263 Moves (<a href="Betza.html">Betza notation</a>)
275 Can castle with Rook, moving 3 steps towards it
345 Promotes to Q, R, B, or N on reaching last rank
347 <h3>Pawn peculiarities</h3>
349 <li>Pawns capture differently from how they move (straight move, diagonal capture).</li>
350 <li>Pawns can move two squares ahead from their initial position, provided they are not blocked.</li>
351 <li>On the move immediately after such a double push, they can be captured en passant by another Pawn,
352 as if they had only moved 1 square ahead.</li>
353 <li>Pawns promote to another (non-royal) piece of choice when they reach last rank.</li>
357 A King that has not moved before can move <b>three</b> squares in the direction of a Rook that has not moved before,
358 in which case that Rook is moved to the square next to the King on the other side.
359 This is only allowed if all squares between King and Rook are empty,
360 when the King is not in check on the square it came from,
361 and would not be in check on any of the squares it skipped over.
363 <h3>General rules</h3>
365 <li>It is not allowed to expose your King to check.</li>
366 <li>The game is won by checkmating the opponent's King.</li>
367 <li>Stalemate (no legal moves, but not in check) is a draw.</li>
369 <h3>Differences with FIDE</h3>
371 The Chancellor and Archbishop pieces are extra, and the board is expanded to accomodate them.
372 To handle the larger board width, the King moves 3 squares on castling.
374 <h3>Strategy issues</h3>
376 It is not possible to force checkmate on a bare King with just a single Bishop or Knight (in addition to your own King).
377 Two Knights cannot do that either.
378 The Archbishop can force checkmate against a bare King.
381 Bishops are confined to squares of a single color.
382 Having Bishops on both colors compensates this weakness, and is worth an extra 0.5 on top of their added value.
385 As Chancellor and Archbishop are nearly equal in value to Queen, under-promotion is very common,
386 and there is virtually never any need to promote to R, B or N.
389 The super-pieces (Q, C, A) devaluate by the presence of lower-valued opponent pieces.
390 As a result trading Q for R + B is in general a good trade when you still have both J,
391 as the latter gain in value by eliminating the opponent's R and B,
392 which is more compensation than the intrinsic value difference between Q and R + B.
