You can combine it with a morning coffee, or an afternoon tea, or you can organise an evening event with perhaps a supper halfway through or at the end of the evening. </font></p> <p align=justify><font size=3> You need at least 8 players (2 tables) to be able to play duplicate bridge. <br> More players can be added, preferably in multiples of 4, each filling an additional table. You can have an odd number of people but this means that one or more players are "sitting out" (not playing) for one round, which can be about half an hour. </font></p> <p align=justify><font size=3> Here is a check list of what you need for each group of 4 players. </font></p> <ol type=I><li><font size=3> <font color=#000099> <b> 1 card table </b> </font> - you can use any table which accommodates 4 people, but it is nicest to use a standard card table.

A good director however should not allow this to happen. <br> Successive rounds can be scored on the same traveller for each board. Just leave one blank space (or draw a horizontal line) between each round of scoring. <br> An advantage of this simple approach is that during a halfway break (for tea or supper) all players can freely chat about the deals they played, as all players have completed the same boards. (In a normal club session, with 24 or more individual boards, played at successive rounds at different tables, this is not possible.)</p> <p align=justify>Alternatively you use a set of say 24 boards. <br> In such case 2, 3 or 4 boards are placed on each table as specified on the movement guides. At the beginning of play all boards are shuffled, dealt and played by the players at the table. <br> After all boards on each table have been played, all players and boards move to their specified tables for the next round. <br> All boards are <b> only shuffled and dealt once </b> (at or before the beginning of play) and remain so until the end of the competition. <br> This requires a bit more attention by the director as from round to round the movements of the various boards may move in and out of play.</p> </font> <p><font size=3> </font> <br> <a name=03> </a></p> <center> <hr> <a name=03> <font size=3> ( </font> </a> <font size=3> <a href=#04> Down </a> - <a href=#02> Up </a> - <a href=#00> Top </a> ) </font> <p></p> </center> <font color=#ff0099 size=+2> DUP 3 - Making your own Duplicate boards </font> <p align=justify><font size=3> You can buy aluminium or plastic duplicate boards or (less sturdy) plastic duplicate wallets from any Contract bridge supplies shop.

During play each pair competes all, or a number of, other pairs. This type of competition is fine when all players are about equally skilled. But if some very strong players pair up together then the end result of the competition may become rather predictable. <br> Alternatively you may pair up the stronger players with the weaker ones, but this may be rather frustrating for the better players. You need to judge this against the character and temperament of the various players you have invited. </font></p> <p align=justify><font size=3> In an <b> individual </b> competition all players compete individually against each other. Each player plays with a different player each round. On the whole this is the preferred arrangement for a social event. all players mix regardless of their skill level. This ultimately benefits the lesser players as they have a chance to play with various better players and through these experiences gradually improve their game. </font> <br> <br> <a name=05> </a></p> <center> <hr> <a name=05> <font size=3> ( </font> </a> <font size=3> <a href=#06> Down </a> - <a href=#04> Up </a> - <a href=#00> Top </a> ) </font> <p></p> </center> <font color=#ff0099 size=+2> DUP 5 - Mitchell movements for Pairs </font> <p align=justify><font size=3> There are two common movements for Pairs competition, <b> Mitchell movements </b> and <b> Howell movements </b> . The Mitchell movement is the simplest of the two. It is commonly used for competitions of 8 or more tables, but can be used for 5, 6 or 7 tables too. </font></p> <p align=justify><font size=3> The <b> Mitchell movement </b> works like this. </font></p> <ol><font size=3> <font color=#000099> <li>All <b> NS </b> pairs remain stationary all rounds. <br> <br></li> <li>After each round all <b> EW </b> pairs move <b> up one table </b> . <br> <br></li> <li>After each round all <b> boards </b> move <b> down one table </b> . <br> <br></li> </font> <li><font color=#000099> With an <b> even </b> number of tables only (6, 8, 10) <br> All <b> EW </b> pairs <b> skip one table </b> at the half way point of the movement (at Round 4 with 6 tables, at Round 5 with 8 tables, etc.). </font></li> </font></ol> <font size=3> <br> With an <b> odd number </b> of tables the movement flows perfectly. But with an <b> even number </b> of tables the <b> EW pairs </b> need to <b> skip </b> one table halfway through the movement, otherwise they would run into boards they have played already (but see <b> alternative solution </b> <a href=#05a> below </a> ). <p align=justify>If you wish to use a full set of boards aim to have between 18 and 24 boards in play. <br> Place therefore</p> <ul><font color=#000099> <li>4 boards on each table for a <b> 5-table Mitchell </b> (total = 20 boards) <br> <br></li> <li>4 boards on each table for a <b> 6-table Mitchell </b> (total = 24 boards, but 20 boards played due to the skip) <br> <br></li> <li>3 boards on each table for a <b> 7-table Mitchell </b> (total = 21 boards) <br> <br></li> </font><li><font color=#000099> 3 boards on each table for an <b> 8-table Mitchell </b> (total = 24 boards, but 21 boards played due to the skip) </font></ul> <p align=justify>Shown below are the movements of players and boards in a <b> 5-table Mitchell </b> movement at the end of the first round.</p> <p></p> <center> <img alt=dup05.gif border=0 height=600 src=dup05.gif width=480> </center> <p align=justify>In a Mitchell movement all NS pairs compete against each other, and separately all EW pairs also compete against each other.

(From Table 4 boards move to the Bye table. Boards from the Bye move to Table 3.) <br> Now the EW pairs do not have to skip after round 3, but move up one table as normal, while not running into boards they have played already. So with this movement <b> all EW pairs </b> play against <b> all NS pairs </b> , and <b> all pairs </b> play <b> all boards </b> . <br> A similar setup can be used for an <a href=mitchell_08.gif target=_blank> 8-table Mitchell </a> . <br> <br> <a name=06> </a></p> <center> <hr> <a name=06> <font size=3> ( </font> </a> <font size=3> <a href=#07> Down </a> - <a href=#05> Up </a> - <a href=#00> Top </a> ) </font> <p></p> </center> <font color=#ff0099 size=+2> DUP 6 - Howell movements for Pairs </font> <p align=justify><font size=3> In a Howell movement each pair competes against all (or most) other pairs.

In this case you follow the Howell movement directions for the <b> players only </b> , and ignore the distribution of boards. <br> For a 5-table Howell for example place 1 board on each table to be shuffled, dealt and played. After all boards have been played on one table they move to the next lower numbered table to be played there too. Repeat this process once more. Then (after each board has been played on three separate tables) all players move for the next round (as indicated on the Howell guide cards) and all boards are shovelled and dealt again. <br> This manner of play has the advantage that you can stop the session after any round if you wish.

When the timer rings <b> no more boards are to be started </b> . Any boards left unplayed as a result are allocated an <b> average score </b> .

The hall mark of a good player is that he keeps smiling and is supportive of his partner no matter what. Don't point out partner's mistakes (you never make them of course) and hand out a quick bridge lesson (you never need one of course) at the end of each deal, it will only have the reverse effect you intended. </font></p> <p align=justify><font size=3> The <b> first responsibility of all players </b> is therefore to <b> be courteous </b> at the table <b> at all times </b> . Be humble in your victories and graceful in your defeats. Above all keep your partner smiling and happy, it will greatly improve his game as well as yours. </font></p> <p align=justify><font size=3> <b> All players </b> must check on the Movement guide card that they are sitting at the right spot at the right table for each round. </font></p> <p align=justify><font size=3> <b> All players </b> are responsible for <b> counting their cards </b> (face down) immediately after taking them out of the duplicate board. If you do have an incorrect number (12 or 14 cards) <b> call the Director </b> . </font></p> <p align=justify><font size=3> <b> All players </b> must <b> not waste time </b> . <br> Do not sit agonising endlessly over every bid you make or every card you play. Doing so wastes time allocated for each board and penalises all players at your table. This is bad selfish behaviour and most unsportsmanlike. <br> Bridge is not just about making the right decisions. It is about making decisions within a short span of time. With the benefit of hindsight we all would be perfect players. Also making mistakes will help you to become a better player. Agonising over every move will keep you bogged down forever. </font></p> <p align=justify><font size=3> <b> N players </b> are responsible for writing the results on the travelling score sheet after each deal. <br> If you notice (what you believe is) an incorrect entry by another table on the score sheet <b> do not correct it </b> , but write a question mark (?) behind it.

These are available from all bridge supply shops, but can add up to a considerable expense. <br> Smaller clubs therefore generally use bidding slips on which each player writes (with a pen or pencil) his bid each time his turn comes around. <br> <br> Below an example of such a bidding slip. <br> </font></p> <ul><font size=3> <font color=#000099> <li>Bids are written as 1H or 2S or 1NT (or 1N) <br> <br></li> <li>A <b> Pass </b> is shown as a diagonal line across the box, from bottom left to top right (from the writer's perspective) <br> <br></li> <li>A <b> Double </b> is shown as a cross from corner to corner</li> </font> </font></ul> <font size=3> <br> <center> <img alt=dup06.gif border=0 height=270 src=dup06.gif width=450> </center> <p align=justify>Here is an example of the use of a bidding slip, with North being the Dealer. <br></p> <center> <img alt=dup07.gif border=0 height=375 src=dup07.gif width=540> </center> </font> <p align=justify><font size=3> The bidding ends after three successive passes (diagonal lines). The final pass is commonly (but not necessarily) shown as a double parallel diagonal line. <br> <br> The great advantage of this method of silent bidding is that each player can see the entire bidding sequence as it evolves, without having to remember or ask. At the end of the auction the bidding slip is removed before the Dummy goes down on the table. For each deal a new bidding slip is used. <br> When using bidding slips make sure to have <b> 4 pencils on each table </b> . (Alternatively, like in many clubs, players have to bring their own.) <br> <br> A printout sheet with bidding slips is provided in the <a href=#dl> Download section </a> below. <br> Bidding slips in handy tear-off blocks are commonly available from bridge supply shops. <br> </font> <br> <a name=dl> </a></p> <center> <hr> <a name=dl> <font size=3> ( </font> </a> <font size=3> <a href=#bt> Down </a> - <a href=#10> Up </a> - <a href=#00> Top </a> ) </font> <p></p> </center> <font color=#ff0099 size=+2> DUP 11 - Download material </font> <p></p> <center> <table><tbody><tr><td><a href=../scoring/score.htm> Score calculations </a>   <a href=../scoring/scoresh.gif> Score sheets </a>   <a href=../scoring/score_calc.jpg target=comp> Score Computer </a> <p><a href=../scoring/comp0.htm target=comp> One Table Bridge </a> - <a href=../scoring/comp01.htm target=comp> Score sheets </a> - <a href=../scoring/comp02.htm target=comp> Calculator </a> <br> <br> <a href=../br_laws.htm> Laws for the most frequently occuring offences </a> <br> <br> <a href=dupbid.gif> Silent Bidding slips </a> <br> Pads of 500 double sided Silent Bidding Slips, wallets, boards, Travelers and much more are also available online in <b> Australia </b> from <a href=http://www.bridgegear.com target=_blank> Paul Lavings Bridge books & Supplies </a> <br> <br> Table numbers : <a href=table1.gif> 1 and 2 </a>   <a href=table3.gif> 3 and 4 </a>   <a href=table5.gif> 5 and 6 </a>   <a href=table7.gif> 7 and 8 </a>   <a href=table0.gif> blanks </a></p> <p align=justify>If you find scoring by hand too difficult or (more likely) too boring I can recommend a great (very easy to use) <b> computer application </b> which can do that for you : <a href=http://www.scorebridge.com> <b> ScoreBridge </b> </a> .
