Edward says his brother, Ethan, forced him to learn chess when he was only a kid. At first, Edward lost all the time, but he eventually got better. He respects and thanks Ethan for teaching him how to play chess, which is something he enjoys now.

When the teacher asked me the questions, I was caught with my pants down.
Now I have chess under my belt.
I really have to take my hat off to my teacher.
I got mad and left at the drop of the hat.
