GIB's 2♠ promised 4-card support, but delivered only Qxx.

I cannot find any section on simple raises in GIB system notes.

I've commented that the system notes are grossly indequate but they are too lazy to fill in as much as is possible.

I have every reason to believe that BBO developers possess a faultlessly robust work ethic.

An issue I raised in another post was explained by the system notes, and the reason I mention
the notes here is to confirm I did check them this time.

Although I have no experience in such matters, I have read an interview of a former multiple
world champ who said his partnership's notes were over 200 pages long. I do think that GIB
refinement would best serve most customers by keeping complexity to a minumum.

We just had a discussion of 3-card raises a few days ago. The bid shows 4-card support, but sometimes you have to bid it with only 3-card support.

GIB has a number of meta-rules that allow it to look for bids that almost match the hand it has, if there are no bids that match it exactly. This includes bidding with a fit 1 card short of what is promised, or +/- 3 HCP. This is basically a translation of what human players call "finding the smallest lie".

If we accounted for this in the explanations, they would get very vague, because the cards shown would always be shorter than what most players expect, even though these are infrequent, and the point ranges would be very wide.
