Full Tamerlane Chess
Les échecs de Tamerlan complétés
Different representations exist for Tamerlane Chess. Maybe the most intriguing is when some additional pieces come to fill vacant spaces.
This happens in a Persian manuscript called "Elliott 274", authored by al-Âmulî (14th c.) which contains a Scout (Kashshâf) in f1 and a Lion (Shûr) in j1. According to Murray (History of Chess), the rest can not be read.
The same piece are also found in an Arab manuscript, named ms 7322, from the British Museum which reproduces ‘Arabshâh's work (15th c.).

The board is the regular Tamerlane Chess board with 112 squares : 10 lines x 11 columns with two "citadel" squares.
Forbes who described this variant made many mistakes in his report, most probably purposely in trying to describe a more "logical" array. Murray followed him, apparently without further checking and he then made the same errors. Several internauts, reading Arabic, have reacted and gave the correct name of all pieces. Ivan A Derzhanski has strong linguistic knowledge and he made a decisive contribution in translating the ms 7322 diagram. We are very much grateful to him for his work.
Indeed, the result is sometimes striking and hurting our logic. However, it is what it is and we should not corrupt it.
Every player has 36 pieces. They are: 1 Shah, 1 Minister (Ferz), 1 "Sea Monster" (Luxm), 2 Giraffes (Zurâfa) , 2 Vanguards (Talî'a), 3 Horses, 1 Camel, 2 "Rukhs", 2 "Dabbâbas", , 2 Elephants, 2 Lions (‘Asad), 2 Bulls (Thaurs), 1 Revealer (Kashshâf) and 14 Pawns. Pawns are all different: they were miniature reproduction of one given major piece.
On the 3rd line, from left to right, they are: Pawn of Pawn, Pawn of Horses, Pawn of Camels, Pawn of Dabbâbas, Pawn of Minister, Pawn of Shah, Pawn of Sea Monster, Pawn of Giraffes, Pawn of Vanguards, Pawn of Lion, Pawn of Rukhs. On the 4th rank, from left to right, they are: Pawn of Bull, Pawn of Revealer, Pawn of Elephants.
Correct setup translating the manuscript illustration
The starting array shows some peculiarities:
Are those peculiarities mistakes from the copyist? One can think that they are. But, it is intriguing to see that both sides present exactly the same "mistakes". So, it can be seriously doubted that they are mistakes. Therefore, it is more advisable to present the array exactly as the original manuscript did it.
Alas, no rules have been reported for this particular variant of Tamerlane Chess.
Then, there is a place for conjoncture and several writers - including me - have tried to propose moves for the new pieces.
Moves proposed by Forbes
Forbes in 1860 was, in our knowledge, the first to make a proposal. He proposed a Lion combining the moves of Rukh and Giraffe, a Bull combining Vanguard and Giraffe (note that Forbes called the Vanguard a Scout, and gave it the move of our modern Bishop), a Revealer (that he called a Sentinel) combining Vanguard and Rukh, then being identical to a modern Queen. His Crocodile was assumed identical to the regular Vizir.
My personal proposed moves
My proposed reconstruction is based on the analysis that was made by Persian authors for regular Tamerlane Chess. They classified the pieces in 3 classes and 3 powers.
Then, perhaps the 3 new pieces were constituting a 4th power of this table?
Lion: jumps to the 3rd square orthogonally (i.e. along lines or columns).
Revealer: jumps to the 3rd square diagonally.
Bull: jumps making 1orthogonal step followed by 2 diagonal steps.
Crocodile: moves like the Vizir, 1 adjacent step (4 "orthogonal" directions: front, back, left, right).
The moves of median, extreme and long range pieces can be summarized on these diagrams:
