The effort expended to overcome the shortfalls of Puppet Stayman is truly amazing. Is the diversity and complexity of the continuation bidding structure (not to mention added memory load) really worth all this effort just to have the luxury of being able to include a 5-card major into your 2NT range?

Why not try something much simpler?
2 = 20+ HCP unbalanced (which would make room for your 5-card major), or 22+ HCP any
2NT = 20-21 HCP denying a 5-card major
The continuation bidding structures could look something like this:
2 = 20+ unbalanced or 22+ any
....2 = Waiting 5-7 HCP
....2 = Double negative 0-4 HCP (because the 2 HCP range has been lowered, you can increase the negative response by 1 HCP)
....Anything else = 8+ HCP according to partnership agreement
After 2 it is easy to show your 5-card major on the 2-level instead of the 3-level.
After the 2 Double Negative, the 2 bidder bids appropriately which can include Pass with a 20 HCP count and a 5-card suit. Unfortunately the strong hand is on table but you are less likely to go down in a 2-level contract than a 3-level contract. With 5, it is easy to correct to 2 over 2.
If you don’t want the strong hand on the table, try this:
2-3 (double negative). This way you are 1 level higher but with the strong hand declaring with a 5-card suit. Anything else other than 2-3 can promise 5+ HCP.
[Bad idea as pointed out by Zalandakh]

With 2NT denying a 5-card major, you get to keep all your old gadgets e.g. Garbage Stayman, Smolen. The reduced memory load is considerable.

Which shortfalls specifically. Can you name me a common hand type that a puppet-based scheme cannot handle which a Staymanic scheme could?

Well my 2 opening is 10-14 and natural; but assuming I was playing a natural system for a moment...

... -3 (double negative).

How do you plan to continue after this? You have to manage all 22+ balanced hands as well as Acol 2s and game-forcing hands in all suits - at the 3 level. Go away and test this for a few hands and then come back and tell us again that it is a good and simple idea. Do you not think that if there were a much simpler and better method that most of the multitude of expert partnerships playing some variation on Puppet would not be using it? The truth is that a well-designed Puppet scheme gives you more options over 2NT. There are minuses too for sure and it is much easier to misuse Puppet than regular Stayman. However, the majority seem to believe that overall the benefits outweigh the detractions. I happen to agree with this but am always open to a better method when I find it. Unfortunately the method above is not.

When is responder allowed to pass 2NT when your 2NT may include a 5-card major and 20-21 HCP?

So you feel that playing 2NT which includes a 5-card major opposite a bust is better than playing 2 or 2 opposite a bust? Those trumps may just become vital. If 2NT makes versus 2M making, it is a push at IMPs. On the other hand, 2M making versus 2NT down 1, the gain is big.

I can understand players using Puppet Stayman if their 2 meaning is something like yours. Natural systems (2/1, SAYC), won’t convince me to include Puppet Stayman.

Remind me again how we are playing 2M after the start 2 - 3, which is the equivalent auction to 2NT - p in your proposed method to which I was referring. You also have a second method with a 2 bust. That is probably better but now you have to jump to 3 just to show a game-forcing hand. Again, play with this a bit before suggesting this is an improvement. Is it really worth crippling your constructive bidding just to avoid playing an extremely simple and easy convention like Puppet?

And just so you know, in my strong club system 1 - 1; 2NT - 3 is indeed a form of Puppet Stayman; similarly for 1 - 1; 1 - 1; 2NT - 3. I also play it after a 1NT opening as well as after 1 - 1; 1NT and 1 - 1; 1 - 1; 1NT. In other words, pretty much whenever I can. This allows all of the other openings to be unbalanced. As I wrote earlier this is actually a major point that you are missing in your analysis. If I could not handle any major hand types using it then I would not. This is the other major aspect of Puppet and I will re-iterate it since I think you missed it the first time around.

I do understand bluecalm's position that the artificial bids are too vulnerable to easy doubles from the opponents. I may not agree but it is a perfectly valid opinion. I do not understand a position which says Puppet is too complicated while throwing extra hand types into the 2 opening is not. Or that it is possible to move hands out of a 2NT opening without it impacting other areas of the system. Or indeed that the analysis you posted has any bearing or weight whatsoever. Indeed I have not seen you address any of the points I raised in my (longest post ever) message, nor those from the other posters that took the time to respond.

The truth is that I have now written several lengthy responses to bidding queries that you have raised, using time that I could have spent doing some of the work I am being paid for. I am starting to reach the conclusion that this effort is probably not worth it. It would be nice if you could prove me wrong in this regard...

Zel

For what its worth, I don’t believe that either of us is going to back down on why we use Puppet Stayman or don’t use Puppet Stayman. On this one we will probably have to agree to disagree.

Responder with a Bust Hand
Probably these are the main reasons why I’m not interested in Puppet Stayman:
1. Playing 2NT with 20-21 HCP and a 5332 holding opposite a bust inevitably plays poorly. Unable to stop the opponents running your 2-card suit gets you a bad result. Higher up this thread I suggested something simpler. OK, so suggesting using 2-3 as a double negative was bad. But what about 2-2 as the double negative? Sure you will get plenty of hands with the strong hand on table playing in 2, but more often than not, it will have better chances than a 2NT 5332 hand.
2. With a 4450 or 4441 hand ( shortness), I lose Garbage Stayman with a bust. I hear you say that this is countered by Exit Stayman.
3. With 4405 or 4414 or 4423 ( shortness), I lose Crawling Stayman as well.

In summary, opposite a bust, opportunities to improve the auction are limited. In a different thread, someone else calculated the % of 2NT auctions going down. An interesting stat forming part of this % would be knowing how many Puppet players were forced to pass 2NT which ended up going down.

Responder with a Game Forcing Hand
1. Obviously with a game forcing response you have more options. Even if you don’t always end up in the ideal final contract (3NT versus 4M), the fact that the contract gets made, masks the overall effectiveness of Puppet Stayman.
2. The Puppet Stayman structures that I am more familiar with, concentrate on the majors. Chris Ryall’s website includes a discussion on some of the problems that others have encountered with PS as well as suggestions how others have overcome these problems. As soon as you have to create additional bids to overcome any problem identified, you are adding to the memory load. Some players are better than others when coping with memory load.
3. Some of these additional bids have to do with “right-siding” the contract.
4. When responder has a minor suit orientated hand, inevitably more bids end up being made allowing the opponents more options for lead directing doubles.
5. The 5-3 major fit is not that important at IMPS. 3NT making 9 tricks versus 4M major making 10 tricks costs 1 IMP. 3NT making 10 tricks versus 4M making 10 tricks is a push. 3NT making versus 4M down 1 is a huge gain. I just don’t believe that PS is worth this risk.
6. Responder with 5+3, the partnership may have a 5-3 or a 5-3 fit. If you play Puppet the 5-3 fit is lost. If you transfer to then the 5-3 fit is lost. You cannot butter your bread on both sides. The odds say that it is better to transfer into the suit. To overcome this, you are again adding additional bids to the memory load.

In closing I have this to say. In my books you are still rated as one of my favourite posters. Your posts are informative and objective, seldom if ever subjective. I place high value on the things you post. But on Puppet Stayman I think we will need to agree to disagree.

Ditto ad infinitum. I fully second Codo's statement here. Whatever you do, don't stop posting.

Exactly the same amount as regular Stayman - in fact less, if the auction goes 2NT 3 3 3NT - they don;t know which 4-card major opener has, whereas 2NT 3 3 3NT tells them explicitly.

But 2NT 3 3 3NT shows that responder has no 4-card major so she would not use regular stayman in the first place.

OTOH, using PS
2NT-3
3-3
3-4
Here opponents won't know if opener has four hearts or not, while after the regular stayman auction
2NT-3
3-3NT
4
they will.

Opps will get the oportunity to double both clubs and hearts, though, if you play PS.
The world would be such a happy place, if only everyone played Acol :) --- TramTicket

:P This is a nice thread. It has convinced me to play 3 as puppet over a 1NT open, and 3 as puppet over a 2NT open (Smolen must be considered the lesser benefit).

What it has not helped me with is the ever vexing problem of investigating a minor suit slam after a 2NT opener when I, the responder, have a good 6 card minor and our partnership has about 30+ HCP. Any ideas?

This thread has received a lot of emotional feedback defending Puppet Stayman, probably from people who use it. All the negatives listed on Chris Ryall's website posed the question, “Is Puppet Stayman really worth the effort?”

Maybe I’m wrong, but these forums are here for less experienced players to learn from the more experienced ones. I am now asking these more experienced players to compile a comprehensive convincing list of advantages “Why anyone should switch to Puppet Stayman?” I will place the first one. Kindly add the rest:

Advantages of playing Puppet Stayman: Over 1NT
1. Can include a 5-card major suit holding within your 1NT range.
2.
3.
4.

Advantages of playing Puppet Stayman: Over 2NT
1. Can include a 5-card major suit holding within your 1NT range
2.
3.
4.

I will be the first to apologise if the list of advantages are enough, therein not requiring a rethink of Puppet Stayman


Really I honestly don't see why I should. You obviously aren't interested in reading what people have to say, because there are four pages of thread explaining many of the advantages and disadvantages in detail. You keep going on, and on, about the fact that the 'only' advantage of playing Puppet stayman is to find a 5-3 fit but it's not. You obviously aren't going to change your mind and, what's more, I honestly don't really care if you do or not. I don't have anything to gain by persuading other people to play methods I like - I don't mind explaining them if people are interested, but I'm not in the business of selling bidding system.

I play a form of puppet in response to a 2NT opening, and I'd continue to play something similar even if I never put a 5-card major into my 2NT opening. The value in playing (effectively) a 3C response as a relay, rather than a 'bid your 4-card major' response, is that you gain a lot of possible sequences in a cramped auction.

Your concern about very weak hands in response to a 2NT opening is misplaced. It's a very rare situation, and sometimes the opponents are cold for game anyway. If you hate the very idea of having to get to 2NT opposite a very weak hand, then play a strong 1C/1D system instead: that's the real solution, not mucking around with 2C auctions that are already difficult to manage.

Hi Frances

Partner and I were playing a very basic version of Puppet Stayman which concentrated on the majors (little effort was made to include minor suit orientated hands from responder).

This thread was started when we started asking “why all this PS fuss?” The times when either of us held a 5332 20-21 HCP hand was seldom. More often than not we ended up playing in a 4-4 major suit fit, or a 5-3 major suit fit with responder holding the 5-card suit not the opener. We got there via Jacoby transfer bids.

So I looked up the frequency of occurrence of typical 20-21 HCP NT hands. This is what I found: The probability of being dealt –
1. 5332 and 20-21 HCP = 0.08% (5-card major, minor 5-card suits excluded)
2. 4432 and 20-21 HCP = 0.08%
3. 4333 and 20-21 HCP = 0.12%
...Total.........................= 0.28%

The probability of being dealt a bust –
1. 4450 and 0-4 HCP = 0.01% Club shortness (losing Garbage Stayman)
2. 4441 and 0-4 HCP = 0.07% Club shortness (losing Garbage Stayman)
3. 4405 and 0-4 HCP = 0.01% Diamond shortness (losing Crawling Stayman)
4. 4414 and 0-4 HCP = 0.07% Diamond shortness (losing Crawling Stayman)
5. 4423 and 0-4 HCP = 0.17% Diamond shortness (losing Crawling Stayman)
...Total.....................= 0.33%
Less benefit of 5332..= (0.08%)
Net benefit/loss.........= 0.25%

Having no mechanism to improve the auction when responder has a bust, we were in a net loss situation.

Seeing the numbers, partner and I decided to dump PS. The majority of the face-to-face bridge we play is match points. The decision to dump PS became even easier when we were getting a top score in 3NT making 10 tricks when the rest of the field were making 10 tricks in a major.

I respect your decision for playing PS. I’m just saying why I dumped it.

The value of Crawling Stayman was demonstrated on board 4 during Final 1_3 in the just completed 2012 White House Juniors. OK, so this sequence took place after a 1NT opening bid, but it could just as easily have occurred after a 2NT opening bid.

Both rooms began with Garbage Stayman. In the Open Room, West continued with Crawling Stayman after a 2 response from opener which won his side 3 IMPs.

Are you serious? Just passing out 1NT goes down 4, possibly 3 tricks. Random results of down 3 versus down 4 in different 4-3 fits. Both 4-3 fits could have gone down 4.

As others have noted, puppet Stayman also has it's version of garbage Stayman but based on a different set of distributions which are more likely than regular garbage Stayman. Since you already thoroughly analyzed puppet Stayman, I'm sure you've already done the math.

Your concern about very weak hands in response to a 2NT opening is misplaced. It's a very rare situation, and sometimes the opponents are cold for game anyway. If you hate the very idea of having to get to 2NT opposite a very weak hand, then play a strong 1C/1D system instead: that's the real solution, not mucking around with 2C auctions that are already difficult to manage.


What makes this Puppet Stayman discussion even more depressing for me is this. At our local club there are only a handful of players who can be considered competent. None of these players have ever heard of PS, never mind actually playing it. Yet even these players have managed to work out their own methods of dealing with a big 5332 or similar hand. How have they managed to do so?

These players all play Phoney 1 Club in a 5-Card Major System. Not wanting to get too high opposite a bust hand, they all open with a Phoney 1. After a positive response, they make a jump with their second bid. Depending on the size of the actual hand, the jump will either be on level-2 or level-3, the point being that they are showing the 5-card suit which inevitably ends up as trumps. Responder with a bare minimum usually passes the 2-level jump. A 3-level jump always goes to game. With a negative response they simply keep bidding the 5-card suit at the lowest possible level until the opponents pass. When the 5-card suit is , the auction more often than not dies in 2. When the 5-card suit is , the opponents often overbid to 2 which ends up going down. Either way, their side ends up with the positive score.

I doubt that I can convince you but:
Without PS, I have two possibilities:

1. I am not able to open a 5332 hand with the right NT range in NT. This is particular ugly, if I hold 22+ HCPS and will fear that my 1 bid may be passed out. Another solution would be to open such a hand with your equivalent of an ACOL two. This is possible, but will burden these handtypes into your ACOL two. In the system I play, all these bids are bundled together with all even stronger hands in my 2 opening. So, even now, there are too many hand types for one opening, I am happy about any hand type, I can exclude.

2. You may open 2 NT with the 5332 hand without the possibility to ask for a five card major. This is what GIB is doing. This is entirely possible, but sometimes you pay for just being in the wrong game/slam.


You may argue that this price is low. But what exactly do I miss, if I play PS compared to normal stayman? To me, there are so low, that they do not count a lot in real life.


Or you can play a 5 card stayman without puppet over 2N.

One very common in the UK a few years back and fairly common now:

2N-3-
3 = no 5 card major, but also not 2/2-3
3M = 5 card suit
3N = 2/2-3

Over 3 the standard continuation is to bid 4 card majors held, but I think it's theoretically better for responder's 3 to deny 4 hearts (or show 5/4 if you remove 3N to 4) and opener to bid 3 if he has 4 of them.

The only holding that's awkward here is 5 cards in one major and 3 in the other. We normally transfer as it's more often important to play in the 5-3 fit if it's the weak hand's suit.

Over 1N this is sometimes recoverable, auctions like 1N-2-2-2N-3-4 are not unknown.

I don't play PS in the way you've described it. I am trying to explain that you seem to missing the point of it and hence your reasons for dumping it are (IMO) wrong, and your posting style is a little irritating at times.

Isn't this just a simplified version of Polish club? When I said if you don't like opening 2NT on a strong balance hand, then play a strong 1C/1D system instead, I should have added ...or a Polish club/carrot club/3-way club system. An artificial 1C opening solves lots of problems. It also creates other problems - if it didn't, the world would be playing it.
