oh, and I meant to ask about #1. Are you sure that's right - there aren't a whole lot of 10 letter words out there where the first letter is repeated. The 12 I did find don't fit...
What if you deal 2 cards of the same rank back to back - i.e., J of hearts followed by J of spades. Would they be in the same pile or different piles? Does one suit outrank another?
