Position features
The king starts on b1, the rooks on a1 and g1, the queen on h1.
From b1 the king makes the longest journey Chess960 allows when castling short: five squares to g1.
The bishops stand on e1 and f1; their long diagonals reach a5 and a6 once the d- and e-pawns step aside.
The pawn on c2 is defended by the king alone — the same soft spot f2 is in the classical setup.
The setup belongs to the RampartGuard family; read right to left it becomes position 389.
The engine's main line opens with g4.

Commentary
The king begins on b1, and short castling takes him five squares across the board to g1. The bishops sit together on e1 and f1, the knights side by side on c1 and d1. The pawn on c2 leans on the king alone; no other second-rank pawn starts short of a defender. The queen begins in the far corner on h1, the second rook in the corner on a1. White's edge here is a wide one, +31 centipawns: g4 a5 h4 g6 e3 e5.
