csdenmark Posted March 10, 2005 Report Share Posted March 10, 2005 I need the definition of convention '6 aces Blackwood'. Could it be 'Byzantine Blackwood'? Anybody who will be able to help? Quote Link to comment Share on other sites More sharing options...
HeartA Posted March 10, 2005 Report Share Posted March 10, 2005 I need the definition of convention '6 aces Blackwood'. Could it be 'Byzantine Blackwood'? Anybody who will be able to help? If you use 6 Aces (keycards) blackwood, you need to establish 2-suit fit first:1♠-2♥3♥-3♠4NT This 4NT is 6-keycards blackwood. As how to answer it, you may discuss with your pd.

Rebound Posted March 10, 2005 Report Share Posted March 10, 2005 It's really just an extension of RKB where there's a double fit so one more K and Q. According to Eddie Kantar in Roman Keycard Blackwood - Slam Bidding for the 21st Century, the steps are as follows, although, of course, your partnership may have different ideas:1st step - 1 or 4 (out of 6)2nd step - 0 or 33rd step - 2 w/ neither Q4th - 2 w/ lower ranking Q5th - 2 w/ higher Q6th - 2 w/ both He recommends holding 3 keycards to use RKb in a double agreement sequence due to the large number of responses potentially getting too high otherwise. Note that a cue bid of the second suit does not equal double agreement and applies "only when you support your partner's suit and your partner immediately supports yours...." I just happened to have the book handy so I thought you might find it useful... Quote Link to comment Share on other sites More sharing options...
csdenmark Posted March 10, 2005 Author Report Share Posted March 10, 2005 Thank you both - I will look Kantar up - I think I have his books. The only option I was able to find was Byzantine Blackwood and it might very well be correct as that convention should have responses similar to RKCB. This convention is used in 3 cases in Icelandic Precision - a rather complicated symmetric relay system. I have stated the sequences below: 1NT-2♥=#Trans->♠ *5+♠ *5+-4+,minors *4♠+5♥ 1NT-2♥-2NT=MAXIMUM,S:4cd,better♦ 3♣=To play 3♦3♦=GF,Both minors,H:Single/void3♥=Re-transfer -> ♠3♠=Single/void3NT=*2-2-4-5 *2-2-5-44♣=*2-1-5-5 *1-2-5-54♦=*1-1-5-6 *1-2-6-54♥=Void,Slam?4♠=Void,Slam?4NT=6 aces Blackwood5♣=Signoff5♦=Signoff -------------------- 1NT-2♥-3♣=MAXIMUM,S:4cd,better ♣ Pass=Signoff3♦=GF,Both minors,♥:Single/void3♥=Re-transfer -> ♠3♠=Single/void3NT=*2-2-4-5 *2-2-5-44♣=*2-1-5-5 *1-2-5-54♦=*1-1-5-6 *1-2-6-54♥=Void,Slam?4♠=Void,Slam?4NT=6 aces Blackwood5♣=Signoff5♦=Signoff -------------------1NT-2♥-2♠-2NT=Minor,2-suiter 3♣=Best minor3♦=Best minor3♣♦-3♥=Single/void3♣♦-3♠=Single/void3♣♦-3NT=*2-2-4-5 *2-2-5-43♣♦-4♣=*2-1-5-5 *1-2-5-53♣♦-4♦=*1-1-5-6 *1-2-6-53♣♦-4♥=Void,Slam?3♣♦-4♠=Void,Slam?3♣♦-4NT=6 aces Blackwood3♣♦-5♣=Signoff3♣♦-5♦=Signoff Quote Link to comment Share on other sites More sharing options...
han Posted March 11, 2005 Report Share Posted March 11, 2005 I also play 6-keycards RKC when one partner has shown a balanced hand and the other partner has shown a 2-suiter. In case of a double fit, we only count the queen of the higher ranking fit. Not perfect, but simple. Quote Link to comment Share on other sites More sharing options...
