The 2/1 GIB CC (I followed the first link at https://www.bridgeba...ystem_notes.php) does not tick the Drury checkbox under the sections for Major Openings. Yet when I examine some bidding by robots on "Practice > Just Declare", they use 1M 2C and explain this as Drury. Is the Convention Card out of date? Or are the "Just Declare" hands based on a different software version?

If I enter an individual tournament with a Robot partner, is this the applicable convention card?

What am I missing?

Thanks

That CC is well out of date. The actual system notes page you linked to are closer, and describe Drury at the bottom.

I believe it plays an approximation of reverse(?) Drury

I do often try to cross-reference GiB bidding options with other documentation around conventions but cannot be sure on subtle differences

I tend to rely (rather dangerously) on the bid descriptions before I bid

However I have just checked and you are correct that the CC is not accurate (on much)

I think the system notes are fairly accurate
