Results

The plan was to have a pairs tournament. 11 players showed up. It was just one short to make a pairs tournament. So, it was decided to have a duplicate match. Two teams were formed, Red and Blue.

Red team: Madan Bera,  Ambar Banerjee, Rabi Dutta, Manotosh Das, Samar Das, Chinmoy Das

Blue team: Swadhin Mandal, Satyabrata Samanta, Nirmalya Ghosh, Subhadip Chattopadhyay, Arun Saha

Players of the Blue team were all from Riverside. Since there were more than 4 players in both teams, players played in turn in some seats. In Closed Table, Blue team played North - South. The match was of 8 deals. At first, hands 1 to 4 were played at Closed Table and hands 5 to 8 at the Open Table. Then the hands were exchanged. The player and table arrangement were like this:

ABOUT PAIRS TOURNAMENT

The advantage of pairs tournament is that the luck factor will be eliminated. Half of the pairs will play the same hands in turn. Other half will play the other set of same hands in turn.

PLAY:
Except in the first round (typically 4 deals), players will not shuffle the cards. The cards will come in 'boards' and the players will replace their cards in the same slot as it came. This means that the cards will not be thrown at the middle of the table. Each player, including dummy, places his card in front of them turning them face down after the trick is over. A player can examine the cards played in the trick as long his card remains face up. Tricks won are placed vertically pointing towards the partner. Tricks lost are placed horizontally, pointing to the opponents. Thus counting won/lost tricks or retracing the order of play is easy at the end of the deal. The boards also mention vulnerability and dealer information.

Four sides of a table is marked as compass points: North (N), South (S), East (E) and West (W). N and S form the partnership in a table. So are E and W. Typically N-S pairs do not change tables. On the other hand, E-W pairs move to different tables in a strict schedule determined by the tournament director. Which pairs play N-S are determined by lottery. This does not affect the score comparison at the end.

SCORING:
Each board is scored separately. Scoring depends on the vulnerability indicated on the board. 
(1) Honors do not count.
(2) For bidding and making a part-score, add 50 to the trick total.
(3) For bidding and making a game not vulnerable, add 300 to the trick total.
(4) For bidding and making a game vulnerable, add 500 to the trick total.
The result obtained on the board is entered on the 'traveling score sheet' at the back of the board. Players may not look at that until the hand is over, since it contains a record of the hand and also how other pairs fared on the board. 

PAIR MOVEMENT:
Assume there are 4 N-S pairs and 4 E-W pairs playing the tournament. One possible schedule can be the following:

Pairs are named from 1 to 8. Boards are named from 1 to 16. Let there be 4 boards per round.

This is 4-pair Mitchell movement. Every N-S pair plays with every other E-W pair and vice versa. All pairs play all the 16 boards in different order. This is also illustrates why a pair may not look into the traveling score sheet at the back of a board.

COMPARING SCORES:
The real opponent of a pair is not the pairs they play with at different tables. The real opponents of a N-S pair are the other N-S pairs. In the above example, there are 4 N-S pairs and 4 E-W pairs. For a particular board, the top scoring N-S pair and the top scoring E-W pair will be awarded 6 [= 2*(4 - 2)] Match points. The scores of all pairs from all boards will be calculated in this manner. Based on the aggregate Match points earned, pairs may be ranked.
