  1. Improvers Bridge Lesson 9 Review of Blackwood

  2. Blackwood • There are 2 versions: • Standard Blackwood • Roman Key Card Blackwood (RKCB) • Make sure you know which version your partnership is using!!!

  3. Blackwood Convention • When partner bids 4NT • Although a Conventional Bid do NOT alert • No alerts above 3NT • The 4NT bid says: • How many top cards have you?

  4. Standard Blackwood • 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

  5. 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 • If a Grand Slam is likely • But only do this with all Aces present • You are committed to at least a small slam • 5NT promises that all suits are safe

  6. Standard Blackwood • Partner asks for Kings by bidding 5NT • Responses are: • With 0 Kings bid 6 • With 1 King bid 6 • With 2 Kings bid 6 • With 3 Kings bid 6 • With 4 Kings bid 6NT

  7. Roman Key Card Blackwood • King of trumps is counted as a top card • So 5 Key Cards • 4NT asks how many of these do you have • Partner then responds: • With 3 or 0 Key Cards bid 5 • With 4 or 1 Key Cards bid 5 • With 5 or 2 Key Cards, no Q trumps bid 5 • With 5 or 2 Key Cards, + Q trumps bid 5 • Remember the sequence 30, 41, 52

  8. RKCB • Partner asks for Kings by bidding 5NT • But not including the trump King • Responses are: • With 0 Kings bid 6 • With 1 King bid 6 • With 2 Kings bid 6 • With 3 Kings bid 6

  17. 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

  18. 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!

  19. Stopping in 5NT The Bidding Goes 1 2 5 5NT  K  8 Partner opens We have 20HCP! Bid 2 to see what happens Shows minimum opener RKCB Missing 2 aces Must stop at the 5 level Bid next suit up Partner bids 5NT 2 4NT 5  K  Q  A  K  T  5  4  3  Q  3  K

  20. Stopping in 5NT The Bidding Goes 1 2 5 5NT  K  8 Partner opens We have 20HCP! Bid 2 to see what happens Shows minimum opener RKCB Missing 2 aces Must stop at the 5 level Bid suit above partners Partner bids 5NT 2 4NT 5  K  Q  A  K  T  5  4  3  Q  3  K

  21. 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!!!

  22. 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

  23. 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!!!
