Welcome to Four Player Chess
Rules
Pieces move and capture like always (though there is no en passant at this time)
Points are usually earned by capturing pieces: Pawns are +1 point, Knights are +3, Bishops and Rooks are +5, Queens are +9, Kings are +20
Checkmate eliminates a player and earns +20 points
Your pawns promote to Queens on your 8th rank (at the center of the board)
Promoted Queens are worth only 1 point
Dead (grey) pieces in the armies of eliminated players do not provide points
Delivering a double-check is worth +5, and triple-checks are worth +15
When a player resigns or times out, leaving two or more active players on the board, their King remains in color and is still worth +20 to whoever can capture it; but if there are only two players remaining, the remaining player will be given +20 points
The player with the most points at the end, wins!
Stalemate will result in +20 for whoever caused it (including the stalemated player)
