  • Top cards are the 4 Aces
  • With 0 or 4 Aces bid 5
  • With 1 Ace bid 5
  • With 2 Aces bid 5
  • With 3 Aces bid 5
  • These bids say nothing about the suit bid
  • They reply to partner’s request
standard blackwood1
Standard Blackwood
  • Partner knows how many Aces you hold
  • And whether to bid a slam (12 tricks)
  • Or look for a Grand Slam (13 tricks)
  • Partner can bid 5NT to ask for Kings

when do you bid the slam
When do You Bid the Slam?
  • If you have all Aces or all Key cards present bid the slam
  • And think about asking for Kings
  • Missing 1 Ace or 1 Key card
  • Bid it with good suit(s) to run
  • Using RKCB bid it if you hold the trump Q
  • Missing 2 Aces or Key cards
  • Stop at the 5 level
stopping at the right level
Stopping at the right level
  • You think a slam is on
  • But not in partner’s suit
  • So you bid 4NT
  • Expecting to get to 6NT
  • But you are missing 2 aces
  • How do you stop in 5NT?
  • When 5NT asks for Kings!

Stopping at the 5 level
  • If partner initiates Blackwood
  • You respond
  • Then partner bids a different unexpected suit
  • You MUST bale out in 5NT
  • Partner’s suit bid is not a natural bid
  • So do NOT leave it in!!!
blackwood or rkcb
Blackwood or RKCB
  • Blackwood is slightly easier
  • Blackwood is universal
  • RKCB gives you more information
  • Making judgement on bidding the slam more accurate
  • If you play RKCB all the time it becomes the norm
  • RKCB can give you an edge
summary
Summary
  • You MUST use one or other version
  • I strongly advise RKCB
  • Don’t panic when partner bids 4NT
  • All you have to do is make the correct response
  • Partner has the difficult job to decide where to stop
  • Bidding and making slams gives tremendous satisfaction!!!
