ChessBuddy

Play chess with Go, HTML5, WebSockets and random strangers!

• Demo: http://chess.tux21b.org:8000/

Hint: Open the page in two different tabs, if there aren't any other visitors around.

Quick Start

ChessBuddy is compatible with Go 1. Use the go tool to install the latest version of ChessBuddy with the following command:

go get github.com/tux21b/ChessBuddy

This will install a new command ChessBuddy in your path (usually $GOPATH/bin/ChessBuddy). Start the HTTP server with the default arguments:

ChessBuddy -http=:8000 -time=5m

Visit http://localhost:8000/, wait for a friend and start playing a game of chess.

You can use go get -u github.com/tux21b/ChessBuddy to update ChessBuddy.

Features

• web service connects all visitors in pairs and maintains the chess games
• JavaScript client displays the chess board using the HTML 5 canvas API
• Time control: 5 minutes (configurable) per side, sudden death
• move history displays all moves using standard algebraic notation (SAN)

Missing / Planned Features

• support for underpomotion (currently pawns are always promoted to queens)
• add some animations to the javascript interface
• add a couple of AI players (maybe by connecting another engine such as gnuchess or crafty) which can be selected if no other visitors are available
• starting new games without refreshing the page
