If you open 1NT with say 5 's and 2 's (so 2533) and partner transfers into 's,
how can you subsequently find a possible 5-3 fit if partner has game values and, say, 5332 shape? I bet you would be playing it in 3NT?

And just have a look at all of the question marks that follow. How many can you confidently answer - and be sure that your partner gives the same answer? How many gaps will you leave?

It's high time that all of this was clearly defined.

So here it is, all in one book. And you will find the completed charts at the end of the book, so you know that everything is covered. And if you want to know what 3means in the sequence 1NT - 2 - 2 - 3 , just look it up in the bidding index.
