Gerber is a convention we use directly over
No trump to ask for aces and kings. Generally, if you partner opens 1NT
and you bid 4C this is Gerber and you should respond as follows:
0-4 Aces --
4D 1 Ace --
4H 2 Aces
-- 4S 3 Aces --
responder then bids 5C he is asking for Kings. Any other bid by him
including 4nt is a signoff. Gerber can be used when partner bids 2C
and then rebids 2nt or when he jumps to 2nt after he opened the bidding on
the one level. Caution: When playing splinters an
Unusual Jump to 4C is not Gerber.
Standard Blackwood also in a means we use to ask for
Aces and Kings. A bid of 4nt asks opener for Aces.
These are the
Aces -- 5C 1 Ace
-- 5D 2 Aces
-- 5H 3 Aces --
If responder then bids 5NT he is asking for Kings. To exit this
Blackwood the responder must bid a suit that hasn't been mentioned in the auction.
Roman Keycard Blackwood is a modification of Regular Blackwood and will be discussed
