I can only ever remember playing against Ghestem once (about 5 years ago). The Michaels/Unusual 2NT combination is what is inevitably encountered at the table.

What do others think of this convention? Is it good or not?

Pretty much sums it up I reckon.

Can I nominate this topic as "most amusing combination of title and poster" for the annual awards?

Good convention, played by all the top Italian pairs.

Standard in France... if you grow up with it you get confused later when the ACBL bridge bulletin has bidding contests where you hold AKxxx x xx AQxxx, the auction starts (1S)-2S-(P), and everybody tries to guess what is happening :-) (not that this wouldn't be a legitimate problem even with Ghestem in the picture of course).

Another plug for my solution to this since Cthulhu was very kind in recently posting the link in. Ghestem itself is famous most of all for causing TD headaches. It is fine if you are someone who never forgets any system but for the vast majority of players it is simply a bad idea to play it. Arguably, you could also improve Ghestem by moving around the bids a little. For example, Ghestem over 1♦ is

2♦ = spades and clubs
2NT = hearts and clubs
3♣ = hearts and spades

Surely it has to be better to play

2♦ = hearts and spades
2NT = hearts and clubs
3♣ = spades and clubs, weak
3♦ = spades and clubs, strong

giving you back your Michaels cue bid for the majors? Or even RCO

2♦ = hearts and spades
2NT = spades and clubs
3♣ = hearts and clubs, weak
3♦ = hearts and clubs, strong


If a partner insisted on Ghestem then sure, I might play it as a compromise. But I would never choose to play it and there are alternatives out there that are (imho) simply better.

Ok, so we have a mixed audience at to whether or not Ghestem is a good convention. Now let’s throw Questem into the mix.

At the bottom of the above article there is another link comparing UNT/Michaels, Ghestem and Questem.

The author of the article favours Questem. Is (s)he right?

[bluecalm]

Either Ghestem or top/bottom cuebids are superior to michaels imo. You don't really gain much in bidding by showing 5-5 without specific 2nd suit but you give away a lot if they end up declaring.

Is this not the fancy name for one of the methods I mentioned in my post? The loss of the strong hand type in 3♣ is not really an issue at all - you can simply use the jump cue for this.

Ah, but how many times in the past five years have you played against supposed Ghestem where they got it wrong?

The forgets and related director calls are funny and surely true, but let's suppose you can remember the methods.

Ghestem definitely wins on hands where opponents raise the bidding and advancer has a good fit for overcaller's 2nd suit. This certainly comes up and its not hard to give examples. However Ghestem is still a bad method.

1. Frequency. Surely a specific 5-5 shown by 3C is less frequent than a long club suit. The exact same issue (failure to sacrifice or even make when advance fits overcaller's suit) can arise if you are forced to pass the club one-suiter.

2. Effectiveness. When there is no fit, forcing to the three level is much more dangerous; Michaels often can stop in 2M. Telling the opponents both suits can help them in both bidding and play. If 3c is forcing (as in original Ghestem) you give them two cues; if not (as in some mods) you reduce frequency further because you can't use the method on very strong hands in case partner passes.

These are very interesting comments from both of you.

When I encountered Ghestem at the table for the first time, after receiving the explanation from the opponents as to what the bid promised, my then F2F partner and I decided we would experiment with it. We dropped it again about six months later for the very reasons that you mention here:
1. We screwed up the bidding the first two times we had an opportunity to use Ghestem.
2. When we started getting it right, the loss of the 3♣ pre-empt over the opponents opening bid hampered effective interference in the auction.

We subsequently resorted back to Michaels which is what I still play with my current F2F partner.

Feedback from everyone much appreciated. Thanks to all.

I admit to some fondness for Hardy's approach in Competitive Bidding with Two Suited Hands: Top and Bottom Cue Bids, ELC doubles, Unusual NT and a couple of artificial jumps over minor openings (specifically (1♣)-2♦ shows diamonds and hearts, usually 4=5, and similarly (1♦)-2♥ shows clubs and hearts. OTOH, I don't have enough experience with it to know whether it's a better method than standard Michaels. Hardy certainly seemed to think so (yes, I know some here don't think much of Hardy's opinions on bidding theory).

Yes, but some hands with long clubs could be overcalled with 2C and effectiveness of preempt once they open 1M is small (usually they get to their contract anyway and declaring is now much easier). I think this is a good point and surely cost of Ghestem but it's not big.

It's also more preemptive, not much and it doesn't matter that much but it is.

Yeah, but you can just as well overcall 1S instead of using Michaels, this way you are on 1 level and you didn't give them free information which benefits them every time and your side only if partner has 4-4 fits in minors (and this is what we should compare Ghestem to).

My point is that while it's possible that the costs mentioned by you are too much ot make Ghestem > Michaels we have top-bottom cuebid which just dominates Michaels in every area.

I think there is a good point here, that we should differentiate between times when they open 1m and 1M. This is one of the reasons why my proposed method (the one where the cue is a wjo in a major or top+bottom strong) only applies to a 1m opening. The gains of playing this kind of thing diminish when they open 1M.

The main benefit of playing Michaels for these hands is (arguably) to get them out of other auctions. If you play top+bottom plus ELC you are affecting your auctions after a double. If instead you overcall 1♠ then you either lose the inference that a 1♠ overcall followed by a new suit shows a good hand or you simply give up on those hands. This is even worse when they open spades and we have hearts - do we really think it is a good idea to throw weakish ♥ + minor 2-suiters into a 2♥ overcall?

In this respect I think it is misleading to say that the only gains from Michaels are when partner has 4-4 in the minors. It is certainly reasonable to suggest that the losses from ELC are less than the losses of the minor being unknown in the cue bid. I have not seen any statistics but enough good players have switched to using ELC that it would be difficult to escape that conclusion. On the other hand there are still plenty of good pairs using Michaels which also suggests that both methods are reasonable.

Michaels is a reasonable method. If it wasn't, it wouldn't be so popular. But that very popularity makes it suspect — how many players (even experts, although less so in their case, I think) play it because "it's standard", or "everybody plays it", or "I've always played it", and not because they've tried all other methods and found them wanting?

There is a second point here - one of the big advantages of Michaels is that it doesn't have much opportunity cost - a natural 2NT overcall and a 'natural' cue are bids you can toss without even noticing. If you want specified two suited over-calls you either need to play some bids multiway which is a large degree of complexity to sort out with partner (after (1C)-2D!-(X) where 2D! was a a pre-empt in an unspecified major, what exactly do your bids mean? It's obvious that 2S should be a paradox advance, but how high does that authorise the 2D bidder to go and what hand types should go?) or sacrifice weak jumps - a relatively common handtype.

Despite the recommendations to play specified two suited bids from Partnership Bidding at Bridge guys, and how helpful knowing what the second suit is in a two suited overcall is to competitive bidding generally, this cost of complexity or oppotunity is, imho, a key reason Michaels remains very popular. It's simple AND effective.

There are at least two other solutions, both of which seem better to me:
- Play only two specific two-suiters.
- Use a jump-cue bid as a two-suiter.
