What are Inverted Minors?
Inverted Minors change the usual minor-raise ladder. The raise to two of opener's minor becomes the constructive route, while the jump to three of the minor becomes the weak pressure bid.
That trade makes sense because good minor raises often need space to look for 3NT, five of the minor, or slam. Weak minor raises usually benefit more from taking away the opponents' room.
Strong single raise
- 2 is not a weak raise in inverted-minor methods.
- Responder starts a constructive diamond auction and keeps opener from passing immediately.
Weak jump raise
- 3 is weak and preemptive in inverted-minor methods.
- Responder usually has club length but not invitational strength.
Responder requirements
The single raise should be a real fit bid, not just a convenient waiting action. A common baseline is about 10 or more points and forcing for at least one round, although partnerships may include slightly lighter constructive hands. Many pairs also use it to deny an unbid four-card major so major games are not lost.
In the strict treatment where the weak jump is limited to roughly 0-6 points, hands of about 7 to 9 points with support are too strong for the jump but too weak for the strong raise. Those hands commonly start with 1NT, even with unbalanced shape. A broad weak jump covering all hands below about 10, or a mixed jump of roughly 7-9, removes that particular gap but changes where the weakest raises belong.
- Single raise: commonly about 10+ points and forcing for one round.
- Jump raise: weak and space-taking in traditional methods, usually with five-card or longer support; the exact range depends on whether the partnership uses a strict, broad, or mixed treatment.
- A common treatment requires five-card club support after a 1 opening and four-card diamond support after a 1 opening. Stricter partnerships may require five diamonds when 1 can routinely be as short as three cards.
- Many pairs deny a four-card major with the strong minor raise.
Opener continuations
After the constructive raise, opener should help decide whether the partnership belongs in notrump, a minor part-score, a minor game, or a slam try.
- New suit at the two level: commonly a stopper or a natural feature for notrump purposes, and forcing. Agree which.
- Two notrump and three of the minor: commonly minimum-range bids, and in limit-plus structures either may be passed.
- Jumps and later bids: usually show extra strength or shape by agreement.
Opener shows a major stopper
- Some partnerships use side-suit bids to show stoppers for notrump.
- Others use side-suit bids as natural features or shape. Define the structure.
Opener bids notrump
- 2NT commonly shows a balanced minimum with stoppers in the unbid suits, although some pairs assign it a different range.
- Responder can pass, raise, or continue toward minor-suit game or slam depending on agreement.
Opener signs off with a minimum
- In many structures 3 shows a minimum unsuitable for notrump.
- In limit-plus methods responder may pass with a minimum strong raise; game-forcing pairs keep bidding.
On and off rules
Inverted Minors need clear competitive rules. Some pairs play the convention on after a double but off after an overcall. Others use different structures once the opponents enter the auction.
- Decide whether 1m - double - 2m is still inverted.
- Decide whether 1m - overcall - 2m is natural, competitive, or a cuebid-style raise.
- Decide whether inverted raises apply by a passed hand. Many pairs keep the structure but treat the single raise as a limit raise that opener may pass.
- Decide whether the strong raise is forcing to game or only one round.
Hand examples
Inverted Minors work best when the strong raise is constructive and the weak raise is genuinely preemptive.
Strong diamond raise
- After partner opens 1, responder has diamond support and invitational-plus strength.
- Use the single raise if the partnership plays inverted minors and no four-card major is being bypassed.
Weak club raise
- After partner opens 1, responder has long clubs but not constructive strength.
- The inverted jump raise to 3 describes the preemptive hand immediately.
The in-between hand
- After partner opens 1, 8 points is too much for the weak jump and not enough for the strong raise.
- In a strict 0-6 jump-raise treatment, responder commonly starts with 1NT; pairs playing a mixed or broader jump raise can bid 3 instead.
Common mistakes
- Forgetting that the single minor raise is the strong raise.
- Using inverted minors with an unbid four-card major without agreement.
- Failing to define whether the convention is on after a double or overcall.
- Treating opener's side-suit bids as stoppers when partner thinks they are natural.
- Stretching in-between hands of about 7 to 9 points into either raise when the partnership plays the strict 0-6 jump treatment.
FAQ
Does 1 - 2 show a weak raise when playing Inverted Minors?
No. In inverted-minor methods, the single raise is the stronger raise and is at least forcing for one round.
Is 1 - 3 weak in Inverted Minors?
Yes, the jump raise is commonly weak and preemptive, but exact strength and suit length are partnership agreements.
