   8 <h1>No Castle</h1>
   9 <p>
  10 This is a shuffle variant of normal Chess, which in general destroys the possibility to castle,
  11 as the King and Rooks are also shuffled.
  12 For uniformity, castling is therefore always forbidden.

  17 <h3>Initial setup</h3>
  18 <p>
  19 There is no fixed setup;
  20 the back-rank pieces are randomly shuffled with certain restrictions.
  21 Black's setup is the mirror image of white's, though.

 338 <h3>Pawn peculiarities</h3>
 339 <ul>
 340 <li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
 341 <li>Pawns can move two squares straight ahead from their initial position, provided they are not blocked.</li>
 342 <li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
 343 as if they had only moved 1 square ahead.</li>
 344 <li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
 345 </ul>
 346 <h3>General rules</h3>
 347 <ul>
 348 <li>It is not allowed to expose your King to check.</li>
 349 <li>The game is won by checkmating the opponent's King.</li>
 350 <li>Stalemate (no legal moves, but not in check) is a draw.</li>
 351 </ul>
 352 <h3>Differences with FIDE</h3>
 353 <p>
 354 The Back-rank pieces are randomly shuffled on the back rank in the opening setup.
 355 There is no castling.
 356 </p>
 357 <h3>Strategy issues</h3>
 358 <p>
 359 It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
 360 Two Knights cannot do that either.
 361 </p>
 362 <p>
 363 Bishops are confined to squares of a single color.
 364 Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
