Eldest is really into games right now, and we decided to preliminarily teach him chess. I don't expect him to get it overnight, though, if I may brag, I was playing chess at 4. For now, I'd love him to know what the pieces are, where they initially go, and how they move. He's apt to learning, but he also wants to play his own way. That means his knight (he's calling it a horse, though he's not calling a rook a castle yet) takes every of his opponent's pieces on the board and moves wherever it wants. It makes sense, I suppose, to a 3-year-old, a horse should be able to move everywhere.
The other cute thing -- when he first saw the bishop, he thought it looked like a rocket and flew it around the board. And when he heard us call it a bishop, it just made sense that we weren't calling it a bishop, but a spaceship. Does the multi-level chessboards on "Star Trek" have spaceships? Just wondering.
Anyway, he's having fun, and eventually, he'll learn. In the meantime, my king gladly can be checkmated by a spaceship.
