Bird Opening, From's Gambit

From’s Gambit appears when Black answers White’s f2-f4 advance by moving the e7-pawn to e5. In algebraic notation, 1...e5 marks Black’s first reply and x marks a capture. A gambit is a voluntary investment of material, usually a pawn, to gain time, active pieces, or open lines. Here Black offers the e5-pawn and exploits the fact that f4 has removed part of White’s natural king cover. If White accepts with fxe5, Black commonly replies d6. After exd6, Black’s bishop recaptures on d6 and enters the game quickly, pointing toward the kingside, the half of the board where the kings began.

Black's compensation is not immediate pawn recovery but development and threats. The queen may reach h4 in some lines, the g8-knight can develop to f6, and the c8-bishop may enter the game while White's king is still on e1. White needs Nf3 and complete development rather than trying to keep every pawn while leaving the king exposed.

Accept, decline, or transpose

White may accept with fxe5, decline the offer with another move, or answer 2.e4. The last choice reaches a King's Gambit position through a different order. Reaching the same position from another opening is called a transposition. This possibility means both players should understand the structure rather than memorize only the opening's first name.

From's Gambit does not produce a forced attack if White defends accurately. It is a sharp choice that exchanges a pawn for development time. It resembles the Staunton Gambit visually, but there White sacrifices e4 against the Dutch Defense.
