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

I use look at it during games so that I won't have to remember everything.

It should be pretty comprehensive. Generated using AI (latex , can share the tex file as well).
There is printable version and colored one.

Included:

  • Regular Responses and Rebids: Per Standard 2/1 bidding system

  • 1NT forcing system

  • Competitive bidding arsenal: Cappelletti , Michaels cuebids and Unusual 2NT, overcall strategies

  • Multiple double types: Takeout, negative, responsive, support (X/XX), and maximal doubles

  • Inverted minors, new minor forcing , and other conventional bids

  • Advanced slam bidding: Roman Key Card Blackwood 1430 with void-showing, control-showing cuebids with bypass logic, serious 3NT convention, and Last Train

  • Defensive foundations: signals, opening lead strategies


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

Enjoy!

It sounds like a resource that would be useful for online play

So long as your opps know that you’re using notes during the auction, no problem. But in any kind of serious game, you’re cheating if you’re not disclosing. Ok, I do understand that looking at system notes while playing is one of the most common breaches of how one is supposed to play, but that doesn’t make it right…again, if the opps don’t know. Personally, I play a 15 board set practice match once a week, and we all talk about what’s going on and I’ll have my 160 pages of notes at hand…but usually I can’t find the bit I need in time, lol


As for whether you’ve made any mistakes…system choices aren’t really mistakes unless you have two contradictory notes. I would say, however, that I don’t think there is a good player anywhere in the world who plays cappelletti over 1N. I think the reason so many non experts play it is because it’s what the GIB robots play on BBO. It’s theoretically unsound. Having to bid 2C on any one suiter makes it difficult for partner if responder bids, and using 2D for both majors means partner has to guess when he holds equal length, unless 2D promises 5-5, which is too restrictive specially at favourable vulnerability. There are many better methods. Multi Landy or Meckwell are both fairly popular amongst more advanced players

When I started to play tournament bridge in the 1990s in California, virtually everyone was playing Cappelletti and/or DONT vs. notrump openings. This was around the time BBO came into existence and well before the popularity of robot bridge. In fact, even when I left the US in 2017, Cappelletti was a pretty common defence to notrump in local clubs and tournaments (at the time, ACBL still disallowed the multi-landy 2 overcall in most events).

While I agree with you that Cappelletti is not a very good defence, I don't think the reason non-experts play it is because of robot bridge. The non-expert game is usually a number of years behind what the top players do, and ACBL's restrictions on allowed methods slow the process even further. If anything, the robots play Cappelletti because it's popular and most people know it. It would be pretty easy to program the robots to play something else; in fact there's a regular robot game on BBO ("Challenge des Villes") where the robots play French Standard.
