for openers long
suit.

(*) But this may depend on partnership style.
If opener raises regular with 3 card support for
responders mayor, the chances, that you catch
opener with tolerance drop, so you should have
a 6 carder.

With kind regards
Marlowe

Bill Root taught in general what 1eyedjack essentially said...: if you have a choice between rebidding an unsupported 5-bagger and "anything else reasonable" then choose the "anything else". If there is no such choice, then you may have to grit your teeth and rebid it.

nb - if opener has reversed (e.g. 1♣ North - 1♠ South - 2♦ North), then people play different methods as responder, but i think almost all play that responder's rebid of his major suit here merely promises 5 pieces, and this is unexceptional... Most play that it can still be a non-minimal hand held by responder. This is somewhat of a special case however.
