Questions related to handicapping a player in chess
The handicap tag says:
Games with handicap to compensate for difference in playing strength. For instance "pawn and move" odds means the stronger player is black (move) and has f7 pawn removed (pawn) before the start of the game. "Rook" odds usually means the stronger player is white and has his a1 rook removed before the start of the game.These used to be common 100 years ago usually combined with gambling on the result but are much rarer today.
The odds tag says:
For questions about games where odds have been given or about giving odds usually to handicap the stronger player. e.g. "pawn and move odds" means the stronger player is black and has the f7 pawn removed before play starts, "knight odds" means the stronger player is white and has the b1 knight removed before play starts.
Should these be merged, perhaps making the ones that are removed synonyms instead? I don't see any difference between them.
