PRO* 1.41 (Meanness index) The Pattern Relay Organized system is an American system based on a 1C opening showing a balanced hand or clubs, and a complete relay structure in the subsequent bidding. Information from Kearse, Bridge Conventions Complete. PRO Opening Bids 1C 12-20 3+ clubs 17-20 balanced 1D 12-20 3+ diamonds 1H 12-20 5+ hearts 1S 12-20 5+ spades 1N 14-16 balanced 2C 21+ 5+ clubs 2D 21+ 5+ diamonds 2H 21+ 5+ hearts 2S 21+ 5+ spades 2N 21-22 balanced http://bridgewithdan.com/systems/bridge-system-collection.txt PRO-System or Pattern Relay Organized This is a bidding system previously played by many partnerships on the West Coast of the United States. 1. Intermediate No Trump openings: 14-16 high card points. 2. Forcing 1 Club openings a. Promises either a long Club suit with opening values or b. Balanced holding with 17-20 high card points. 3. Non-Forcing Two-over-One responses and Jump Shifts. 4. 4-card Major suit openings a. any 1 No Trump response is game-forcing. 5. Reverse Bids based on distribution rather than strength. http://www.bridgeguys.com/PGlossary/GlossP.html

Interesting, similar to Larry Weiss's Simplified Club. By now you probably know about M.I.C.S. by Rexford: http://cuebiddingatbridge.blogspot.com/2010/03/modified-italian-canape-system.html Also, Sabine Auken's system, I Love This Game, has canape overtones which we have adapted for our Strong Club System: http://bridgewithdan.com/systems/Ultra.pdf The next version C3: Copious Canape Club is still in test mode (2 years now). Waiting for details on Pattern Precision for possible new ideas ....... Finally, a 1993 book: Hand Pattern System, by A. V. Delmain: 1 ♣ = 16 + hcp with natural positives & impossible negative 1♦ = 7 losers or less and both minors (5-4 or better) or a single suited hand (any suit) 1♥ = 4 or more hearts and 5-4 or better distribution with diamonds 1♠ = 4 or more spades and 5-4 or better distribution with diamonds & spades, 7-losers or less 1NT = 13-15 HCP 2♣ = Clubs and a Major, 5-4 or better either suit longer, 7 or less losers 2♦ = 4441 and 7 losers or less 2♥ = 5-4 with the majors, hearts longer, 7 or less losers 2♠ = 5-4 with the majors or better, spades longer, 7 or less losers 2NT = 5-5 in the minors, unlimited strength. 3 NT = 6-5 in the minors with AK in one minor and K or better in the other minor

I pass and look for a new partner.

I play Keri over weak NT with two partners (over 2 years now) and find it reasonable at MPs or IMPs. We tend not to open 1NT with extreme distribution, but do include weak 5-card majors. Here is a reference to revised Keri: http://www.bridgebase.com/forums/topic/5553-revised-keri/ P.S. Hi Steel Wheel.

Your calculations for 9 - 13 card suits agree very well with my reference. For 0 - 7 card suits I find poor agreement. (Before electronic calculators I had calculated the HCP frequencies and found exact agreement with the authors.)

From bridge odds complete, by Frost, Kibler, Telfer, and Traub, 2nd edition, 1971: f(x) 8-cards (exactly) = 0.117% (Specific suit, one player); 0.47% (One player, any suit); 1.87% (The Deal, any suit) And, 8+ cards = 1.87 + 0.148 + 0.0066 + 0.00015 = 2.025 % (8 or more cards in a suit).

Very nice! A later question in these postings: What is the probability of having Three 8-card suits in 36 deals???

Read the postings, it has been done already. 0.42% if you ignore 8-4 and 8-5 variations

8221 / 8311 / 8320: f(x) = 0.42% or 4.2 times in 1000 hands for only one 8-card suit. f(x) 3 times = (0.0042)**3 = 73 / 10**9 or 7.3 times in 100,000,000 hands which is highly suspect. [Edited 11/1: This calculation is for being dealt three 8-card suits in 3 deals in a row.] Is this within 3 sigmas of the mean? We can't calculate the range without knowing the variance of the program.

1. Not ACBL legal in GCC events (unless LHO of the opener Doubles). 2. One approach is to use X to show the suit bid and bid the suit promised as a takeout for the other two or three suits. 3. It depends if you have players that use the GCC legal transfers: It is GCC legal to use transfers after a takeout double or in responding to a takeout double. Also, if your partner overcalls, you can use transfer advances.

The most outstanding example were three 8-card suits in 36 hands (x4) in one game in September. Most of the boards in our largest game (15 - 18) tables were hand dealt 5 - 7 times before we started using Deal Master Pro.

I play this style (raising to game as pre-emptive or expect to make game) with several partners especially playing match point pairs. However, in IMP competition I revert to Hardy Raises with possible slam invitational hands. However, playing canape we use 2♣ as an Artificial and Game Forcing relay with 3-card or less support while still using 2NT as 4-card invitational or better support.

Session 3 and 4 were the biggest losts. http://www.worldbridge1.org/tourn/Veldhoven.11/Microsite/Results/BoardDetailsKO.asp?qmatchid=4341&qphase=FF http://www.worldbridge1.org/tourn/Veldhoven.11/Microsite/Results/BoardDetailsKO.asp?qmatchid=4342&qphase=FF

Cold after the A♦? Hmm, just duck the A♣ later in the hand and declarer has 4 losers. Oh, you must mean it is cold if he finesses the 10♠.

True, but my partner is a math major and I am a statistics minor and both of us are suspicious of the non-randomness of the 2340 hands so far.

I would adjust this very good scheme to approach what Keylime and I play: 1♥ = 4+ ♠ and 8+ hcp, G.F., OR 11-14 hcp & balanced (rebid 1NT over 1♠ relay) 1♠ = 4+ ♥ and 8+ hcp, G.F. 1NT = Majors (5-4 or better) & 8 hcp or 4441 with a minor suit singleton & 11+ hcp 2♣ = one or both minors and 8+ hcp (no 4-cd major) 2♦ = 8-10 hcp & balanced (Rodwell's best idea) 2♥ = Choose one: 5♥332 / 6♥322, or 3-suited, 4441 and 11+ hcp 2♠ = Chose one: 5♠332 / 6♠322, or 3-suited, 5440 with a 5-cd minor 2NT = 15+ hcp

After 90 days and 60 deals and 2340 hands, most players are not convinced that this program approaches statistical norms. Thanks for the reply.

Our Tennessee Club in July started using pre-dealt hands using Deal Master Pro software. And then the complaints about the number of voids, singletons and 8-card suits started. Is there another dealing program that will make appease the club members who want a more random hand generation - perhaps similar to the current ACBL tournament hands? Larry

Try this URL: http://bridgewithdan.com/systems/Fantoni_Nunes.txt or their convention card and notes: http://www.ecatsbridge.com/documents/files/ConventionCards/2009BermudaBowlBrazil/bermudabowl/italy/fantoni-nunes.pdf

Yes, starting the auction at 2NT is known to be a slam killer, especially for minor suits even playing Standard or 2/1 G.F., or Precision with a 2NT response showing 14+. Put the balanced 11+ hands into the 1♥ response to a strong 1♣ opener: 1♥ = (a) 5+♠, or (b) Balanced 11+. 1♠ is the follow-on and responder rebids 1NT if balanced and 11+ and other bids show 5+♥ or a second suit, 2NT rebid would be 5332. Over 1NT, 2♣ by opener is Transfer Stayman. You can invent your own follow-ons to show 11-14 or maybe 2NT or higher showing 15+ hcp.

With my Tournament Partner (Keylime) I play Our version of Transfer Precision modeled somewhat on Sabine Auken's system: Responses to 1♣: 1♦ = 0-7 hcp The following responses are ALL G.F. 8+ hcp with an Ace or King 1♥ = (a) 4+♠,or (b) 11-14 balanced 1♠ = 4+♥ 1NT = Majors: 5-4 or better, or 4=4=1=4 / 4=4=4=1 and 11+ hcp 2♣ = 1 or both minors and NO 4-cd M 2♦ = 8-10 hcp balanced a la Meckwell 2♥ = 5♥332 with good hearts, or 6322 with weak hearts: Jxxxxx or worse. 2♠ = 5♠332 with good spades, or 6322 with weak spades: Jxxxxx or worse. 2NT = 15+ hcp, forcing to 4NT 3♣ = 4=4=4=1 or 4=4=1=4 and 8-10 hcp 3♦ = 4=1=4=4 and 8-10 hcp 3♥ = 1=4=4=4 and 8-10 hcp 3♠ = AKQxxx in unknown suit with No extra A / K 3NT = AKQxxxx in unknown suit w / wo extra A / K

With one partner I play our version of Millennium Club (15+ hcp usually balanced, sometimes clubs primary, rarely very, very strong): Responses to 1♣: 1♦ = 4+♥ & 0-8 hcp 1♥ = 4+ ♠ & 0-8 hcp 1♠ = rest and 0-8 hcp 1NT = G.F. with the majors 5-4 or better, or 4414 / 4441 2♣ = G.F. asking if balanced, (2♦) and up are transfer Positives. Edited: last line added: 8/27/16

Yes, I have been using this structure for years and found it to be simple and useful. Use the acceptance of the transfer as a Beta Ask and you will find out at the 3-level if you have enough controls for slam. A raise to 5M after the Beta Reply asks if anything extra (Q?). However, one option is to use 1♣ - 2♦ as the 8-10 balanced thus making 1NT reply 11-14 (too many 14 hcp hands do NOT make slam). Another option is to use 1♣ - 2♣ as ♣ or 8-10 balanced. 2♦ asks and 2M or 2NT shows the balanced hand.
