 448   <h3>Pawn peculiarities</h3>
 449
 450   <ul>
 451     <li>Pawns capture differently from how they move (straight
 452     move, diagonal capture).</li>
 453
 454     <li>Pawns can move two squares straight ahead from their
 455     initial position, provided they are not blocked.</li>
 456
 457     <li>On the move immediately after such a double push, they can
 458     be captured en passant by another Pawn, as if they had only
 459     moved 1 square ahead.</li>
 460
 461     <li>Pawns promote to a piece chosen from the set of captured or
 462     substituted pieces when they reach last rank. The chosen piece
 463     is then removed from this set.</li>
 464   </ul>
 465
 466   <h3>Castling</h3>
 467
 468   <p>A King that has not moved before can move two squares in the
 469   direction of a Rook that has not moved before, in which case that
 470   Rook is moved to the square the King skipped over. This is only
 471   allowed if all squares between King and Rook are empty, when the
 472   King is not in check on the square it came from, and would not be
 473   in check on any of the squares it skipped over.</p>
 474
 475   <h3>General rules</h3>
 476
 477   <ul>
 478     <li>It is not allowed to expose your King to check.</li>
 479
 480     <li>The game is won by checkmating the opponent's King.</li>
 481
 482     <li>Stalemate (no legal moves, but not in check) is a
 483     draw.</li>
 484   </ul>
 485
 486   <h3>XBoard interface issues</h3>
 487
 488   <p>When a Pawn can be promoted, XBoard first advances it as a
 489   Pawn to the promotion square. Then it waits for you to complete
 490   the move entry by clicking on the piece in the holdings beside
 491   the board that you want to promote to. You can use the New
 492   Shuffle dialog to control the randomization of the initial
 493   position.</p>
 494
 495   <h3>Differences with FIDE</h3>
 496
 497   <p>The start position contains four unorthodox pieces. Promotion
 498   only to pieces that were captured before (or substituted).</p>
 499
 500   <h3>Strategy issues</h3>
 501
 502   <p>It is not possible to force checkmate on a bare King with just
 503   a single Bishop or Knight (in addition to your own King). Two
 504   Knights cannot do that either.</p>
 505
 506   <p>Bishops are confined to squares of a single color. Having
 507   Bishops on both colors compensates this weakness, and is worth an
 508   extra 0.5 on top of their added value.</p>
