I always cheated when I played battleship with my brother when we were kids.
Why would you cheat?
It was the only way to win back then.
We all like winning, but cheating isn't the answer. He will just not want to play with you again. You should figure out a way to win honestly.
I learned my lesson. I don't cheat anymore.
That's good. It's not all about winning anyway. As long as you both have fun, that's what matters.
