And if partner is long in spades, and if he's got good first-round control, and if he trusts you to understand what he's doing the two of you may go into a round of cue bidding -- if you've got the right voids you could go to slam (and it's such a crime to bid game and make slam). -- Tim Wescott Wescott Design Services http://www.wescottdesign.com

Hi Al, Look up "Jacobi transfer". He would bid 4 hearts as a tranfer to 4 spades. You want the strong hand playing the contract for several reasons. -jim -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =-----

You suggested a completely bust hand, with a void I might play it differently. We also didn't establish the surrounding game conditions. In duplicate, you might bid differently depending on your overall position. -- Al Clark Danville Signal Processing, Inc. -------------------------------------------------------------------- comp.dsp conference July 28 - Aug 1, 2004 details at http://www.danvillesignal.com/index.php?id=compdsp email: compdsp@danvillesignal.com Who says you can't teach an old dog a new DSP trick?

Jim, I know what a Jacoby transfer is but I have never actually played with anyone that used it. I read too many bridge columns in the newspaper. I think the response would be 3 hearts for Jacoby. I agree that in most cases the strong hand should play the hand but I'm not sure that we will find 4 spades which I think is the place to play these hands. If you bid three hearts, many players will pass since you are generally promising squat. I think that the weak hand will still make 4 spades even with the strong hand in dummy and I doubt there is a slam available. in rubber bridge, this is an easy decision since overtricks don't mean much. In duplicate, we probably have stronger players and we certainly would have established if we play Jacoby, Stayman, etc. Moving on to the joys of convolution..... -- Al Clark Danville Signal Processing, Inc. -------------------------------------------------------------------- comp.dsp conference July 28 - Aug 1, 2004 details at http://www.danvillesignal.com/index.php?id=compdsp email: compdsp@danvillesignal.com Who says you can't teach an old dog a new DSP trick?

Yeah, your right 3 hearts would be the classic Jacoby transfer. A bid of 4 hearts is a refinement of the convention also known as "Texas transfer" .Its designed for just this sort of hand. -jim -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =-----

Is that anything like a Jacobian determinant?

Then the bidding goes 2NT, 3H, 3S, 4S and play (or cue-bid, depending on the 2NT hand, or your partner)

Only once, then you will explain the importance of _never_ passing on a Jacoby to them. Then they'll either understand the importance of recognizing a Jacoby transfer or you'll bury them someplace out of the way. This is probably urban legent but there was supposed to have been a case in the 1920s when bridge was _very_ popular where a couple of husband-wife teams were playing a friendly game of bridge. The host's wife muffed the bidding, and when dummy was laid down the host quietly got up from his chair, went to the bedroom, got his revolver and shot his wife. When the case came to trial the defense team showed the jury the hand and the bidding sequence -- it was ruled justifiable homicide.

Incredibly weak hands can make incredible slams, if the cards are just right. In this case if partner has the top spades and a good fit with the side suits there's a good chance at slam. This is, of course, what cue bids are for. In fact if you're holding seven spades to the 10, your partner has A-Q-K of spades, aces in all the side suits and you have at least one card in the other three then you'll always make a grand slam -- you just take the first trick in partners hand, run trump, transfer to one of partner's remaining 2 aces and take the last trick. There are similar sure-thing plays if you have voids where partner has aces, as long as you can get to partner's hand for the end game.
