Bidding the Blackwood Convention

Blackwood is used when you and partner have chosen a trump suit and think that you also have enough points to bid a small or large slam. The only thing holding you back is if you are missing an Ace or two.

A bid of 4NT after a trump suit has been agreed upon is Blackwood "Asking for Aces". It is an artificial bid, not a true notrump bid. Partner responds in 'code':

5C = 0 or all 4 Aces
5D = 1 Ace
5H = 2 Aces
5S = 3 Aces

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

6C = 0 or all 4 Kings
6D = 1 King
6H = 2 Kings
6S = 3 Kings

This can really help you reach slam can't it!
