A gambit (from ancient Italian gambetto, meaning "to trip") is a chess opening in which a player, more often White, sacrifices material, usually a pawn, with the hope of achieving a resulting advantageous position. Some well-known examples are the King's Gambit (1.e4 e5 2.f4), Queen's Gambit (1.d4 d5 2.c4), and Evans Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.b4). A gambit used by Black may also be called a gambit (e.g. the Latvian Gambit—1.e4 e5 2.Nf3 f5 or Englund Gambit—1.d4 e5), but is sometimes called a "countergambit" (e.g. the Albin Countergambit—1.d4 d5 2.c4 e5 and Greco Counter-Gambit, an old-fashioned name for the Latvian Gambit).
