context_page_description: Musketeer chess is a chess variant invented by Zied Haddad in 2011, inspired by Seirawan Chess. The game was published in 2012.
  The main difference from Chess is the addition of two other pieces.
  Musketeer Chess, uses a panel of 10 different pieces, allows 45 possible piece combinations and 21 different initial piece placements for each combination = 945 possible start positions, without changing the position of the classic pieces.
  Musketeer Chess became commercial around 2015, partnership with the House of Staunton.
context_section_description: The newly Added pieces will be dropped on a square left vacant, by a piece that moved for the first time.
  This Gating squares, are not left random and both sides will specify their choice, alternating for each piece.
  White starts the selection of the "Gate" for the first piece. Then Black selects the gate for the same piece.
  White again chooses the gate for the second piece. Black finishes by selecting the gate for the second piece. The Gating Selection is a figure like waiting in a gate at the airport before boarding.
  
  The additional pieces will be "gated" (dropped) once the piece in the first rank in front of it, clears the square for the first time. 
   
  Gating Selection is as follows: White begins with W1 piece (Spider in the previous example). Let's chose a concrete case: White decides to "Gate" his Spider after the Bishop f1. When the Bishop-f1 moves for the first time, the Spider will be dropped on the vacated square f1 at the same time. This is a special move involving two pieces. 
  On the Board, the maneuver is performed as follows: white will place his Spider behind the Bishop f1 (in a virtual square f0). On a lettered Chess Board, White will put the Spider near the Bishop f1 on the f letter (this could have been the Rank zero).  
  It's now Blacks turn: Black chooses to gate his Spider on square g8, after the Knight g8 moves for the first time. 
  It's again whites turn to chose the Gating square for his second piece, the Archbishop. The procedure is like described for the first piece. The Archbishop cannot be placed in the same square than the Spider, as it's not possible to introduce both additional pieces at the same time. In the shown example, White Archbishop will be introduced on b1 square.
  it's Blacks turn to select the Gating square for his Archbishop (d8 square as shown in the diagram).
caption: The game can now Begin. Piece Selection Phase (Spider and Archbishop selected) and Gating selection Phase finished. White pieces will gate on f1 for Spider and b1 for Archbishop. Black pieces will gate on g8 for Spider and d8 for Archbishop.
