I coulda told you that. One tends to learn passwords (inadvertently) when they're short and typed nearby often enough. (Sorry, ken.)
If I remember right, the first half of this password was on a t-shirt commemorating Belle's first half-move, although its notation may have been different.
Interesting though it is, though, I find this hacking distasteful. It was distasteful back when, and it still is. The attitudes around hackery have changed; the position nowadays seems to be that the bad guys are doing it so the good guys should be rewarded for doing it first. That's disingenuous at best, and dangerous at worst.
