Glad I don't play it then, everybody I've met (and noticed) in the UK playing SA seems to use it as part of the system with the exception of 1♣-1♦-1♥-1♠
"SA" (Standard American) is not "SAYC" (Standard American Yellow Card).
SA is like saying "Acol" -- four or five card majors? What's your 2-bid structure? How do you respond to Multi 2D? etc. SA is a very-much-up-to-the-partnership collection of gadgets and styles they choose to suit themselves, with some of the few constraints being that it's typically a 5-card major, strong NT "system".
SAYC on the other hand is a very well-defined set of conventions and treatments. It was developed (to the best of my knowledge) by the ACBL to allow partnerships to play a certain set of conventions (5-card major, strong NT based) with a minimum of gadgets (weak twos, Jacoby, Stayman, etc.) that allows for very little deviation (example: Want to play 2D opening as something other than weak? No can do. Bergen raises? Sorry.). See the card at
http://web2.acbl.org...y/sayc_card.pdf , or do a search for the SAYC system explanation in .pdf.
This allows for a new partnership to sit down and play together with less chance of misunderstanding, and helps speed up certain games at tournaments, especially when only SAYC is allowed. It's called SAYellowCard because the convention card is supposed to be printed on yellow stock to make it easy to know your opps are playing SAYC and not some "complicated" system.
