SP-132 · RampartScout — King on the wing (b/g) with a knight on the rim (a/h) — the rarest family.
Move the pieces right on the board — full Chess960 rules, castle by dropping the king on the rook.
Position features
The king starts on g1, the rooks on d1 and h1, the queen on e1.
The king already stands on its castled square, so castling short moves only the rook, from h1 to f1.
The bishops stand on b1 and c1; their long diagonals reach h7 and h6 once the c- and d-pawns step aside.
The pawn on g2 is defended by the king alone — the same soft spot f2 is in the classical setup.
The setup belongs to the RampartScout family; read right to left it becomes position 830.
The engine's main line opens with e4, putting a pawn straight into the centre.
Every sentence here is computed from the setup itself and can be checked on the board.

Commentary
Both castling moves need only one piece to travel: the king already stands on g1, the rook already on d1. A knight begins in the corner on a1 with b3 as its only move; the knight on f1 has e3 and g3. The queen is on e1, the bishops on b1 and c1. The pawn on g2 is defended by the king alone. The engine's main line opens e4 d5, then exd5 Nb6 Ne3 f5 — the centre is traded on the third half-move.
