Tremendous Chess is a large chess variant invented by Vadrya Pokshtya that is played on a 16×16 chessboard with 112 pieces per player and the starting position shown above.
No pawns, no castling, no promotion zone.
The goal is to checkmate the opponent's king.
The chess pieces move and capture according to the rules of standard chess.
Tremendous Chess is played according to the rules of progressive chess, i.e. players, rather than just making one move per turn, play progressively longer series of moves. The game starts with White making one move, then Black makes two consecutive moves, White replies with three, Black makes four and so on. (The move number is equal to the number of moves in a series available to a player on that turn.) Series are continuous and there are no restrictions on individual moves in a series except for the following:
A check may only be given on the last move of a full series (for example, on
move six, a check can only be given on the sixth move), while checkmate
can be delivered on any move of the current series. If the only way to escape
a check is to give check on the first move of the series, then the game is lost
by the player in check by progressive checkmate.
If at any stage a player has no legal moves but is not in check, the game is
a draw by progressive stalemate.
A check must be escaped from on the first move of a series—if this cannot
be done, it is checkmate and the game is lost.
