When I was little my grandma taught me how to play chess. My brother and I would take turns playing with her when we went to her house. I'm pretty sure she always won. Or maybe she let us win sometimes.
She was just telling me about how when my grandpa came home from work he'd unwind by playing a few games of chess with her. She even beat him sometimes.
Chess is hard. And strategic. And you have to think. I've taught my boys to play and they've taught Dan to play. Sam LOVES it. He's always asking if someone will play with him. If you don't know how to play, he'll be happy to teach you. And then he'll beat the pants off you. He's beat me a few times lately. He is a thinker and he's getting really good.
Here are the rules of chess, in case you'd like to look over them.
And here are my chess-playing grandma and grandpa (stole this photo from my cousin's blog).
