Okay, make it Modern, then, if I still have the option.
I might suggest that Great Shatranj is just a modest variant of Capablanca Chess; one where the infinite sliders are 'reduced' to a 1 square step or a 2 square leap, instead of their cross-board [linear] slides. :-)
However, Modern will do. [And if it won't do, then how about Hypermodern Shatranj, which is even closer to standard chess? ;-)]
