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>

387
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>
