The story

There’s no such thing as the Castle Gambit.

Castle Gambit is a web app for over-the-board chess at local clubs, named after an opening that doesn’t exist.

The name

Two moves every player knows.

Castle Gambit comes from two words every chess player learns early. Here’s what each one does on the board.

Gambit

5432efg

A gambit is when you give something up early to get something better, like the pawn White offers in the King’s Gambit.

Castle

castling
21efgh

Castling is when you tuck your king behind a wall of pawns and a rook so nothing can reach it.

One is a risk. The other is the opposite of a risk.

In four hundred years of chess, nobody put them together.

Club night

The move nobody named.

Every player who has ever walked into a club night has put them together. You give up an evening: the couch, the phone, the certainty of playing someone you’ll never meet. You make a small, real sacrifice and sit down across from a stranger. What you get back is the thing every king is looking for: a castle. A place where your people are.

What Castle Gambit is

That’s the move we built this for.

Castle Gambit is a web app for chess at your local club, and it speaks the story’s language. Every club here is a Castle: a real room in a real town with real boards. Every open game, meetup and tournament is a gambit: an offer out in the open, waiting for someone to accept it.

On club night, that means:

  • Scan the code on the poster, tap Find me a game, and your phone tells you your board, your color and who you’re playing: someone close to your level. How Castle Gambit pairs
  • After the game you both tap the result. When your two copies match, it counts toward a friendly rating, kept as tally marks for your first five games. Castle Gambit’s social rating
  • Organizers get a join code, a poster for the door, a club TV that shows who’s waiting and who’s on which board, and the night’s results. Running it with Castle Gambit
