Side question: Since you have both black Aces, what does that say about partner's hand ? Quote Link to comment Share on other sites More sharing options...
manudude03 Posted March 1, 2014 Report Share Posted March 1, 2014 6C or whatever shows 1, partner may well be v KTxxx AKQJxxxx v or something. Partner can bid 6D to ask whether it is the queen or A/K. Quote Link to comment Share on other sites More sharing options...
Siegmund Posted March 1, 2014 Report Share Posted March 1, 2014 With my usual partner, 6C=0, 6D=Q, 6H=A or K, higher=2 of top 3. But "whatever shows 1" has to be the right answer. We don't know why partner asked, just that he had 21 other calls between 1H and 5NT available if he had wanted to find out something else.

Finch Posted March 1, 2014 Report Share Posted March 1, 2014 Whatever my agreement is. For me, 6C shows the A or K, 6D the Q and 6H none (6NT 2), so I will bid 6D. The same answer as Siegmund, but from the opposite direction. Partner must be 0580 or similar. Quote Link to comment Share on other sites More sharing options...

Partner can bid 6D to ask whether it is the queen or A/K.You were pretty close to the hand: voidK 10 8 x x xA K Q J x x xvoid I just took a stab at 6H ( over partner's 1H rebid ) since I had no GSF "enhanced system" . But I should have played Culbertson's "plain vanilla" GSF just in case partner had BOTH A and Q to end in 7H .- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - So far, I think Frances' "opposite direction" system is best ...

ggwhiz Posted March 1, 2014 Report Share Posted March 1, 2014 6C shows the Queen or less and then 6D asks for it6D shows 1 of the top 26H shows 1 of the top 2 with extra length That's all I learned many years ago and I'm still waiting to use it.

johnu Posted March 2, 2014 Report Share Posted March 2, 2014 Playing Jeff Rubens' original responses for Kickback GSF, 5♠ is GSF for hearts 1 Step - i.e. 5NT ace or king, but not ace with 3 or more trump than expected 2 Steps - i.e 6[clubs] queen and/or 2 more trump than expected, or 3 or more trump than expected 3 Steps - i.e 6[diamonds] No trump honor but 1 more trump than expected 6 of trump suit - i.e. 6[hearts] No trump honor and expected length higher (6NT or other to try for 7NT) 2 of the top 3 or ace with 3 or more trump than expected Your response would be 6♣. Since you showed 4 or more hearts in the bidding, this could be queen, or 6+ trumps which is almost impossible on this auction. These methods give you a chance to safely bid a grand with 12 trumps missing the king, or 10 or 11 trumps missing the queen. Quote Link to comment Share on other sites More sharing options...

gszes Posted March 2, 2014 Report Share Posted March 2, 2014 Whatever my agreement is. For me, 6C shows the A or K, 6D the Q and 6H none (6NT 2), so I will bid 6D. The same answer as Siegmund, but from the opposite direction. Partner must be 0580 or similar. While having a hughmongous jump like 5s to show GSF for hearts is ideal; even using5n for all suits can be bid well if you use the above method to save space when youhave a better holding. There is zero practical benefit to showing the Q with your bid (6c) if you use 6c to show the A or K partner will (on rare occasion) be ableto bid 6d asking you to bid 6h with the K and anything else with the A. 6n toshow 2 is ok if it promises two outside aces while a bid of another suit shows that ace (and 2 of the top 3) and denies any other ace and a bid of 7h shows 2 of top 3 and no outside aces:) The 5N as GSF pops up rarely but using a refined agreement like the one proposed by franceshinden is an upgrade that should be a part of every improving players bidding.

Zelandakh Posted March 3, 2014 Report Share Posted March 3, 2014 Frances' scheme looks good to me for the hearts + 5NT case. If we instead use 5♠ as the GSF then one option is bumping these responses down one step (which is effectively what Rubens is doing) while another (posted a couple of years ago) is simply to use a reverse step method: 1st step = 5NT = ace (then 6♣ asks for extra length)2nd step = 6♣ = king (then 6♦ asks for extra length)3rd step = 6♦ = queen4th step = 6♥ = none5th step = 6♠ = KQ6th step = 6NT = AQ Quote Link to comment Share on other sites More sharing options...
