Partner opens 1♦. You have a ♦ fit and enough strength to keep bidding. Reaching for 3♦ feels natural: more points, higher bid. With Inverted Minors, that jump sends the opposite message. The stronger hand raises to 2♦ because it needs room to ask what comes next.
What gets inverted?
The single raise and jump raise exchange jobs. Playing the Bridge Unleashed introductory treatment, 1♦ - 2♦ shows an invitational hand or better and forces opener to bid again. The jump, 1♦ - 3♦, is weak and preemptive. The same idea applies to ♣: 1♣ - 2♣ is the stronger raise; 1♣ - 3♣ is the weak jump.
Those are partnership auctions, with the opponents passing. Once the opponents enter, you need separate agreements. Don't assume that a raise keeps its meaning after an overcall just because it had that meaning without one.
The reason for the switch is practical. A strong hand may need to investigate notrump, find out whether a suit is stopped, or decide whether game is right. Staying at the two level makes those conversations possible. A weak hand has less to investigate and can use the jump to take bidding space away from the opponents.
Look for a major before raising the minor
A minor fit doesn't mean you should stop looking for a major fit. In this treatment, responder bids a four-card major at the one level before making an inverted raise. After 1♦, a hand with four ♠ normally starts with 1♠, even when it also has good ♦ support.
This is an easy habit to lose when you're learning something new. You notice the convention you just studied and reach for it before checking the rest of your hand. Ask about a major first. The minor fit will still be there on the next round.
For a refresher on what an opening and a response promise, start with the bridge bidding basics guide.
A small raise with a real decision behind it
Suppose partner opens 1♦ and you hold:
♠ Q 9 3 ♥ A 8 5 ♦ K J 8 4 ♣ K 10 6
That's 13 high card points, four-card ♦ support and no four-card major. In the workshop treatment, respond 2♦. The low bid doesn't limit you to an invitation. It includes stronger hands too. Partner must make another call, and you can use that information to choose your next one.
Compare that with a genuinely weak hand with long ♦ support and no four-card major. That hand may belong in the jump raise. It isn't asking opener to describe every feature; it's making it harder for the opponents to find their own fit. Agree the support length and weak range with partner. Vulnerability and suit quality still matter.
Forcing one round is different from forcing to game
After 1♦ - 2♦, opener cannot pass. That doesn't mean every later bid is forcing. In Tracey's introductory structure, opener's minimum 2NT or 3♦ rebid can be passed by a responder with only invitational values. A responder with enough for game continues.
That distinction prevents two opposite accidents. One player passes the initial raise because it “sounds like support.” Another drives a minimum partnership to game because “we're playing a forcing convention.” Identify which bid forces and how long the force lasts.
A useful practice question is: after 1♦ - 2♦ - 2NT, which hand are you holding, the invitation or the game-going hand? The auction hasn't changed. Your answer determines whether you stop.
Listen for stoppers, not another fit
In the workshop's ♦ auctions, opener's 2♥ or 2♠ rebid shows a stopper in that major while exploring notrump. It doesn't promise a four-card suit. Responder has already bypassed a four-card major to raise ♦.
A stopper helps you survive the opening lead and develop your tricks. It isn't the same thing as a source of tricks. Before settling in 3NT, think about where nine tricks could come from as well as which suits the opponents can attack. The play-of-the-hand guide connects that bidding decision to the plan at trick one.
Write down the parts that can cause an accident
- How much support and strength do your single and jump raises promise?
- Which rebids can be passed after the single raise?
- How do you show stoppers and choose between notrump and the minor?
- What changes after a double, an overcall or a passed-hand response?
Use your convention card to record the answers. “Inverted Minors” names the starting idea; it doesn't settle every continuation.
Learn it, then play the hands
The Inverted Minors Workshop has a live lesson on September 9, 2026, and Play of the Hand on September 14, both 3 to 5 PM Pacific. One $25 ticket covers both two-hour sessions.
After the sessions, the package includes about 4 to 5 hours of video, a 30 to 50 page workbook, a two-page cheatsheet and PBN practice hands. Watch a decision, try it yourself, then return to the explanation. Use the files in BridgeChamp or another PBN-compatible platform; for BBO, convert them to LIN if its import tool requires that format.
