Create your own Chess bot.
Zulip supports interactive bots. Bots are little programs that have limited access to a Zulip server. They can receive messages @-mentioning them and respond with useful information, jokes, etc.
The following tasks will introduce you to using interactive bots and creating simple new bots that react to messages. This group of tasks has a high creative potential, as you can create your own bots that react to specific messages and can be integrated with various APIs.
For this task, do Task Type C for creating a Chess bot (lets you play chess against the computer or other people on Zulip; use an existing chess engine for this).
