This chess game lets you play this cerebral sport against the computer and offers 3 levels of difficulty (from novice to advanced), back move and the back-up of current game, but not the choice of black pieces, what a pity!
Choose the level of difficulty. Click on the piece then on its destination square. In case of error or haste, click on the button "Undo Move" to return to the previous move.
A context menu should be shown when right-clicking or, on touch devices, long-pressing in the game. This menu especially allows to play in full screen and control the volume.
