 323 <h3>Pawn peculiarities</h3>
 324 <ul>
 325 <li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
 326 <li>There is no initial double-push, and thus no en-passant capture.</li>
 327 <li>Pawns promote to Ferz when they reach last rank; there is no choice.</li>
 328 </ul>
 329 <h3>General rules</h3>
 330 <ul>
 331 <li>It is not allowed to expose your King to check.</li>
 332 <li>The game is won by checkmating the opponent's King.</li>
 333 <li>Stalemate (no legal moves, but not in check) also counts as a loss for the stalemated side.</li>
 334 <li>If your opponent only has a King at the beginning of your turn, and your king is not yet bare, you win.
 335 This means that after you capture the last piece, the opponent gets one equalizing turn to recapture yours,
 336 in which case it would be a draw.</li>
 337 </ul>
 338 <h3>Differences with FIDE</h3>
 339 <p>
 340 The Ferz and Alfil replace the Queen and Bishop.
 341 The Pawn have no double move.
 342 No castling.
 343 The King starts on the e-file.
 344 </p>
 345 <h3>Strategy issues</h3>
 346 <p>
 347 Because of the baring rule a win is possible with any material other than a bare King.
 348 </p>
 349 <p>
 350 Alfils are not only color bound, but also skip over half the files and ranks.
 351 So they can only reach 8 squares, making them next to worthless.
