   2   White has only six pawns and the king, but move twice at each turn.

  10   The white army can appear much too small, but the power to move twice in a
  11   row shouldn't be underestimated. At each turn white plays two moves with
  12   only one constraint: do not be under check in the end.
  13   So if the white king attacks a defended piece, he can take it anyway by
  14   coming back on its initial square on (sub)move 2.

  24   | The diagram position on the left looks pretty much like a checkmate,
  25   | but white can take the queen and come back to the h6 square. Finally,
  26   | white can mate in an unusual way, like the following diagram found
  27   a(href="https://en.wikipedia.org/wiki/Monster_chess") on Wikipedia
  28   | . There is no way for the black king to avoid being captured since white
  29   | plays twice (the threat is 2.d7,dxe8).
