Wanted to share my cheat-sheet that uses standard 2/1 conventions, with some that I like more.

It should be pretty comprehensive. Generated using AI (latex , can share the tex file as well) .

Enjoy!

PS. Also let me know if there are any mistakes in there.

At very first sight, there is some discussable stuff in there (although quite possibly still standard for intermediates in NA):

- Cappelletti instead of the much sounder MultiLandy
- the dreadful 2NT response to 2 showing points and a balanced hand
- pessimistic and over-generalized requirements for 6 and 7 level
- vague and unrealistic Penalty double

Thanks. To the point(s):
- hmm, it seems better. hard as it is to find partners that know Cappelletti.
- what is your suggestion?
- yeh, might remove that. Know what to check.
- removed in my version.

Btw, did I miss any important sequence?

If you mean that Cappelletti seems better than Multilandy, then I respectfully suggest you are nuts :) Check out the system cards of pros to see how many play which.

My suggestion for 2C-2NT? Both minors, or anything equally unlikely. The important thing is not to preempt the opener by making it near impossible to describe his hand in time and by wrongsiding NT. If both hands are balanced and there is a quantitative decision to be made then it is Opener who should be describing his range and Responder who should be deciding.

I skipped over a lot of the sequences and stuff like Jacoby 2NT which I dislike but understand are still the works over there.

The control-bid section is a bit of a mess, with no decision about how to use 3NT within a sequence and some AI nonsense in the examples.
