This document provides lessons on bridge bidding conventions, including: 1) Game tries/slam tries over 1M openers, where opener rebids the next cheapest suit to check for a game or asks for shortness with the cheapest suit to check for a slam. 2) Two schools of thought on jumpshifts - strong jumpshifts showing a game force or weak jumpshifts to play with a balanced hand. 3) Splinter bids showing a singleton in the bid suit and support for opener's original suit. 4) Two-way Drury convention where a response of the next suit shows either 3-card support and 10-12 points or 4+ card support and 10-12 points

Lesson 11Game Tries/Slam Tries over 1M Openers
RevisionSo far, weve learnt that you may respond to 1M openers with 2X, 1S (in the case of 1H openers), xNT or xS.2S = 6-9 points, 3+ card support3S = 10-12 points, 3+ card support4S = 13+ points, 3+ card support1NT = 6-9 points, no spade fit2NT = 10-12 points, no spade fit3NT = 13+ points, no spade fit1S (over 1H) = 4+ spades, 6+ points2X = 5+ cards in X, 10+ points
Game Tries after 1M-2MWhat does opener do if opener has a strong hand (15+ to 18- points) and wants to check if game is available?Opener rebids the next cheapest bid i.e. 1H-2H-2S or 1S-2S-2NTResponder rebids the cheapest suit in which he has a feature (one of the top 3 royals at least)Opener then decides whether there is a secondary fit which may produce extra tricks and decide on the contract accordinglyAfter 1H-2H-2S, responder bids 2NT to show a spade feature
Slam Tries after 1M-3MOpener rebids the cheapest suit (Mathe asking bid) as a slam try i.e. 1H-3H-3S or 1S-3S-3NT to ask for shortnessWithout shortness, responder bids 4M to end the auctionWith shortness, responder bids the suit in which he is short at the 4th level
Jumpshifts Two Schools of ThoughtA jumpshift is defined as a bid that is one level higher than the lowest level possible for that suitE.g. 1H-2SE.g. 1C-2HE.g. 1S-3DSchool of thought 1: strong jumpshiftsSchool of thought 2: weak jumpshifts
School of Thought 1: Strong JumpshiftsThis is more commonly used with Standard American Yellow Carding (what we have been learning so far)This school of thought uses strong jumpshifts as a game-forcing bid and showing 5+ cards in the suit bid
School of Thought 2: Weak JumpshiftsThis is more commonly used with 2/1Because there is no longer a need to jumpshift to GF in 2/1, weak jumpshifts are used instead2nd level weak jumpshifts show 2-5 points and 6+ cards in the suit bid3rd level weak jumpshifts show slightly more, probably 5-9 points and 6+ cards in the suit bidWeak jumpshifts are to play and opener is generally recommended to pass
Splinter BidsRight now, 1M-4X is a useless bid so wed might as well put it to use1M-4X a splinter bid showing 4+ card support for M and a singleton/void in X, 12+ pointsE.g. 1S-4C shows 4+ spades and singleton/void in XException: 1H-3S is also a splinter bid. It doesnt make sense for 1H-4S to be the splinter bid as it forces a contract at the 5th or higher level
2-Way DruryIf you pass with 10-12 points and your partner opens on the 3rd seat with 1M (a suit in which youre long too), your partnership may have a game anywayWe have thus come up with the 2-Way Drury bid1M-2C shows 3 card support and 10-12 pointsOpener can rebid 2D to show he couldve opened by rule of 20Opener can rebid 2M to show he opened by rule of 18 so the partnership can sign off at that level1M-2D shows 4+ card support and 10-12 pointsOpener can no longer show a less than opening hand, but has knowledge of an extra trump and can better decide where the contract should be2M on top of 2D is sign-off, 3M is invitational. Responder only bids up to game with favourable distribution
2-Way DruryOpener may also bid 2H on top of 1S-2m to show a 4-card heart suit. This promises opening strengthOpener may also bid 3m on top of 1M-2m to show a 5-card minor and responder can then decide where to place the contractIf responder wants to show a good minor suit instead, responder should bid 3m instead of 2m
