Blackwood 4NTFebruary 14, 2017
The Gerber convention is used to ask for aces after a 1NT or 2NT bid from partner
- 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.
- 5♦ = 0 king or 4 kings
- 5♥ = 1 king
- 5♠ = 2 kings
- 5NT = 3 kings
