Pawn peculiarities

General rules

Differences with FIDE

The Commoner (Man) replaces the Queen. The Ferz and Alfil (Elephant) from Shatranj are added, and the board width expanded to accomodate them. The Pawns have no double move. There is no castling.

Strategy issues

It is not possible to force checkmate on a bare King with just a single Bishop or Knight, Ferz or Wazir (in addition to your own King). Two Knights, Ferzes or two Wazirs also cannot do this, and F + W only in rare situations. The Commoner can force checkmate against a bare King.

Alfils are not only color bound, but also skip over half the files and ranks. So they can only reach 8 squares, making them next to worthless.

Bishops are confined to squares of a single color. Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
