Dumped inverted minor raises long ago and have never regretted it. I've lost count of the number of times the other table has gone down in a silly 1NT from the wrong side while we were getting a plus score. Being one step higher on the good hands is immaterial because there is plenty of space.

What's your approach to hands that would normally make an inverted raise? I've played IM for long enough that I don't really know alternatives for creating forcing auctions in those situations. Would like to hear more.

(Somewhere I read an article by Matt Granovetter about a client who insisted on some insanely complicated system that nonetheless didn't have any way to show support for a minor with a strong hand, as he realized on an early deal when partner opened 1D opposite his 2362 17-count.)

In one partnership we dropped Smolen and haven't regretted it.

After a deep discussion in the bar one of our pairs decided to play reverse Smolen and alert it as such.

In my case I've played 1nt - 3 of a suit as everything from 5-5 weak/strong in the minors and 5-5 invite strong majors, natural invite... you name it. None of them come up or would have and get dumped on a regular basis.

Currently playing 3 of a major as 1-3 - (45 or 54) hoping it will be the good imp swing (that never happens).

Five card majors, short club, forcing no trump, 2/1 game force, Drury, weak jump shifts

Having a 2NT on your convention call as "unusual" does not mean you have to bid 2NT everytime you hold 5-5 in the minors. It just means when you make that bid, it is what you are supposed to hold.

A lot of these "butt-in" conventions can help place the cards if you lose the auction. It can also sometimes lead to the opponents making correct bidding decisions, e.g. play in NT rather than a major if they are likely to suffer ruffs and bad breaks.

Many players use Criss-Cross: 1♣-2♦ and 1♦-3♣ are good raises.

Yeah, I can't remember the last time one of my 3-level responses came up (except using 3♣ as a transfer to ♦). And I've come up with a Murphy's Law of Bridge: if you discuss whether to use one convention or another, whichever you choose, the other type of hand will come up in that session.

Criss-Cross is simple.

1♣ 2♦ can be used very effectively as there is lots of room to explore. 1♦ 3♣ not so much.

My preferred method is:

1. Fit jumps into the majors 1m 2M 10+ 4+m 4+M

2. 1m 2NT GF raise no shortage

3. Splinters at the three level

I couldn't find FILM doing a Google search. What is it? How does it work? Or better, do you know of a link to it?

Gerber, Rolling Gerber, Roman Gerber, modified Gerber (the latter using 4NT as the king ask)

I daresay I could fill a couple of pages if I thought of every little thing.

Gerber we all know. What exactly are the other three?

There were two gadgets that Shogi and I replaced with more natural methods, though. One was to get rid of G/B 2NT. The other was to replace Multi-Landy with Landy.

Very interesting this. Usually it is done the other way round i.e. replacing Landy with Multi-Landy.

Definitely use 2♦ over 1♣. Being one step higher doesn't cost. You lose whatever you were doing with 2♦ before, which for most people is nothing that matters.

Over 1♦, you can use 2♥. I don't mind losing a weak or intermediate jump shift and 3♣ as the only good raise doesn't leave enough space. You can still use 3♣ to cover some of the hand types though. If playing reverse flannery which I quite like, 2♠ has to be the main way of raising diamonds which is still ok.

Use the edit button rather than triple post. It's bad practice.

FILM is Fishbein Incorporating Lower Minor, a very old-fashioned defence against 3 level preempts. It works like this:

X is penalty
3♣ - 3♦ is takeout
3♠ - 4♣ is takeout
3♦ - 4♣ is takeout denying 4 hearts
3♥ - 4♣ is takeout denying 4 spades
3♦ - 3♥ is takeout with 4+ hearts
3♥ - 3♠ is takeout with 4+ spades
other calls are as in Standard

Rolling Gerber is where the king ask is the next step after the ace response. My first teammates swore by Rolling Gerber. Roman Gerber is where the responses are 0/3, 1/4, 2 same colour, 2 same rank, 2 same shape. This was based on an early attempt to improve simple ace asking (Roman Blackwood) and recommended to me by one of my teachers. Modified Gerber was using 4NT as the king ask, the theory being that you only used Gerber with an unbalanced hand with clear direction, so you never wanted to stop in 4NT.

Note I am not recommending any of these conventions.

[GreenMan]

Thanks all for the alternatives to inverted m's. Food for thought.

[blackshoe]

Hugh Kelsey wrote Slam Bidding in 1973. The book included several variants on Blackwood, including Norman Blackwood, which I don't remember at all, and my favorite, Byzantine Blackwood, which truly was Byzantine. So much so that I never even tried to play it.

No idea, the policy predates my tenure here. Maybe someone responsible for the decision will answer in the other thread you asked this in.

Yes to this. 2♦ for the forcing ♣ raise, and 2♠ for the forcing ♦ raise. I can't imagine wanting to play without a simple raise available (1♣-2♣ and 1♦-2♦). You win as mentioned on the hands where you don't have to wildly distort your 8 cts into LR+ or preemptive or wildly offshape/misdirected 1nt, and you win even more when your simple raise allows partner to compete effectively to 3m or 4m, where at other tables they never establish they have a fit -- or they establish it only after opps have gotten in. My partners and I have had numerous 1♦(p) 2♦ (p) 3♦ all pass auctions, where they can't have those with IM. Your preempts now become preemptive, and not just whatever 6-8 count you had to round down. Etc... For all strains, you need a simple raise, a forcing raise, and a preemptive raise available, at least as is possible.

IM is one of the conventions I simply won't play unless partnering a newcomer.

IMO how useful inverted minors are depends on the rest of the system. We play a weak no trump (so 1m has extra shape or extra values) and all suit openers minimum 4 cards, and find inverted minors are great. I can see that if you play a 2+ card club, you might not want to go nuts with 5 opposite, but we know we're facing a 15 count or 5 clubs unless exactly 4414, so bid 2N/3♣. We put a lot of hands through the inv minors, they are not GF and may contain a 4 card major so auctions like 1♣-1♥-1♠-2♦-2♥-3♣ are known to be exactly 3 card support as with 4-4 we'd have started with the invert.

That said, I only play them with my regular partner, not in pickup partnerships.

In those methods (and I'm a 10-13nt'er too), how do you make a simple raise of the minor? It's not the forcing raise that's at issue; you keep a forcing raise under any sensible methods. But with IM you lose any ability to make a simple raise when you have a simple raise hand.
