The reason it is 10x12 instead of 8x8 is the bounds checking. For example, if you were in the center of the board, you could move a knight to 8 different squares. If you were sitting on a corner, you wouldn't have that many options. If you move to a square with a value of -1, then that move was illegal. Bitboards involve using 64 bit words to represent boolean conditions. There are a couple sites out there detailing the specifics.
