I've been teaching Phoebe how to play chess for about two years.  The thing about chess is that with as much strategy is involved, it can take years to learn how to play properly, as opposed to just knowing how all of the pieces move.  She's known how to move the pieces for more than the two years, but Phoebe hates losing, and that applies to anything, even a game where you learn by losing.  She's very, very smart, and has what it takes to learn the strategy of the game, and looking several moves ahead, but what she doesn't have, is patience.  She's getting there, but I think it might be a few more months of playing every week before she's really got it down.
