Gerber 4♣

The Gerber convention is used to ask for aces after a 1NT or 2NT bid from partner
Responses:

  • 4 = 0 ace or 4 aces
  • 4 = 1 ace
  • 4 = 2 aces
  • 4NT = 3 aces

Asking for aces with Gerber 4

Gerber 4 is normally used directly over a notrump bid, usually with an unbalanced hand. It is useful when you think you’re strong enough for slam, but just want to be sure you’re not missing 2 Aces.

After the reply, you will now be in a position to decide whether or not to bid slam. If you don’t have enough aces to bid slam, you can stop in 4NT. This is a natural bid.

If you have a balanced hand but you’re not sure whether you are strong enough for slam you can use the Quantitative 4NT.



As soon as North opens the bidding, South is interested in a slam. But the 4 response shows 1 Ace and South has to be content with game.


This time North shows 2 Aces and South bids the slam.

Asking for Kings – 5

You should only ask for kings if you are interested in bidding a grand slam, where you need all 13 tricks. You don’t normally need all the aces and kings to bid a small slam.

The responses are the same over 5 as they are over 4, just one level higher.

Responses:

  • 5 = 0 king or 4 kings
  • 5 = 1 king
  • 5 = 2 kings
  • 5NT = 3 kings
