Bridge Night RSVP Website: Pair Counts, a Table Cap, and a Board Line
A bridge night RSVP has to lock a pair and a table before the first board, because a maybe does not hold a seat.

A bridge night breaks when three tables are set and you are still short a pair, or when the movement was built for twelve and three of those names were still a maybe on Friday. Pairs, the four seats at each table, and the number of boards you will actually play are set before the first board comes out. The host does not deal a fourth table because a neighbor decided to play after the sheet closed. This is contract bridge, four players and a named partnership, not chess and not mahjong. A maybe does not hold a seat.
You can create a bridge night RSVP that fills the tables you will actually set, records who is sitting North-South or East-West, and stops when those seats are full.
Count the players the tables can hold
Walk the room before you send the link. Write down how many tables you can set with four chairs, a bidding box or a pad at each seat, and a stack of boards. If you can run three tables, that number is your cap: twelve players, in six named pairs. A table of three cannot start a board.
A bridge table is two partnerships, North-South and East-West. Duplicate means the same boards move, so every table has to be full or the comparison breaks. Ask whether a person who will not play can sit away from the table, and whether that person still counts toward the chairs in the room. Pick one rule and write it on the page. Kibitzers stay off the open table. They do not claim a thirteenth seat or turn a foursome into a five-person auction.
Ask the last time you can change the movement without losing the room. If you lock the pairs on Wednesday for a Friday start, that Wednesday is your lock. Write the finish too: four named players per table, boards played in order, cards back in the board when the set is done. A pickup game "if someone brings a friend" is not a plan.
Set a capacity limit on table seats, not on everyone who was invited to watch. When the twelfth seat is taken, the form should say the night is full. If the movement is already written, a late pair is not at these tables.
The board line is a number, not a vibe
Name the session you will play and stop there. A clear line is duplicate, partnerships named in advance, and 18 boards. Rubber bridge, with a running rubber and no boards to pass, is a different night. Chess, with pieces, is a different outing. So is mahjong, with tiles and a wall.
Put 18 boards on the form as the session you will finish, not a vague "until people are tired of bidding." If the night is 18 boards, that is the line. People who want to "see who shows up and then deal" will leave you with a table that cannot open a board. You need a yes to this pair, this table, and this board count before you write the movement.
Where you sit, and what the table has to allow
Nights go wrong when a pair is one name, or when a player cannot reach the bidding box from the chair you assigned. Ask for both partners' names, whether they sit North-South or East-West, and whether either player needs a firmer chair, a larger-print card, or a seat that does not require a step. A guest who is only watching the play does not get a hand.
Collect seating preferences so a partnership stays together and a player who needs the end chair is not put in the tight corner. Ask about accessibility needs before you set the room, including a chair that works for a long sit and a table height that lets someone read the board. Write what happens if a pair is short one player at the start: the table waits only until the time you named, then a standby pair already in the room sits down, or that table's boards are skipped and the late pair does not cut into a hand in progress.
The moment the movement is locked
The meeting point is the room you named, not "the club" with no table numbers. Put your phone on the page. A message in the group chat is not a seat card. You match pairs to tables.
Tie the deadline to the movement, the day the pair count cannot change. After that, a late yes is a call about a cancellation, not a promise of another table. If you want a pair ready when someone drops, keep them as standbys and tell them they do not have seats until you write back. A maybe does not hold a seat.
Export the list the morning you lock: attending or not, partner's name, North-South or East-West, accessibility note, and phone. A bridge RSVP is finished when every table has four named players, the board line is 18, and a late pair knows whether they are sitting down or going home.
