I regret the chosen options to represent the pieces:
The Gazelle (that's the original name) moves like what we call a Camel. Why chosing a Giraffe to represent it?
The Great Ferz moves like the Giraffe in Tamerlane Chess. Why chosing a Chancellor, represented by Rook+Knight, to represent it?
These are unfortunate choices, adding confusion. I'd like to see them changed one day.
By the way, this is the only variation which can be considered as Turkish. It appeared in 1805-06 in a Turkish Encyclopedia authored by Muhammad Hafid.
All other variants are not Turkish but Indians. See Murray for details.
(Gollon copied Murray but did a big mistake here. Pritchard pointed Gollon's mistake as well.). Too bad that those mistakes are continued here.
