"Bye player" or "Ghost" (DeVenezia's term) are synonymous in this discussion: In the original Berger tables, player 1 would start with two whites (v 10 & v 2) while another player (6 for 10 players) would start with black for two rounds( v 5 & v 10) so the tables were revised to correct the double-white or double-black problem. It is worth noting however, that there are only so many things that can be done to R-R tables or their long table model: renumber the players, assign the opposite color to all the fixed boards, and/or assign the opposite initial color to the bye player. My own suggestion is No. 1 has White against No. 10 while players 2-5 have Black against 9-6 respectively. Each player (other than 10) would have White before their bye round, play No. 10 with whatever color No. 10 is due (or have a bye), and Black in the following round, vice versa to the Berger tables. Player 10 would have Black against 1-5 and White against 6-9 as they came to him. These changes are already incorporated in the above example.
|Initial Minuend||Smallest ODD number > no. players||Smallest EVEN number > OR = no. players|
|Ghost's pairing number||Minuend - 1||Minuend|
|First Round Bye or Ghost pairing||Player No. 1||Minuend / 2|
|Player 1 rd. 1 seating||At Ghost Board||One position clockwise from Ghost|
|Seating of players||Counterclockwise on alternate boards||Clockwise on alternate boards|
|Rotation between rounds||Clockwise||Clockwise|
|First Round Opponent||Subtract pairing number from minuend||Subtract pairing number from minuend|
|First Round Color||Higher number has White||Higher number has White|
|Color Rule||Odd vs Even: Higher number has White. +Same: Lower has White.||Odd vs Even: Lower number has White. +Same: Upper has White.|
|Color vs. Ghost||* Lower numbers have White & vice versa||* Lower numbers have White & vice versa|
|Color assignment around Ghost||White before and Black after.||White before and Black after.|
|Next Opponent||Add 1 to last opponent. No. 1 follows highest odd.||Subtract 1 from last opponent. Highest odd follows No. 1.|
|Bye or Ghost pairing||When paired with own number.||When paired with own number.|
