376 <h3>Pawn peculiarities</h3>
379 <li>Pawns capture differently from how they move (straight
380 move, diagonal capture).</li>
382 <li>Pawns can move two squares straight ahead from their
383 initial position, provided they are not blocked.</li>
385 <li>On the move immediately after such a double push, they can
386 be captured en passant by another Pawn, as if they had only
387 moved 1 square ahead.</li>
389 <li>Pawns promote to another (non-royal) piece of choice when
390 they reach last rank.</li>
395 <p>A King that has not moved before can move two squares in the
396 direction of a Rook that has not moved before, in which case that
397 Rook is moved to the square the King skipped over. This is only
398 allowed if all squares between King and Rook are empty, when the
399 King is not in check on the square it came from, and would not be
400 in check on any of the squares it skipped over.</p>
402 <h3>General rules</h3>
405 <li>Capture is mandatory; if ay capture is possible, you cannot
406 play a non-capture.</li>
408 <li>It is not allowed to expose your King to check.</li>
410 <li>The game is won by being checkmated or being left with a
413 <li>Stalemate (no legal moves, but not in check) is a
417 <h3>Differences with FIDE</h3>
419 <p>Capture is mandatory. You win by being checkmated in stead of
420 checkmating, or by having a bare King.</p>
422 <h3>Strategy issues</h3>
424 <p>Initially having more and stronger pieces makes you more
427 <p>When the opponent has only King and Pawns left, blocking one
428 of his Pawns (e.g. with Knight or Bishop), and then carefully
429 refraining from attacking it while using your powerful pieces to
430 shephard his King towards your own Pawns, and then finally
431 sacrificing your mobile material to it, is a good way to win.</p>
