Full Double Chess


Sergey Sirotkin


The idea of Full Double Chess is very simple: I wanted to place on a large board all combinations of all of the simple Chess pieces.

Board and Setup

Full Double Chess initial setup.

King: h1, i1
Amazon: g1, j1
Queen: f1, k1
Chancellor: d1, m1
Cardinal: e1, l1
Rook: a1, p1
Bishop: c1, n1
Knight: b1, o1
Pawn: a2, b2, c2, d2, e2, f2, g2, h2, i2, j2, k2, l2, m2, n2, o2, p2
King: h8, i8

Queen: f8, k8
Chancellor: d8, m8
Cardinal: e8, l8
Rook: a8, p8

Knight: b8, o8
Pawn: a7, b7, c7, d7, e7, f7, g7, h7, i7, j7, k7, l7, m7, n7, o7, p7

Combination Pieces

Full Double Chess uses the following combination pieces not used in International Chess: the Amazon (a combined Queen and Knight), the Chancellor (a combined Rook and Knight) and the Cardinal (a combined Bishop and Knight).


The game is played by rules of International Chess with the exception of the board and setup, and following rules:


Allow Kings to castle when attacked or through or to attacked squares when a player still has two of them on the board.

Computer Play

An implementation of Full Double Chess has been written for Zillions of Games. You can download it here:
