Pawn peculiarities

Pawns capture differently from how they move (straight move, diagonal capture).
There is no initial double-push, and thus no en-passant capture.
Pawns promote to Ferz when they reach last rank; there is no choice.

General rules

It is not allowed to expose your King to check.
The game is won by checkmating the opponent's King.
Stalemate (no legal moves, but not in check) is a draw.

Differences with FIDE

The Queen and Bishops are replaced by Ferz and Elephant. Pawns start on the third rank. Promotion always to Ferz.

Strategy issues

It is not possible to force checkmate on a bare King with just a single Ferz, Elephant or Knight (in addition to your own King). Two Knights or two Ferzes cannot do it either.
