Cinquain

Cinquain is the strange child of chess and gomoku.  Beginning with an empty chess board, players work to create a line of five pieces either by placement or movement. 

Each player begins with a standard chess set of sixteen pieces.  On her turn, a player can choose to place a piece on the board or move one already in play.  Pieces can be placed on any open square (the two black bishops, for example, can be on squares of the same color and pawns can be placed on any rank).  There is no limit on the number of open-ended lines of three or four a player may have.

Kings, queens, bishops, knights and rooks can be moved, following the general rules of movement in chess.  Pawns neither move nor promote, although they still count as part of a line of five.  There are two changes to a king's movement, however.  There is no capturing in cinquain, so kings can be placed and moved without worrying being in check.  Also, there is no castling.

The first player to create a line of exactly five pieces wins.
