Cambridge University Bridge Club Beginners Lessons 2006 Lesson 2. The basics of Acol 1NT opening Jonathan Cairns, jmc200@cam.ac.uk Introduction Last week we learnt Minibridge - a simplified version of Bridge with no auction. We learnt: that a contract is a declaration to take a certain number of tricks how to use High Card Points (HCP) to pick the contract level. card-play and how to make tricks. Tricks Contract Level Points required (HCP) 13 7 7 7 7 7NT Grand Slam About 37 12 6 6 6 6 6NT Small Slam About 33 11 5 5 5 5 5NT 10 4 4 4 4 4NT 9 3 3 3 3 3NT 8 2 2 2 2 2NT 7 1 1 1 1 1NT Game About 27 ( / ) About 25 ( / /NT) Part-score Under 25 Contracts: A summary of what we learnt last week This week, we will start playing Bridge for real! In Bridge, we decide the contract by an auction. Then we play the contract, as we did last week. The reason for making each bid is far more important than knowing what bid to make (which comes with practice), so we will focus on this above all else. We will discuss guidelines on how to bid, but when making a decision, common sense should always come first. From now on, some material that I include in the notes (but will not cover in the lessons) will be surrounded by dotted lines. I suggest you ignore these optional sections for now, but if you're feeling confident, give them a read. Most of the optional material will be concerned with choice of Game between 3NT and 5C/D, and Slam bidding. Page 1 of 8
The Auction Just like any other auction, an auction is a series of bids to try to buy the contract. Starting with the dealer and going clockwise, each player can pass, or bid. 1 A bid states which contract you think you can make (so a bid of 2H says "I expect to make the contract 2H; i.e. I think I can make 8 tricks in hearts"). The first bid (i.e. the first non-pass) is called the opening bid. (That player is said to have opened.) After somebody has opened, bids must be higher than all previous bids. Either: o It must be at a higher level Bids 7 7 7 7 7NT 6 6 6 6 6NT 5 5 5 5 5NT 4 4 4 4 4NT 3 3 3 3 3NT 2 2 2 2 2NT 1 1 1 1 1NT Each bid corresponds to a contract. o OR it must be of a higher strain (choice of trump suit). The suits rank in alphabetical order from lowest to highest: < < < (Clubs < Diamonds < Hearts < Spades). NT beats all of the suits. The bidding continues until three passes are made in a row. The final bid then becomes the contract, and we move into card-play. The person who made the final bid becomes declarer, unless their partner bid that strain first - in which case, their partner declares! If all four players pass without opening, this is called passing out - the bidding ends, the cards are reshuffled and we deal a new hand. Example bid: 7 7 7 7 7NT 6 6 6 6 6NT 5 5 5 5 5NT 4 4 4 4 4NT 3 3 3 3 3NT 2 2 2 2 2NT 1 1 1 1 1NT 4 beats all 1-, 2-, or 3-level bids. It also beats 4 and 4, but not 4 or 4NT. Example auctions: N E S W 1 2 Pass 3 Pass 3 Pass 3NT Pass Pass Pass - West declares 3NT. N E S W 1 Pass 2 Pass 2 Pass 3 Pass Pass Pass - - North declares 3 (North bid first!). 1 You can also "double" an opponent's bid, or "redouble" if an opponent doubles. We will discuss this later. Page 2 of 8
Ending the Auction Once the Auction ends, somebody will have won the contract. That person declares. Their partner becomes dummy - don't put dummy's cards down yet! The person on declarer's left makes the opening lead, as before, but without being able to see dummy. Dummy's cards are placed on the table AFTER the opening lead has been made. As before, we play through all of the tricks, work out whether Declarer has made the contract, and calculate the score. You now know the basic rules of bridge! Give yourself a pat on the back. The Acol Bidding System Last week, when playing Minibridge, we were able to look at all of our partnership's 26 cards before deciding the contract. We looked at suit lengths and counted HCP, to pick the best contract. You no longer have this luxury - now you must try to get to the right contract with only 13 of these 26 cards visible to you! Can we work out what's in partner's hand? Unfortunately, it is considered cheating to lean over the table and ask your partner what cards they have, communicate in sign-language, or kick under the table in Morse code. 2 However, you can communicate with your partner through the bids you make. You'll need to co-operate with your partner, and try to get to the right contract. A bidding system is a series of agreements between you and your partner, where bids are assigned meanings, such as: telling partner how many HCP you have. telling partner how many cards you have in a given suit. asking partner for information about their hand. telling partner what the final contract should be ("signing off"). In this series of lessons, we will learn about the bidding system Acol with three weak twos. Different people play different systems - so be sure to discuss your system with a new partner before playing, to avoid arguments! Bidding Philosophy In most sensible bidding systems, the rule of thumb is that you need 12 HCP or more to open 3 - your hand will therefore need to be reasonably above average. Otherwise, pass. (But what should you open? We will look at this in more detail later!) 2 Sadly, teams have tried cheating with each of these methods in important international competitions. I would not suggest that you copy their behaviour! (see http://terencereese.tripod.com/scandals.htm) 3 But, as always, there are exceptions to this "rule". You can open with fewer points as long as you have a long suit to make up for it. This is called pre-empting, and we will discuss it in lesson 5. Page 3 of 8
Suppose your partner opens. Let's assume that the opponents pass throughout (this will be the case for the next few lessons). 4 Now that partner has opened, you can make a response to the opening bid. Opener may then make another bid. Bidding goes back and forth until the right contract is reached, at which point you stop bidding and pass. Three bidding concepts are key, and we will keep coming back to them again and again: GAME-FORCING (GF): In some sequences, you may discover that game is on. In this case, you can often make a game-forcing bid - this means that neither of you can pass until reaching a game contract. INVITING: If you think game may be on, provided partner is strong enough, then you can invite game by making an invitational bid. Partner bids game (with a strong hand) or passes (with a weak hand). SIGN-OFF IN A PART SCORE: If your partnership is too weak for game, then sign off in the lowest possible part score - that is, make a bid that partner must pass. Game-forcing auctions When you are in a game-forcing auction, the priorities should be, in order: 1. Play in Game in a major suit (4 /4 ) with an 8 card fit. 2. Play Game in NT (3NT). 3. Play Game in a minor suit (5 /5 ). You need 11 tricks to make 5 /5, rather than 9 tricks to make 3NT, so 3NT is usually much easier! Today we will highlight this process by discussing just one of the 35 possible opening bids: 1 Notrump (1NT). Opening 1NT In Acol, a 1NT opening tells partner that your hand: is balanced. A balanced hand is one with no voids (0-card suits) or singletons (1-card suits), and with at most one doubleton (2-card suits). The lengths of your suits must therefore be 4-3-3-3, 4-4-3-2 or 5-3-3-2. has 12 to 14 HCP 5 Any bid that defines your hand as precisely as this is known as a limit bid. Any player making a limit bid should remain passive for the rest of the auction (i.e. partner is put in control, he/she makes the decisions or asks questions and the limit bidder only responds to those questions). Your partner knows far more information about your hand than you do about theirs (they could have anything!) so is better placed to make the judgement. 4 If you practise bidding, away from the lessons, I suggest that for now you treat overcalling (bidding after the other side has bid) in the same way as opening and pass if your opening bid is not available. We ll cover competitive bidding in week six the priorities of the auction become different! 5 This is known as a "weak NT". Some people play 1NT showing 15 to 17 HCP, known as "strong NT". Page 4 of 8
Responding to 1NT To recap, a bid after your partner has opened the auction is called a response. After partner opens 1NT, you should re-evaluate you hand based on the knowledge you now have. Remember a contract is decided on the combined strengths of two hands, so what you thought was worthless might now be extremely valuable. Start by assessing your point count: 0 10 HCP. You have a maximum combined strength of 24 HCP, which is not enough for Game. You need to stop in the best partscore. You have 2 options: Pass with any hand lacking a 5 card suit. You probably don't have a good trump suit between you. Bid a 5 card (or longer) suit at the 2 level - e.g. with 5 spades, bid 2S. You probably have an 8-card fit, and certainly no worse than a 7-card fit (opener cannot be void or singleton in your suit). Trump control is very useful when combined HCP are poor. This is a sign-off bid - Opener MUST pass and accept your judgement that this is the best partscore. (Don t be afraid to do this with 0 HCP and a weak 5 card suit. It will usually play better than 1NT on those occasions.) 13 18 HCP. Your combined strength is definitely enough for game (25 HCP) but not enough for Slam (< 33 HCP), so you must bid game, or force opener to bid game. Your options are: Bid 3NT on any hand lacking a 5 card or longer suit. It will probably be the best game. This is a sign-off bid - opener should pass it. Bid 4H or 4S with a 6 card or longer suit. You are guaranteed an 8 card fit and this is likely to be the best game. This is also sign-off - opener should pass. Bid 3H or 3S with a 5 card suit an 8 card fit is not guaranteed. This is a game-forcing bid. Opener is forced to bid game, but is left to decide whether 3NT or 4H/S is likely to be best. Opener should: o bid 3NT with only 2 cards in your suit o 4H/S with a good 3 card suit or longer suit (judgement is required with 3 small cards, but bidding 4H/S is usually right) Bid 5C or 5D with a 6 card or longer suit, IF you think this will play better than 3NT (e.g., if you hold a couple of unstopped short suits). Remembering that you need to make 11 tricks for a minor suit Game. You will need to use your judgement! Bid 3C or 3D with a 5 card suit, IF you think 5C or 5D will play better than 3NT will play badly. (Game forcing.) This bid is rare, and probably indicative of a two-suited hand e.g. 4-0-5-5. Page 5 of 8
11 12 HCP. You have enough for game if opener is maximum (14 HCP), but not if minimum (12 HCP). You need more information from partner. Invite opener to bid game by bidding 2NT. Opener will: o Pass with 12 13 HCP. Game values are unlikely so decline the invite and settle for the Partscore. o Sign-off in 3NT with 14 HCP and any 4-3-3-3 or 4-4-3-2 shape or 5-3-3-2 with a 5 card minor. o Bid a 5 card major suit at the 3 level with 14 HCP 6. This is game forcing and accepts the invite to game but asks responder to choose between 3NT and Game in that suit (4H/S). Responder signs-off in 3NT with fewer than 3 cards, or the suit game with 3 or more cards. In the rare cases where responder holds more than 18 HCP, Slam becomes possible. Full details of Slam bidding do not fit here, but in general for responder s hands without long suits: 19 20 HCP. Bid 4NT invites opener to bid 6NT if maximum (14 HCP so guaranteeing a combined 33 HCP) or pass if minimum. 21 22 HCP. Sign-off in 6NT guaranteed 33 HCP for Small Slam, but not the 37 HCP for Grand Slam. 23 24 HCP. Bid 5NT. This is a forcing opener to bid 6NT if minimum and inviting him/her to bid 7NT if maximum (giving combined 37 HCP). 25 28 HCP. Sign-off in 7NT. 37 HCP are guaranteed. With slam forcing hands and 5 card suits, you can also use the forcing 3 C/D/H/S bids and then raise whatever Game opener chooses to Slam. And just to finish Passing your partner s forcing bids or bidding over his/her signoff bids is one of the biggest sins at the Bridge table. Don't do it! Declarer play in Bridge After dummy is faced, you will not have had a chance to inspect his/her cards when deciding the contract, so take some time to consider how you will approach the play. We'll discuss this more in later weeks, but as was described in the Strategy section last week: Start by counting quick tricks. How many extra tricks do you need to make? Which suits are they coming from? Think about getting extra tricks from long suits or from finessing (e.g. lead from a hand opposite AQ, if the K appears, take it with the A, 6 Many people will not open 1NT with a good 5 card major, so this bid is not needed. Page 6 of 8
otherwise play the Q). In a suit contract, think about whether to start by drawing trumps. (this is often the right thing to do!) You can learn a lot about declarer play from looking back over a hand after you have played it! Good players love to chat about the previous hand, and try to work out what they should or shouldn't have done. Practice hands You now have the opportunity to play through some practice hands. I have rigged these hands to make sure that the correct opening bid is always 1NT. You will receive a board that contains pre-dealt hands. Take the cards out of the board. Do not mix the cards up, and do not shuffle the hands together! Play the hand, making sure to keep the hands separate as we did last week. When you have finished a hand, place them back into the board as you received them, so they can be played again. Then, collect the next board. Key Points from Lesson 2 The example of opening 1NT was used to illustrate the decision processes used when bidding and about active and passive roles in an auction. It is these thought processes that are the important lessons to take away since we will be using them when discussing other bids next week. Whilst you will still not be able to bid the majority of hands that are dealt at the Bridge table with any great accuracy, you will at least be able to think what bids could be made (what if you re not balanced, or if you re balanced with more than 14 HCP). If you play any hands between now and next week, I suggest that you play Minibridge initially and, at the end of the hand, think about how you could have bid it if playing Bridge. The most important concepts to remember are: Opening the auction on 12 or more HCP 1NT opening as a limit bid and consequences for who controls the auction Assessment of combined strength of a partnership s hands Sign-off bids Invitational bids Game Forcing bids written by Rob Richardson, 2004; updated by Jonathan Cairns, 2011 Page 7 of 8
Bidding Summary This will now be included at the end of every set of notes and will describe most bidding sequences you can have so far. Bids in (brackets) are to be used with judgement as there may be better bids with some hands. Bids not listed are not used in the system so far. Some abbreviations that appear are (which will be added to each week): cs = card suit, F = forcing, G = Game, bal = balanced, M = major, m = minor, sup = card support, Sl = slam.
