Callum for the Win

He understands how to play, but still usually loses.  Time for a new strategy!

"You play Tic-tac-toe wif me?"

"Sure."
"Okay!  I go first!"  As always, he takes the middle square.  "Your turn!"

I mark an X on the top right.

"I am X."  Makes an X over mine with his pen, claiming it as his own.  "Now it's my turn!"  Makes another X.

Yay cheating!
