akwoo Posted September 15, 2015 Report Share Posted September 15, 2015 Where is this not allowed? I'm too lazy to look this up right now, but I'm sure the ACBL requires you to play the same system throughout a session. Quote Link to comment Share on other sites More sharing options...
mycroft Posted September 16, 2015 Report Share Posted September 16, 2015 From the ACBL Alert Procedure: 1) “TWO-SYSTEM” METHODS Some pairs vary their system by position, by vulnerability, or a combination of the two. While this is legal, it is also something the opponents may need to know ahead of time. One example of this is agreeing to play a forcing-club system not vulnerable and “two over one” vulnerable. Minor variations such as varying notrump range or jump overcall strength by vulnerability do not require a pre-Alert. These methods still require normal Announcements (notrump ranges; transfers) or Alerts (forcing Stayman over some notrump ranges) when appropriate. As an aside, please note that it is not legal to vary your system during a session for subjective reasons, such as the skill level of the opponents which you happen to be playing at the time or which member of the partnership is making the call. You may, of course, alter your defenses in response to the opponents’ methods. Italics in original, but here, it's equally the emphasis of the situation. That doesn't mean I haven't seen "Your Card" or "Caddy Club" - just not in any game where we actually care. Quote Link to comment Share on other sites More sharing options...

It can easily be determined objectively what system is used. Rik Quote Link to comment Share on other sites More sharing options...
steve2005 Posted September 16, 2015 Report Share Posted September 16, 2015 OK i'll bite. What's Caddy club? never mind foundA few years ago, it was common in the NABC midnight zips for junior experts/pros to play with caddies who barely knew how to play. They played asymmetric systems where the caddy's bids were all transfers, the pro's were all natural, so the pro would always declare.

kwiktrix Posted September 21, 2015 Report Share Posted September 21, 2015 4CM just doesn't catch on, with many players. You can play EHAA and have a largely similar system... 1X isn't forcing, but it's close.Wasn't aware that their system used 4cM openings...

Sorry for expanding the context without warning. Quote Link to comment Share on other sites More sharing options...
