New Minor Forcing
This is a technique to be used by the responder in order to show his 5 card major with a good hand.
♠ D 9 ♥ D V 8 5 2 ♦ A V 4 ♣ D 8 5
The responder with the above hand will respond 1 Heart to 1 Club openning. And how will he show that his major is 5 cards with a good hand if the rebid of the opener is 1 NT? He will bid 2 Diamonds. This will show his 5 cards Hearts with at least 11 HCPs. This new minor is not necessarily a 4 card suit.
