The Blackwood convention

A bid of 4NT is usually asking for Aces (always after a suit fit has been found). The responses are:

  • 5 ♣: No Aces
  • 5 : One Ace
  • 5 : Two Aces
  • 5 ♠: Three Aces
  • 5NT: Four Aces

Roman Key-card Blackwood is an optional alternative to the above

Showing controls

These bids may only be made from 3 ♠ upwards in the case of a fit in Hearts, or correspondingly higher for fits in other suits. For example, after the sequence 1 , Pass, 1 , Pass, 3 , Pass, a bid of 3 ♠ shows a control in Spades. In any other sequence 4 ♣ is the lowest possible control showing bid
