• PvP - play with friends.
• Bot works in any group or private chat.

Usage

To play chess simply type @chessy_bot[SPACE] to your telegram message input box.

Then choose a side you want to play with. You will see an inline message with a chess board and a "Join to game" at the bottom.

When someone join your game, this will be displayed in the status message. Also the "Join to game" button will become "Settings".

Now everything is ready to start the game. To move your pieces just select a piece you want to move and then select a destination from displayed available to move squares.

WARNING!!!

The board is rotating each turn by default! The active player always placed at the bottom!
