407   <h3>Pawn peculiarities</h3>
408
409   <ul>
410     <li>Pawns capture differently from how they move (straight
411     move, diagonal capture).</li>
412
413     <li>Pawns can move two squares ahead from their initial
414     position, provided they are not blocked.</li>
415
416     <li>On the move immediately after such a double push, they can
417     be captured en passant by another Pawn, as if they had only
418     moved 1 square ahead.</li>
419
420     <li>Pawns promote to another (non-royal) piece of choice when
421     they reach last rank.</li>
422   </ul>
423
424   <h3>Castling</h3>
425
426   <p>A King that has not moved before can move <b>three</b> squares
427   in the direction of a Rook that has not moved before, in which
428   case that Rook is moved to the square next to the King on the
429   other side. This is only allowed if all squares between King and
430   Rook are empty, when the King is not in check on the square it
431   came from, and would not be in check on any of the squares it
432   skipped over.</p>
433
434   <h3>General rules</h3>
435
436   <ul>
437     <li>It is not allowed to expose your King to check.</li>
438
439     <li>The game is won by checkmating the opponent's King.</li>
440
441     <li>Stalemate (no legal moves, but not in check) is a
442     draw.</li>
443   </ul>
444
445   <h3>Differences with FIDE</h3>
446
447   <p>The Chancellor and Archbishop pieces are extra, and the board
448   is expanded to accomodate them. To handle the larger board width,
449   the King moves 3 squares on castling.</p>
450
451   <h3>Strategy issues</h3>
452
453   <p>It is not possible to force checkmate on a bare King with just
454   a single Bishop or Knight (in addition to your own King). Two
455   Knights cannot do that either. The Archbishop can force checkmate
456   against a bare King.</p>
457
458   <p>Bishops are confined to squares of a single color. Having
459   Bishops on both colors compensates this weakness, and is worth an
460   extra 0.5 on top of their added value.</p>
461
462   <p>As Chancellor and Archbishop are nearly equal in value to
463   Queen, under-promotion is very common, and there is virtually
464   never any need to promote to R, B or N.</p>
465
466   <p>The super-pieces (Q, C, A) devaluate by the presence of
467   lower-valued opponent pieces. As a result trading Q for R + B is
468   in general a good trade when you still have both J, as the latter
469   gain in value by eliminating the opponent's R and B, which is
470   more compensation than the intrinsic value difference between Q
471   and R + B.</p>
