I am experiencing Antichess and it's more forcing than normal chess.
What are the best openings for white ? Is there any winning opening whatever the black does respond?
Antichess, according to Wikipedia:
Losing chess (also known as Antichess, the Losing Game, Giveaway chess, Suicide chess, Killer chess, or Take-all chess) is a chess variant in which the objective of each player is to lose all of his pieces or be stalemated.
"The rules are the same as those for standard chess, except for the following special rules:
- Capturing is compulsory.
- When more than one capture is available, the player may choose.
- The king has no royal power and accordingly: it may be captured like any other piece there is no check or checkmate there is no castling
- In addition to its normal promotion options, a pawn may promote to a king.
- Stalemate is a win for the stalemated player.
A player wins by losing all his pieces, or being stalemated. Apart from move repetition, draw by agreement, and the fifty-move rule, the game is also drawn when a win is impossible (such as if a dark-squared bishop and a light-squared bishop are the only pieces remaining).
