Hi, everyone. We use BBO advanced 1.2 convention card.I have two questons to ask. Anyone can answer me? (1) In partnership bidding, 1♥-1NT-2♠-3♠: Why does this "3♠" have to reach 7 cards of Spade? (2) Also in parternership bidding, 1♥-1NT-2♠-2NT: Why does this "2NT" have to reach 6 cards of Spade? :P Thanks for your useful opinion for us. We appreciate that very much. ))
