How to signal when a new suit is played in a NT contract.
When he plays a new suit, the leader's partner uses the same signal system :
He plays :
- The 4th best card in a long suit with an honor
- The 2nd card in an honorless suit
- The highest card out of 3 low cards
- The middle card out of 3 cards including an honor
Example : You are South. West plays 3 NT. Your partner has led
♠. But it appeared
♠ is not a good suit for your camp. When you take the lead, you want to play
♣. Which card do you choose ?
♣. During a NT play, you play a new suit. Follow the same rule as if you lead the 1st trick : the 4th best card (with an honor)
