Twitchess is a Chrome add-on developed by tvdhout that seamlessly connects the livestreaming site Twitch with the popular chess site Lichess. With Twitchess, streamers can now accept chess challenges from their Twitch subscribers directly through Lichess.

This add-on simplifies the process by allowing subscribers to enter their Lichess username using a command in the Twitch chat. Once entered, their username will be highlighted in purple in the challenge list on Lichess, making it easy for streamers to identify challenges from their subscribers.

In addition, Twitchess adds two buttons to the challenge list on Lichess. The first button allows streamers to accept a random challenge from anyone, while the second button specifically accepts a random challenge from a Twitch subscriber. This feature adds an extra layer of engagement and interaction between streamers and their subscribers.

Overall, Twitchess is a valuable tool for Twitch streamers who want to enhance their chess streams and connect with their subscribers in a unique way. With its simple integration and user-friendly interface, Twitchess is a must-have add-on for any chess enthusiast on Twitch.
