Davis - Department Computer Science The following hand was published by Krysztof Martens in Przeglad Brydzowy, 1/92. Since it took me some time and has a neat solution, I thought I would pass it on: S: K 8 7 2 S: A Q T 9 H: A 4 H: K J 8 2 D: Q 6 4 D: A K T 9 C: A K Q J C: 6 Give a line guaranteed to make 7NT by West on the club 10 lead. Answer follows. If you haven't solved it yet you can save it for later or give up now. Answer: Play AKQJ of clubs throwing hearts! King of hearts, A,K,Q of diamonds.The position is now: S: K 8 7 2 S: A Q T 9 H: A H: - D: _ D: T If the diamond ten is high, claim, otherwise play the heart ace throwing the diamond 10. If the diamond jack is still out, play the other hand for 4 spades. If someone shows out on the heart ace, you have a complete count. ------------------------------------------------------------------------- ----- BRIDGE USENET appended at 16:19:34 on 91/06/13 GMT (by USENET at ALMADEN) Subject: Strong Club or Pass defense From: bs@faron.mitre.org (Robert D. Silverman) Message-ID: <1991Jun13.140700.16999@linus.mitre.org> Date: 13 Jun 91 14:07:00 GMT I am presenting a systemic defense to strong 1C, 2C or strong pass systems. It is named after a former partner of mine (now a regional director). It also has some elements taken from a defensive overcall system called Active Defensive Overcalls, invented by Kris Bhavnani. Kris is a New-England area expert player who also has a national reputation as a bidding theorist. Caveat: DO NOT PLAY THIS WITHOUT A LOT OF PRACTICE & DISCUSSION WITH PARTNER. It has many consequences and takes work to memorize. Here's the Bjorge convention in a nutshell. After a strong 1C or 2C or pass opening a suit overcall AT ANY LEVEL is a relay to the next higher suit. The overcaller can have one of three types of hands: (1) A 1-suiter in the suit to which he relays (essentially a transfer overcall) (2) A 3 suiter with shortness in the suit to which he relays. (5440 or 4441) (3) A touching two suiter EXCLUDING the suit actually mentioned (not excluding the suit to which you relay) Every two suiter can be shown in two different ways to emphasize one of the two suits as being 'better'. [longer or stronger] If one of the two suits is the relay suit, then that is the 'better' suit. Otherwise, the suit just below the bid suit is the better suit. The system uses a PASS to show a strong balanced hand [t/o double] and has exclusion responses from partner. It uses Dble and 1NT as light takeout bids depending on the spade suit. Clubs are considered to be the suit above spades. Here is the system: After 1C Suit bid at any level or 1C P 1D Suit at any level or Strong Pass Suit bid at any level We will call the suit bid X. X asks partner to relay to the next higher suit. (Y) The bidder of X then bids as follows: 1st available step : Y is short. I have 4x1 or 5440 2nd available step : 2 Suiter - the two suits BELOW X. 3rd step : 2 Suiter - the suit just below and the suit just above X 4th step : 2 Suiter - the two suits ABOVE X 5th step or Pass : 1 suiter. I have suit Y. Responder, with a good suit of his own is NOT obligated to accept the relay. He can bid his suit. This system is NOT meant to be CONSTRUCTIVE. For example. 1C 1H(1) P 1S(2) P 1NT (1st step) shows short spades 2C shows the minors (2 suits BELOW hearts) (better diamonds) 2D shows diamonds and spades (suit below & suit above hearts) (better spades) 2H shows spades and clube (2 suits above hearts) (better spades) P or 2S shows spades Here's a complete table: If the overcall suit was: Then: diamonds. spade rebid = short hearts NT rebid = spades & clubs (better clubs) club rebid = clubs & hearts (better hearts) diamond rebid = majors (better hearts) pass or heart raise = hearts hearts. NT rebid = short spades club rebid = minors (better diamonds) diamond rebid = diamonds & spades (better S) heart rebid = spades & clubs (better S) pass or raise = spades spades (relays to clubs) diamond rebid = short clubs heart rebid = hearts & clubs (better clubs) spade rebid = minors (better clubs) NT rebid = red suits (better hearts) raise or pass = clubs clubs heart rebid = short diamonds spade rebid = majors (better spades) NT rebid = spades & diamonds (better D) club rebid = red suits (better D) pass or raise = diamonds. A Dble of either 1C directly, or 1C P 1D is a light takeout bid with exactly 4 spades and 6-12 HCP. It shows a balanced hand: 4x3 or 4432 with 4 spades. A 1NT overcall of either 1C or 1C P 1D is light takeout with 2 or 3 spades. Over either of these bids, responder bids naturally. If the NT overcall is doubled, a redouble shows exactly 4 hearts. A PASS over 1C shows a balanced hand of 13+ HCP if NON-VUL. It says nothing if VUL. It is 4432 or 4333. It is similar to a power double. Responder makes an EXCLUSION response. That is, a non-jump bid by responder shows the suit responder DOES NOT want to play in. [shortness!]. A NT bid by responder says he has 2 short suits [or alternately at least a 5422 hand] A PASS by responder says he is 4333. A jump by responder is natural and preemptive. A double by responder, e.g. 1C P 1D Dble, says responder is 4333 and has cards [at least 6 HCP]. -- Bob Silverman #include Mitre Corporation, Bedford, MA 01730 "You can lead a horse's ass to knowledge, but you can't make him think" In the interests of keeping commercial stuff off of this group we have generally been replying by e-mail, but as there have been a number of requests for OKbridge info recently, I'm going to post this. Warning! Information about a commercial product follows! ------------------------------------------------------------------------- We have a WWW page at http://www.cts.com/~clegg/ which contains lots of useful info about OKbridge and other bridge resources on the Internet. You should be able to get OKbridge by entering the following command at the Unix prompt on the host from which you want to play bridge: telnet 199.33.217.1 5332 | csh This will execute a script which downloads the source to your machine and compiles it, resulting in a program called "okbridge2" which allows you to play OKbridge. Precompiled binaries for a number of machines can be downloaded from crash.cts.com (192.188.72.17) in /pub/okbridge/binaries by anonymous ftp. You will also need the okbridge2.help file if you install the binary. OKbridge2.0B is not "alpha" nor "beta" software, it is a stable commercial release. It will write an .ok2defaults file which will keep track of your password for you and log you in automatically (I can't remember my password either...) Direct inquiries to info@okbridge.com Anyone outraged by this post, please reply to me directly David DeMers Dave@okbridge.com ------------------------------------------------------------------------- 1. If it could be natural, it is natural. 2. If the hand that makes the bid has not limited itself, the ambiguous bid is forcing; if the bidder is limited, it is NF. 3. Finding the right game always takes precedence over exploring slam possibilities.
