The Rubensohl Convention
Review sheet 61UZ-2 10/01/2021 The Rubensohl convention You will use the Rubensohl convention in response to your partner's 1 NT opening, but after an overcall. Here is the simplified theory of this convention. After a natural overcall 2 ♦, 2 ♥ or 2 ♠ Any level 2 bid is natural Above 2 NT any bid is a Jacoby transfer. 2 NT is artificial (Jacoby for ♣) An impossible Jacoby becomes a Stayman A double is a take-out double : it could be a Stayman with 8 HCP, or show a balanced hand with 8 HCP or more.

Review sheet 61UZ-2 10/01/2021 The Rubensohl convention After a natural level 2 overcall Bidding a suit at level 2 is natural and non forcing : the responder holds a maximum of 7 HCP Doubling is not punitive : A double requires a minimum of 7-8 HCP and most of the time shows a hand with which the responder would have bid 2 NT (with no overcall). -
Mirror (“Shadow”) (“Stolen Bid”) Doubles
“Mirror” (“Shadow”) (“Stolen Bid”) Doubles Mirror Doubles are sometimes used by Bridge Partnerships when a Player, poised to respond to Opener‟s strong, (15-17 HCP) 1-NT opening call, is confronted with a 2-level overcall by the would-be- Responder‟s, right-hand Opponent (RHO). Using “Mirror Doubles,” Responder‟s “double” under these circumstances, means, “Partner, my right-hand Opponent (RHO) has just stolen the bid that I was about to make. Had my RHO not done so, I was about to make the same bid that he/she just made.” For example, if a would-be Responder‟s right-hand Opponent overcalls 2D, and Responder “doubles,” it means that Responder was about to transfer to 2H, and so on. Opponent’s Overcall Meaning of the “Mirror Double” 2♣ Stayman 2♦ A Transfer to Hearts 2♥ A Transfer to Spades 2♠ By Partnership Agreement Today, although the use of “Mirror Doubles” remains as a staple of many recreational, local club Bridge Players, they tend not to be used by most of the better Players, with the exception of a “double,” following an interference call of “2C,” which is still, most often, used as a “Stayman” call; i.e., “Systems Are On,” and Opener is asked to respond as if Responder had invoked a Stayman, “2C,” initiating response. Other than this use of a “Mirror Double” over an interference call of “2C,” most of the better Players use a “double,” subsequent to 2-level, interference calls, above “2C,” as a far-more important, Negative or Penalty Double. The consensus seems to be that “Mirror Doubles” over interference calls at “2D” and above come at too high a cost, and that the loss of the ability to use a “double” as a Penalty or Take-Out, is too dear. -

March 2018 ACBL Bridge Bulletin Notes Jeff Kroll Sam Khayatt
March 2018 ACBL Bridge Bulletin Notes Jeff Kroll Sam Khayatt Reisinger BAM Teams (p. 14 – 16) Page 15, column 1, fifth paragraph: When West doesn’t find the killing spade lead, 7C is made by setting up dummy’s diamonds. Declarer realized that both the CK and C7 are needed entries to the diamond suit. Don’t pull trump at tricks two and three. Pull them as you use the K and 7 as transportation to the diamonds. Page 15, column 2, sixth paragraph: the SQ is played by declarer to finesse against the SK. West chose to cover, the correct play. West is trying to set up his S9. When East plays the S7 then shows out, declarer unblocks the S8 to finesse against West’s S9. Gordon, page 32, topic 1: when you alert and are asked to explain, you must give an explanation of the alerted bid. If you end up declaring, you must give an explanation of any undisclosed agreement, and any misinformation given in the auction, before the opening lead. On defense, you must wait until after the deal to divulge any misinformation – you can’t clear it up for partner. The Bidding Box (p. 37 – 39) Problem 1 Both Easts appropriately pass after North opens 1S: East… Is not strong enough to double and bid, Cannot make a takeout double with only a doubleton heart double, and Cannot overcall that four- card diamond suit– especially at the two-level. East must pass and count on partner to keep the auction open in the balancing position. -

Points refer to a total value of a hand, including shape. HCP refers only to a hand’s high-card points. A natural suited bid shows 4+ cards in its suit. A natural notrump bid shows a desire to play in notrump. A non-natural bid is called an artificial bid. A convention is a commonly used artificial bid that has been given a name. Conventions are not part of Standard American, but many are commonly or nearly-universally played. A forcing bid demands a bid from partner if the next opponent passes. A forcing bid is also known as one- round-forcing. A signoff is a bid that strongly requests a pass or correction to another suit shown by the player signing off. Partner normally may not make a bid in any suit not shown by the signing-off player. A signoff usually occurs when the captain of the auction places the final contract. An invitational bid communicates that the partnership should bid a game unless partner has very minimal strength for previous actions. A game-forcing bid means that the partnership cannot play any contract below 3NT. -

Jacoby Transfers Acoby Transfers Are a Very Popu- Lar Treatment, and with Good Jreason
Jacoby transfers acoby transfers are a very popu- lar treatment, and with good Jreason. They’re easy to play, and they help describe common types of PLAY BRIDGE PLAY hand patterns in response to a 1NT opening. For the purposes of this article, we will assume that 1NT is strong (15 to 17 high-card points), but Jacoby transfers may be used with other notrump ranges as well. After a 1NT opening, responder may use a Jacoby transfer to de- scribe a hand with a five-card or this table provides a general guide- K Q 6 5 3 5 A J 7 2 Q 9 4. longer major.

The Foundation System
The Foundation System Notrump Bidding Introduction This chapter treats hands in which Opener holds a balanced hand (4333, 4432, 5332 with a 5-card minor, perhaps occasionally 5422 or 6322 with a 6-card minor or 5332 with a weak 5-card major) of three different strength ranges: 15-17 HCP (1NT opening), 20-21 HCP (2NT opening), or 22+ HCP (2C opening followed by a 2NT rebid by Opener). Other strength ranges are treated in the chapter on Minor Suit Bidding: 12-14 HCP (1C or 1D followed by a 1NT rebid by Opener) and 18-19 HCP (1C or 1D followed by a 2NT rebid). A 5-card major is acceptable for the stronger openings (2NT and 2C then 2NT). These strength ranges are not absolute. A bad 15 HCP can always be downgraded to open 1C or 1D; a bad 18 HCP can be downgraded to open 1NT; and a bad 22 HCP can be opened 2NT. The Bridge World magazine maintains a system called Bridge World Standard which is based on the preferences of a panel of experts; their notrump ranges are expressed as a good 15 to a bad 18, and a good 20 to a bad 22. Further discussion of such adjustments will be deferred until the Bidding Practice quizzes in Part II. Responses to 1NT Note: Unless otherwise noted in the discussion, these same responses and rebids apply, but obviously one level higher, after a 2NT opening , and also after 2C/P/2any/P/2NT (so long as the 2any response is artificial and does not show any specific suit).
