Checkmate

Here's a little doodle, I drew my self. I see a chess board, And every piece, I'm afraid to move. If I'm going to play the game, I must place my name. Am I a king, a queen? well, I did sing: A rook, pawn, bishop, I’m a knight, That sounds right. Every move, It makes me want to faint, Is this a trait or mental illness state? Now I'll fall, But, If I control my destiny, I can't stall. Checkmate! I'll take a prostitute at this rate. In the end, It doesn't matter, If you're sane or plane, Just that you played the game.
