Royal Bengal Card - Checkback Stayman

Checkback Stayman

This is a method for responder to determine if opener is holding 3 cards or less support in responder’s major suit.

• 2♣/3♣ after 1NT/2NT rebid by opener is always Checkback

• Responder may or may not have 5+♥/♠ to request openers major holding

• Should opener deny 3 card major, responder may still rebid major with 6+ suit, invitational values
