Review of Blackwood


Blackwood

Blackwood

  • There are 2 versions:

  • Make sure you know which version your partnership is using!!!


Blackwood convention

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?


Standard blackwood

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


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

  • 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

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

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

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!!!
