I,m intrigued to read that the opener has 5 clubs promised by this sequence. This could help us with our opening leads. Does the sequence starting with 1D promise 5 diams in the same way please?

As an Acol player I do not understand this frequently seen SAYC sequence by the oppos: 1C - 1NT 2S - 2NT 3NT What does the 2S indicate? Surely the 1NT bidder has denied a 4 card major? How does the 1NT bidder grow his 6 point minimum into 11 hcp for his 2NT bid? How does the 3NT bidder raise the 6 point holder up to the desired 25 total? Thanks to all who can solve this for me!

I recall an empirical "law" that said that if you had a long suit then maybe that was the same pattern in other hands. I have looked for more info without success. Any ideas please? I believe it wasn,t true.

Can someone please direct me to the data on the frequency of a two suited fit (8+ cards). I have looked around but not found it. If I had to guess, I would think it was 1 in 50 hands, whilst a 1 suited fit would be 8/10? Thanks
