420 <h3>Pawn peculiarities</h3>
423 <li>Pawns capture differently from how they move (straight
424 move, diagonal capture).</li>
426 <li>There is no initial double-push, and thus no en-passant
429 <li>Pawns promote to Ferz when they reach last rank; there is
433 <h3>General rules</h3>
436 <li>It is not allowed to expose your King to check.</li>
438 <li>The game is won by checkmating the opponent's King.</li>
440 <li>Stalemate (no legal moves, but not in check) also counts as
444 <h3>Differences with FIDE</h3>
446 <p>The Commoner (Man) replaces the Queen. The Ferz and Alfil
447 (Elephant) from Shatranj are added, and the board width expanded
448 to accomodate them. The Pawns have no double move. There is no
451 <h3>Strategy issues</h3>
453 <p>It is not possible to force checkmate on a bare King with just
454 a single Bishop or Knight, Ferz or Wazir (in addition to your own
455 King). Two Knights, Ferzes or two Wazirs also cannot do this, and
456 F + W only in rare situations. The Commoner can force checkmate
457 against a bare King.</p>
459 <p>Alfils are not only color bound, but also skip over half the
460 files and ranks. So they can only reach 8 squares, making them
461 next to worthless.</p>
463 <p>Bishops are confined to squares of a single color. Having
464 Bishops on both colors compensates this weakness, and is worth an
465 extra 0.5 on top of their added value.</p>
