In chess variants "anti-chess" (also known as "losing chess", "giveaway chess", "suicide chess"), a player wins by giving away all of their pieces. If a capture is possible, it is mandatory to make the capture. The basic rules of chess are preserved, but the king loses its special status and behaves like a regular piece. Consequently, there is no castling, no checks, and it's allowed to move into capture.
To play online with real players, as well as online bots, go to the "tables" tab, select a table that suits your parameters and join the game. You can also create your own gaming table with the desired settings by clicking the "create game" button. In training mode, you can play offline with yourself or with the computer. The more time you give the artificial intelligence to think, the better it will play. In addition, if the game is new to you and you want to understand what strategy and tactics to follow, you can choose a CPU vs. CPU game and watch the process.
