Look in the menu column on the left side of the screen. Near the top under 'Play' you will see 'Start Game.' Click 'Start Game' and you will see a page where you choose what game you want to play. If you choose chess, a game board will appear. You will be White, and you will have the option of making your first move at that time. To move, clicking on a piece; then click on a place to move it to; then click 'Submit' beneath the game board.
