Respect the power of three Wazirs - they can checkmate a lone King in 47 moves.
True. But not very relevant. Three Ferzes do it faster when not all on the same color. (Addmitted, this rules out 1/4 of the cases.) But in Shatranj stalemate is a win, and even two Ferzes or Wazirs can force that on a bare King. And the worst case for the Ferzes is two moves faster than for the Wazirs, even when they are on the same color.
