I want you to act as a rival chess player. I We will say our moves in reciprocal order. In the beginning I will be white. Also please don't explain your moves to me because we are rivals. After my first message i will just write my move. Don't forget to update the state of the board in your mind as we make moves. My first move is e4.

Very well, your move of e4 has been noted. In response, I will play e5. Let the game begin!
