AFTER OPENER REBIDS SAME MINOR

After a minor opening followed by a response in a major and a rebid in
same
minor what are the agreements to continue the bidding by Responder?
In the same way we use New Minor Forcing to ask for 3 cards support in our major or to know more information of opener's hand,
here we need establish the agreements about what is a sign-off, what is a
invitation hand and what is a Game Force (GF) hand after Opener's minor
rebid.
RULE#1:
After Opener bids 1
and rebids 2
Responder's relay in 2
is an antificial bid that promise 10+ hcp and is asking for support of 3
cards in our major bided or more explanation of Opener's hand and strength -
one-round force:
RULE#2: After Opener bids 1
and rebids 2
Responder's relay in 3
it is an
artificial bid that establish Game Force (GF) and asks for support in
our major bided or more explanation
in Opener's hand and strength:
Thus Responder will use two artificial bids for GF auction:
Opener Responde
1
1 major
2
2 <= asking for support, one-round force 10+ hcp
Opener Responder
1
1 major
2
3 <= artificial
bid asking for support GF 12+ hcp

In
these invitation hands Opener could rebid his long 7 cards
suit if he is
singleton or void in Respnder's suits and may
pass with minimum
and 2 cards support; assuming that
Responder has 2 cards
in Clubs to avoid misfit.
Opener Responder

Opener's point of view this hand can be a misfit if he is

WHEN THE MINOR REBID IS IN JUMP OR TO 3NT
Some partnership have special agreement to show opener strong minor:
1- Opener rebids to level 2
Opener Responder
1
1 major
2 <= up to
16 hcp (not good) QJ109xxx
or AQ7xxxx or AQJ87x
Opener Responder
1
1 major
2 <= up to
16 hcp (not good)
KQ98xx or AJ8xxxx
or AK5432
2- Opener rebids to level 3
Opener Responder
1
1 major
3 <= 16-17
hcp (good suit) AKQ109x
or KQJ10xxx
Opener Responder
1
1 major
3 <= 16-17
hcp (good suit)
AKQxxx or
AKJxxxx
3- Opener jump to 3nt
Opener Responder
1
1 major
3nt <= 18-19 hcp (solid suit) AKQJxx
or AKQ7654
Opener Responder
1
1 major
3nt <= 18-18 hcp (solid suit)
AKQJxx or
AKQxxxx
Note: when Opener has doubts betweewn just rebid his minor or jump to
level 3 a good parameter to decide is the suit bided by Responder.
Suppose Responder bids 1
and Opener has x AQx
AKQ109x Jxx
then preventing against an embarrasing rebid of 3
Opener could just rebid 2 ,
but switching Clubs by Spades: jxx AQx
AKQ109x x
now jump to 3 is
much good than just 2 .
The Botton Line
A minor rebids to 3nt shows a solid 6 or 7 cards or at least a good suit
like KQJ10xxx with 18-19 hcp having stoppers in the unbid suits.
