Field notes
The starting formation places the king, queen, and rooks in the four central cells around each pole, with eight pawns and bishops and knights at the diagonal corners. Players can inspect the globe, cell list, labels, or move journal. The guide also describes promotion at the enemy pole and identifies pawn and knight movement choices as prototype conventions still needing comparison with the original physical game.
