Losing chess [a] is one of the most popular chess variants. [1] [2] The objective of each player is to lose all of their pieces or be stalemated, that is, a misère version. In some variations, a player may also win by checkmating or by being checkmated. Losing chess was weakly solved in 2016 by Mark Watkins as a win for White, beginning with 1.e3.
Gravity chess: After every turn, all pieces other than pawns fall towards the higher ranks of the board, until they either reach the eighth rank, or another piece or pawn in the way. [53] [54] Grid chess: The board is overlaid with a grid of lines. For a move to be legal, it must cross at least one of these lines.

In the middlegame, however, Black has slightly more freedom of movement than White and may be able to trade off the isolated pawn before an endgame ensues.
In particular, if the pawn is on its sixth rank and is a bishop pawn or rook pawn, and the bishop does not control the pawn's promotion square, the position is a draw. [55] See Wrong bishop . A rook versus a minor piece: normally a draw but in some cases the rook wins, see pawnless chess endgame .
The above is written for around ten pawns on the board (a typical number); the value of the rooks goes down as pawns are added, and goes up as pawns are removed. [ 48 ] Finally, Kaufman proposes a simplified version that avoids decimals: use the traditional values P = 1, N = 3, B = 3+, and R = 5 with queens off the board, but use P = 1, N = 4 ...
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its last rank. The player replaces the pawn immediately with a queen , rook , bishop , or knight of the same color . [ 1 ]
