Gerber Convention Bidding

A bid of 4C after partner's 1NT, 2NT, or 3NT bid is 'Gerber, asking for aces'. It is an artificial bid, not a true club bid. Partner's response is a 'coded' message:

4D = 0 or all 4 aces
4H = 1 ace
4S = 2 aces
4NT = 3 aces


Partner can now bid 5C to ask you for Kings.

5D = 0 or all 4 kings
5H = 1 king
5S = 2 kings
5NT = 3 kings


This can definitely help you reach slam!





    *Gerber was originally used only after a notrump bid. Over time, players began using it for suit contracts too as it keeps the bidding lower than using Blackwood. It can cause confusion however as whether 4C is asking for aces or just a natural Club bid.

    A common agreement is that 4C is always asking except when Clubs have already been bid. Players that use cuebids for aces do not need to use 4C as Gerber, their Club bids are always natural for them.
