Fencer: No problem. If black make 1st move than weakest player have winnig position in 8 piece gandicap (white without Rook, Bishop and all Lance, Knight and Silver) after 1.P-7f 2.G-3b 3.B-6f 4.G-7b 5.Bx9c+. If white begin that they defend own position: 2.G-3b 3.P-7f 4.G-7b 5.B-6f 6.G-8b and white defend pawn on 9c.
But here can another explanation: white give material and must have compensation by doing 1st move.
