blackwood? ok what's the suit?

The problem with SAYC is that it is not that "standard." If one looks at the ACBL SAYC booklet: (http://web2.acbl.org/documentlibrary/play/SP3%20(bk)%20single%20pages.pdf), a rebid by opener of 3 Clubs is 13 to 18 and, hence, is not necessarily game forcing. In that case responder's 4 Clubs could be considered invitational agreeing to Clubs. If responder is afraid 4 Clubs will lead to pass or 5 Clubs, then a skip to 4NT is understandable. That being said, most better players would consider 3 Clubs as game forcing and as pointed out in posts above, 4NT could be quantitative.

 

So, in a regular partnership whether 3C is a game force has to be discussed as well as what 4NT would mean here. With casual online play its just a guess. A common agreement for 1430 is that absent suit agreement one should answer for the last bid suit. Responder should be able to handle that no matter what.

Under "Slam Bidding", the SAYC booklet says "Blackwood 4NT is used to ask for aces." This is simple Blackwood, not keycard.

In SAYC, yes. OP said they play 1430.

Actually, what the OP said was "SAYC and 1430". So they aren't playing SAYC, and to say they are is an error.

Common mistake, many people call 5card majors and 15-17 NT "sayc".

No it isn't. The SAYC document is only a summary, and really can't be used to learn SA completely. A rebid of 3c has always been termed a "high reverse", and reverses are 16+, 17+ in SA.

 

It's massively impractical to rebid 3c on a 13 count; since responder promised a rebid, you'll often be in 3nt with 12hcp opposite 11 or even less the way people open & respond these days. Also having such a wide range makes it impossible for responder to know what to do with say 15-16 pts, since if opener can have a bare min, he doesn't want to beyond 3nt, while if opener promises extras the quantitative 4nt is in order if no black suit fit.
