It's hard to tell, because the distribution of pieces on the wheel is not clear. Also, you have to assume that the choices made when choice, hawk, or elephant are spun are random. But if each piece has an equal chance of being spun, then each piece has an even chance of being on a1 (except the king, which would be illegal). But a quick check of the 960 legal positions shows that while knights and rooks do have a 25% chance of being on a1, rooks have a 37.5% chance and queens have a 12.5% chance. So the roulette wheel biases away from rooks in the corner and towards queens in the corner. And I believe there was some consternation with queens being in the corner at that event.Ichabodhttps://www.blogger.com/profile/18128802270405657672noreply@blogger.com
