Thanks VERY much. Nope--not a life master. Ended up with about 50 MP, playing in local clubs back in the late sixties into the seventies. Never heard of SAYC--so there will be some studying before wading in. I was past Goren, but...

I just encountered one pair who wanted to do a "do-over" and the other side wouldn't let them, so one guy quit. Seems to be table talk too. Appreciate the guidelines. Off to study SAYC!

Welcome to the forums (and back to bridge!)
I wouldn't study SAYC in any detailed sense (I don't think anybody actually plays that...I know that I don't even know it). A lot of people play a "natural" system with 5 card majors, 15-17 NT, and either game forcing or forcing 1 round two over one bids (e.g. 1S-2D). They call that system SAYC or 2/1 (if 2 over 1 bids are game forcing).
Most people play transfers of some kind over NT openings.
If you're confused whether your partner means a bid as artificial, most people don't mind if you ask, especially with a pickup partner. Also, people play a few different forms of blackwood ace asks, so you may want to check with your partner when it comes up.
Besides that, most things (for some definition of "most") are just natural. Have fun!
