I just saw that. I'm a four-card-limit-raise believer since all the teaching materials(books/softwares) about bridge I have tells me not to make a limit raise with 3 trumps. I guess that's the reason I desperately need that 3S to be non-forcing here.

OK, this explains something. I thought they were the same...

Do we have to have 4 trumps to make a limit raise?

Thank you for your information:)

I always think the 3S here is non-forcing in SAYC. However, one very experienced player insists that this is a forcing sequence in SAYC. He asked me to give him "proof" that it's non-forcing and I couldn't. So what's your opinion?
