  11
  12   <p>This is a shuffle variant of normal Chess, which in general
  13   destroys the possibility to castle, as the King and Rooks are
  14   also shuffled. For uniformity, castling is therefore always
  15   forbidden.</p>

 388   <ul>
 389     <li>Pawns capture differently from how they move (straight
 390     move, diagonal capture).</li>
 391
 392     <li>Pawns can move two squares straight ahead from their
 393     initial position, provided they are not blocked.</li>
 394
 395     <li>On the move immediately after such a double push, they can
 396     be captured en passant by another Pawn, as if they had only
 397     moved 1 square ahead.</li>
 398
 399     <li>Pawns promote to another (non-royal) piece of choice when
 400     they reach last rank.</li>
 401   </ul>
 402
 403   <h3>General rules</h3>
 404
 405   <ul>
 406     <li>It is not allowed to expose your King to check.</li>
 407
 408     <li>The game is won by checkmating the opponent's King.</li>
 409
 410     <li>Stalemate (no legal moves, but not in check) is a
 411     draw.</li>
 412   </ul>
 413
 414   <h3>Differences with FIDE</h3>
 415
 416   <p>The Back-rank pieces are randomly shuffled on the back rank in
 417   the opening setup. There is no castling.</p>
 418
 419   <h3>Strategy issues</h3>
 420
 421   <p>It is not possible to force checkmate on a bare King with just
 422   a single Bishop or Knight (in addition to your own King). Two
 423   Knights cannot do that either.</p>
 424
 425   <p>Bishops are confined to squares of a single color. Having
 426   Bishops on both colors compensates this weakness, and is worth an
 427   extra 0.5 on top of their added value.</p>
