An Arrow piece is any piece that when checking also guards the two cells in the king's field to left and right of the check line; thus we can have arrow rook, arrow bishop, arrow queen, arrow knight, arrow pawn, etc. The arrow bishop (under the name of the ‘bishops arrow’) was introduced by W. Hagemann Fairy Chess Review 1937. [Black: Ka5, Qh8; White: K d7, Pc3, B(Arrow)d4. Helpmate in 2. (b) c3 to c6. Solution; (a) 1.Qe8† Kc7 2.Qa4 ABb6‡ (b) 1.Qa8 Kc7 2.Qa6 ABc3‡]. Soon after the arrow rook (called the ‘rook's arrow’) was introduced by J. Young Fairy Chess Review 1937. [White: Kb4, R(arrow)h1, Pc2, Pd3; Black: Ke3, Nd2. Helpmate in 2. Solution: 1.Nc4 d×c4 2.Kd4 ARh4‡]. The other men in these compositions are normal chessmen without the arrow-check ability. I extended the idea to pieces in general, and these compositions published in Rex Multiplex in 1985 show arrow queens, arrow pawns and arrow knights.

In Arrow Chess any piece that checks also guards the two cells in the king's field to left and right of the check line. The check line and the two prevented flights thus form an arrowhead. Since kings cannot check each other there is no such thing as an arrow king. The kings in Arrow Chess are normal kings.
Solution:1.Kg6 Kc8 (Ka8? 2.b7 mate) 2.b7+ Kd8 3.b8Q+ Ke7 4.Qe5+ Kd8/Kf8 5.c7/Qb8 mate.
This is the first problem showing arrow pawns and arrow queen.
