Blackwood - 4NT

Blackwood in bridge is one of the most commonly used bridge conventions and an important slam bidding tool. The Blackwood 4NT convention is used when you are thinking of bidding a slam and want to find out how many aces partner has.

Asking for Aces

4NT asking for aces

4NT asks partner to show the number of Aces in his or her hand. 4NT is not a bid you would normally make in a natural sequence which makes it easy to remember that something funny is going on!

Notice that the responses start from the lowest available bid. After hearing partner's response you will normally now be in a position to decide whether or not to bid slam.

This hand has good trumps, honor cards in partner's suit, an excellent side suit in clubs and a singleton. Slam is a definite prospect. But partner has no aces, so slam is hopeless and you have to be content with 5♠ losing the A and the A.

This time North shows 1 Ace and South bids the slam.

Asking for Kings

If your side has all the aces, you might like to know how many kings partner has. You should only ask for kings if you are interested in bidding a grand slam, where you need all 13 tricks. Bidding 5NT promises that no ace is missing.
