Have just been reading Sally's summary of SAYC - which my partner and I play a (simple) version of. I'm particulary interested in the (no opps bidding) 1NT-2C-2H-3C auction where 3C is slam interest in clubs. This implies that the 3C bidder doesn't need to have 4 hearts or 4 spades for his stayman bid. Therefore the 3C bid has effectively changed the meaning of the stayman bid. My question is therefore is 3C alertable (and would you say something like slam interest in clubs and could be that partner doesn't have 4 of a major) and if opps dont ask what it means, should declarer tell them after the auction and before the lead as they have misinformation.
