Here is a comment by Fulvio Fantoni: Risposta di Fulvio Fantoni Dear Giovanni, I'd like to precise that the book you quote hasn't been written by Claudio or me, but by a third person. This person watched our play and tried to deduce our system and was able to reconstruct many bidding sequences exactly, but not all of them. In the case in point, the bidding sequence you report is not correct. For us 2NT in that bidding sequence means 14+, 5+ e 4+ hand. Anyway, you should know that this is going to change very soon, because we want to introduce transfers at 2 level, too. Best regards :) Fulvio
