What is Chaturanga?
Chaturanga is an ancient precursor to chess, with much the same setup but a few differences in how the pieces move.
In Chaturanga the ferz replaces the queen and can only move one square diagonally.
This piece replaces the bishop and it jumps two squares diagonally. This piece jumps over other pieces like the knight and can only capture on the square it lands on.
The pawn functions the same except it can only move one space forward, even on the first turn.
All other pieces function the same as in standard chess.
There is no castling in Chaturanga
