Chapman/Judy Relays

1NT - 2 Responder could have:

• A weak 5-5 minor hand
• A weak single suited minor hand
• A slammish hand with one or both minors

Opener assumes that responder has a weak 5-5 minor hand and bids:

• 2NT says I prefer clubs
• 3 says I prefer diamonds

Responder with the weak hand bids a minor to play

After opener's rebid:

• 3 bid by responder is a slam try in clubs
• 3 is a slam try in diamonds

Opener bids

• 3NT with only a doubleton and no slam interest. However responder can push on by cuebidding .
• With support for the minor, opener cuebids up the line.
• 4 is not a cuebid (when clubs the suit) but is keycard gerber. 4 is keycard when diamonds are the suit.
