Since you posted in the expert forum, I'll assume that you are typically better than your partners.

 

I find that it is much easier to put partner in their comfort zone and get the most out of them if I play what they are comfortable with, so I basically let my partner pick the conventions we play in any non-serious/casual partnership, though I do often nix things like Flannery or mini-roman in those partnerships even if my partner wants to play them because they require follow-up discussion more than what a pick-up partnership usually is willing to put in.

 

When starting a serious partnership, I will ask if partner already has a system that they want to play - if so, I'll volunteer to look it over, and if its playable, I'll probably play it. That being said, in a serious partnership I am much more likely to propose tweaks and pet gadgets of my own if they do not seriously impact the rest of the system. That tends to be much more give and take.

 

The thing that is most important to me, however, is to nail down carding agreements. Even there, I have my pet stuff I like - one of which is that if I lead a trump, the spot I use will have suit preference implications if I can afford it - that has never cost matchpoints, and has gained significantly in some situations. Its also something that opponents rarely ask about, though if they do ask about leads in a trump contract when partner led a trump, I am sure to tell them about the suit preference implications.

 

Anyway, I hope that I answered your quention.

*** Do you have a big dot "SPECIAL CARDING PLEASE ASK" ?

Amazes me opponents even if they look never ask.

Rusinow honor leads, unless count honor lead.

3rd and 5th with special exceptions.

Upside down att cnt, sp with special cases when att is OF, then even cnt is OFF.

Parity echo in trump or designated next suit.

Periscope count.

Not all I use but I have seen and un asked.

Around here, the most frequent happening is that declarer, on the opening lead, asks "what are your leads?" and on the defenders' first discard "what are your discards?" Sometimes you'll hear "what is your carding?" The most frequent answer to the first question is "standard", to the second "odd/even", to the third "standard, odd/even discards". Nobody ever asks for further information. I've never seen the "big dot" colored in or whatever, even if they're playing something esoteric.

I always color in the big dot for Special Carding Please Ask. No one asks.

In some partnerships, I employ unusual carding conventions, detailed on our system-card.

• Most declarers (like me) don't ask: they know they can't absorb and use a lot of new information, just for a few boards :(
• Good declarers ask and use the information to better effect than defenders :( :(
• Better declarers don't ask but surreptitiously study a defender's card to acquire the same knowledge. They hope to lull defenders into a false sense of security, so that they continue to signal too much and too honestly :( :( :(
• I'm told that top declarers continually update a mental database of defenders' signalling propensities. This is especially useful against defenders who "sometimes false-card", which declarer may suspect to be a euphemism for cunning concealed partnership understandings. For instance, in specified circumstances, defenders reverse their signals. Presumably, a declarer who can suss out this ruse is at less of a disadvantage :)

I think you are asking how you can find out what it means to play '2/1'.

 

Unfortunately, saying 'I play 2/1' isn't telling anyone much. It does mean that most 2/1 responses are forcing to game, but some people play that a response of 2♣, if followed by 3♣, is not game forcing, as one common variant.

 

It used to mean that a response of 1N to 1M was forcing one round, but a lot of good players now use semi-forcing even by an unpassed hand, using 2♣ as either game force, or a 3 card limit raise of the major.

 

Even if you find that most do play 2/1 IS gameforce, and that 1N over 1M IS forcing 1 round by an unpassed hand, you still have only scratched the surface.

 

I play variable 1N openers in a 2/1 structure, while 15-17 is the most common and some play 14-16. The response structures to 2♣, and to 2N and even to 1N are almost infinitely variable, though there are some treatments that are more common than others.

 

The simple answer is that there is no one way to play 2/1: 2/1 describes a general philosophy or style, but it is a large tent.

 

My advice: look online to find a fairly modern text on 2/1. Don't treat it as infallible and don't assume everyone has read it. Whenever playing with a partner for the first time, ask some specific questions. I'd ask, in no particular order:

 

signals and carding? Leads against suits and notrump? Responses to 2♣? How high do we play negative and responsive doubles? 1430 keycard? opening 2d is? Responses to weak 2's? Do we play walsh? (do we bypass a diamond suit to respond in a 4 card major to 1♣, with a limited hand?) Responses to 1N (4 suit transfers? Texas? Jacoby?), and responses to 2N. Bergen raises? Lebensohl?

 

This is just a list that I thought of as I was typing: your list would probably be different.

 

I played a couple of weeks ago with an old friend, a very good player. We hadn't played in at least 15 years. We were able to cover most of our methods in about 15 minutes of discussion, tho a couple of things came up during the day that we had to talk about. Online, it isn't usually possible to do this.
