  <h3>Pawn peculiarities</h3>

  <ul>
    <li>Pawns capture differently from how they move (Perians
    straight move, diagonal capture, Spartans the other way
    around).</li>

    <li>Pawns can move two squares straight ahead from their
    initial position, in the direction(s) of their
    non-capture.</li>

    <li>The double-push of Persian Pawns can be blocked, but
    Hoplites can jump.</li>

    <li>There is no en-passant capture.</li>

    <li>Pawns/Hoplites promote to another piece of their own side
    when they reach last rank.</li>

    <li>Hoplites can promote to King, but only when the Spartans
    have a single King just before the promotion.</li>

    <li>Persian Pawns can not promote to King.</li>
  </ul>

  <h3>Castling</h3>

  <p>The Persian King, if it has not moved before, can move two
  squares in the direction of a Rook that has not moved before, in
  which case that Rook is moved to the square the King skipped
  over. This is only allowed if all squares between King and Rook
  are empty, when the King is not in check on the square it came
  from, and would not be in check on any of the squares it skipped
  over.</p>

  <h3>General rules</h3>

  <ul>
    <li>It is not allowed to expose <b>all</b> your Kings to
    capture <b>at the same time</b>.</li>

    <li>The Spartans can leave one of their Kings under attack, and
    as a consequence, have it captured.</li>

    <li>The game is won by checkmating the opponent's King or
    King-pair.</li>

    <li>Stalemate (no legal moves, but not in check) is a
    draw.</li>
  </ul>

  <h3>Duple check</h3>

  <p>The rule that the Spartans cannot leave both Kings attacked
  would <b>not</b> follow from a rule where you lose when all your
  Kings are captured. Because under that rule the opponent could at
  most capture one of the two in the next turn, and the next turn
  the other King could move to safety. So it is an special rule
  that leaving them both under attack is illegal, (and only then
  are you considered to be in check). In consequence that when you
  cannot get out of that check situation, you are (duple)
  checkmated. (It is as if at the begining of every turn you can
  decide anew which of your Kings is the royal one.)</p>

  <h3>Differences with FIDE</h3>

  <p>The black army is completely different.</p>

  <h3>Strategy issues</h3>

  <p>It is not possible to force checkmate on a bare King with just
  a single Bishop, Knight or Lieutenant (in addition to your own
  King). Two Knights cannot do that either.</p>

  <p>Although Captains are worth less than orthodox minors B and N,
  they can force checkmate on a bare King. As a result the Spartans
  can often win when they are a minor ahead, if one of their minors
  is a Captain (e.g. KLCKB is a win, where KBNKB in FIDE is a
  draw).</p>

  <p>A pair of Spartan Kings also can force checkmate against a
  bare King. Furthermore, Kings are tough defenders, because they
  cannot be attacked by the opponent's King. So if all the
  attacker's power is in a single piece, the defending King pair
  has nothing to fear when they protect each other. This makes even
  KQKK is a draw (provided the Spartan kings can connect).</p>

  <p>Bishops are confined to squares of a single color. Having
  Bishops on both colors compensates this weakness, and is worth an
  extra 0.5 on top of their added value.</p>

  <p>Because Hoplites can choose their path, they become passers
  very easily. This is only of limited value, though, as moving
  them around an obstructing Persian Pawn usually also gives the
  latter a free path to promotion. Hoplites do stay on the same
  color when they do not capture. A Bishop on the other color is
  thus powerless to stop their promotion.</p>
