Scharnagl> Falcon 5690334 covers all 453,600 arrays 8x10, 9x10, 10x10 and larger. There is no distinction. We recommend from playtesting RNBFQK..., RNFBQK..., RFNBQK..., FBRNQKNRBF, FRNBQK..., BRNQFFK..., RNBQFFK... Notice Rooks are always a1, b1, or c1, and King within d1 to g1. Most would not want Randomized all possibilites. You are right, it is different when Rooks are only two from King, but we recommend to avoid adjacent Rook and King. For Rook and King two apart, I will define ''free castling'' as ''not a1, not j1, and King must go at least two over, overtaking Rook if necessary or if K & R are within three.'' That means Kingside castling is fixed destination in three of the above. (Other CVs may vary.)
