Computers! Maybe it's too much for humans to know all 960 starting position, but that sure doesn't stop a computer. Especially nowadays. For people, that's three orders of magnitude. Almost like making the start of the game an extra one and a half moves to think ahead before the game starts. This will work with people and the Chess will be more on how well you can move the pieces and how they work together, instead by rote and memorization. Computers on the other hand can start with all 960 positions and start working things out way in advance and have nice book ready for when the game starts. With the time it takes on the internet, even more so. This FRC Chess 960 is just a temporary solution for computer aided games, but I think it will work quite well with peple.
