raising partner in competitive auctions

[dfm]

In competitive auctions, I play that responder's cue bid of an overcall is a limit raise or better, and a jump raise is preemptive. For example:

1H (1S) 2S = limit+ raise
1H (1S) 3H = preemptive

Similarly, I play that advancer's cue bid of opener's suit is a limit raise or better, and a jump raise is preemptive.

(1H) 1S (Pass) 2H = limit+ raise
(1H) 1S (Pass) 3S = preemptive

Is it standard to have the same agreement for opener's rebid in a competitive auction? For example:

1D (Pass) 1S (2H) 3H = limit+ raise
1D (Pass) 1S (2H) 3S = preemptive

If so, what should opener's hand look like for a preemptive raise?
If not, then what should these bids mean?

No, opener has announced a non-preemptive hand, so there are no preemptive rebids by opener. Opener can have extras in the form of high cards or distribution or both, and sometimes there are options to portray these differences. Also, opener has fewer forcing bids available than does responder -- after a 1 over 1 sequence, opener must generally reverse or jump shift to force, or make a splinter or other conventional raise.

Your first auction, cue-bidding the enemy suit, is usually played as a general game force. Often opener will have a strong, balanced hand lacking a stopper in hearts, and would welcome 3NT from partner. Or, opener has a hand too strong to rebid 3D, but does not want to pass up 3NT. Or, opener has a very powerful hand in support of spades, which will be obvious if 3NT is pulled to 4S. The second auction is game invitational, worth approximately 17-19 points in support of spades; the extra values could be high cards or distribution, usually some of both. A hand worth 20-22 would raise directly to 4S while 23+ would go through the cue-bid first. ("23" typically means about 20 hcp with four trumps and a singleton.)

IMO 3S is a 6 loser hand with 4 card support but relatively minimum
points whereas 3H shows the same 6 losers (could be better however) but
also a good hand in HCP's, say 15+.

If not sure then try 3H with aces and kings but 3S with Kings and queens.

Similarly 4S should be 5 losers with mainly kings+queends but go via 3H
if 5 losers with aces and kings.

I like no negative double when both majors have been shown.

1H (1S) 2S = 4+cards in hearts limit+ raise
1H (1S) X = likely to be 3 card limit+ raise.
1H (1S) 3H = preemptive
1H (1S) 3m = 9+ cards in minor + spades limit raise+. Jump fit in contested auctions. If responder is a passed hand, only forcing back to 3H.

Far too much material for one thread. In a book each topic would be entitled to its own chapter.
