Free Posted May 12, 2005 Report Share Posted May 12, 2005 Why not use fibonaci numbers: 2, 3, 5, 8. B) These already have something to do with relaysystems... Quote Link to comment Share on other sites More sharing options...
keylime Posted May 12, 2005 Report Share Posted May 12, 2005 I use O/S in my p'ship - it is rather a nice system. However, part of O/S's success is understanding the opening leads that go with it, not just 3rd hand play. With regards to the BIL - I don't think that O/S is really for that genre because not only do you have to attempt to condense a whole book but the concept requires the understanding of when to give count and basic s/p strategies. Many folks don't have those needed skills yet. We use 2nd/4th in suits, attitude leads at NT, with MUD and udcasp with rev. s/p lav 1st disc. at suits, straight UD att at NT.

luke warm Posted May 12, 2005 Report Share Posted May 12, 2005 Why not use fibonaci numbers: 2, 3, 5, 8. ;) These already have something to do with relaysystems...hmmm... how bout encrypting them? say partner leads an ace... how do you signal your suit preference? find the nearest lucas number (11)... identify the numbers surrounding it (7 and 18)... multiply those by one another, square the 11, and subtract (you don't have to actually do this, it's always 5) ... if the led card is >5, subtract the two (the ace would obviously be 13, etc)... if the answer is odd, partner is calling for the lowest non-trump.. if even, the highest... if the led card is <5, add the two... now an odd result calls for a red suit, even for a black suit or, you could just play standard carding Quote Link to comment Share on other sites More sharing options...
Winstonm Posted May 13, 2005 Report Share Posted May 13, 2005 I believe in playing the most complex carding system I can devise in combination with the dumbest partner I can find - that way if anything goes wrong I can point out his hideous error and he can't prove me wrong. :) Quote Link to comment Share on other sites More sharing options...
Al_U_Card Posted May 18, 2005 Report Share Posted May 18, 2005 Like all systemic agreements, a little knowledge can be a dangerous thing. The classic attitude signal to pard's lead is whether or not he should continue the suit. OS stipulates that if you discourage the lead, you are happy with a switch to the weakest (non-trump) suit in dummy. Kxx is weaker than JTxx etc. Via con dios :unsure: Quote Link to comment Share on other sites More sharing options...

It is well within the scope of a regular partnership, it simply needs to be studied and practiced. Quote Link to comment Share on other sites More sharing options...

It always worked fabulously and wasn't hard to apply in 95% of the cases. Would use it anytime with anyone, but got tired of explaining it to pick-up pards, so......

whereagles Posted May 20, 2005 Report Share Posted May 20, 2005 Well, one must be careful not to follow the Granovetters' solutions too close. I once did that when playing "obvious shift" methods and handed over a slam due to lack of count signals. Quote Link to comment Share on other sites More sharing options...
Gerben42 Posted May 20, 2005 Report Share Posted May 20, 2005 Well you need to know when to use it and when not. I have found OS and frequent suit preference work great for me. I can recommend it to everyone with sufficient experience to do something useful with it. But: Suit preferencel is one of the most complicated things there is in bridge. Use it wisely.

mike777 Posted May 20, 2005 Author Report Share Posted May 20, 2005 Well, one must be careful not to follow the Granovetters' solutions too close. I once did that when playing "obvious shift" methods and handed over a slam due to lack of count signals. Agree nothing works 100% of time but if you can remember hand and post, thanks. Count is very rare, here are some exceptions. "Suit-preference signal can be used for length, to help partner keep the right suit in the endgame(eg., versus 7nt, following up the line in a suit led by dummy or declarer may signify more length in a lower ranking suit than in a higher ranking suit.) Exceptions to the OS signal at trick one.1. Versus notrump, if dummy wins the trick holding QJX or JTX we give count if we have no high honors in any suit at all. (Partner with al lthe strength will guess it is count).2. Versus as slam, on the lead of an A-K we give count.3. Versus the five level, when we are known to hold 5 cards or more in the suit led, we add to our Attitude/OS signal a count card by playing an odd card for an odd number or an even card for an even number. For example, odd-high=odd number, encouraging." Quote Link to comment Share on other sites More sharing options...

I don't remember the hand, but the situation was simple. Opps were playing 6NT after an unrevealing auction. At some stage I needed to make a discard, and from the play of the cards, declarer had either a 4333 or a 4234. I couldn't tell which because me and pard were playing "suit preference all the way", so no count. I discarded hoping for a 4234 because that shape was more likely than the 4333. Wrong choice... lol.

Maybe this was a case where suit pref should have shown length as in the 7nt example, hard to tell, oh well. Quote Link to comment Share on other sites More sharing options...
Al_U_Card Posted May 20, 2005 Report Share Posted May 20, 2005 Interesting. I mostly found that once the initial suit preference signal was given that 99% of the issues were resolved and std signalling worked fine. I once kibbed a match between Molson/Baran vs Passel/Lair and they never seemed to give obvious count signals. Not something I could reasonably aspire to I'm afraid.

Double ! Posted May 22, 2005 Report Share Posted May 22, 2005 I suggest that one read the Eric Rodwell Interview posted at the Bridge Matters web page, particularly with regards to signalling.IMO, pick the method that you are most comfortable with (that comes most naturally or instinctively to you) and go from there. More importantly: COUNT! like, count to 13!!!!! Quote Link to comment Share on other sites More sharing options...
fifee Posted May 31, 2005 Report Share Posted May 31, 2005 Bobby Goldman and Paul Soloway who played together for 20 years used standard carding with very little count. Their first priority was to show smith echo by either defender if it was not obvious whether they "liked" the lead or not. They would play an unecessarily high card at the first opportunity when following suit asap to say, "Yes, I liked your lead or my lead." They used smith versus all contracts, too, not just NT. Suit preference was a big part of their defense, as well, whenever they could. Bobby always said there is no carding technique that beats thinking at the table though.
