Opening book and replies

The data presented here is the result of a collective effort from users of BGonline.org. All of the critical play have been made using high setting (XGR+, 4-ply or 3-ply). The data has been completed with rollouts made using XG2 (2-ply checker, 3-ply red cube) and XGRoller++ data.
