gambit
Let an agent explain gambits and their logic, identify major gambits and countergambits with their main lines from opening references, relay their history and modern assessment, and distinguish true from nominal gambits.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain gambits and their logic, identify major gambits and countergambits with their main lines from opening references, relay their history and modern assessment, and distinguish true from nominal gambits.
A chess opening in which a player sacrifices material, usually a pawn, in the early moves to gain development, initiative or positional advantage, as in the King Gambit, the Queen Gambit, which is only nominally a sacrifice, the Evans Gambit and lesser-known lines such as the Brussels Gambit, with countergambits such as the Falkbeer Countergambit offered in reply; gambits were prominent in romantic-era chess and remain popular in club play and rapid formats.
What it is for: Trading material for initiative in the opening.
It can be explain the concept; identify major gambits; relay history and assessment; distinguish true from nominal gambits.
Distinguishing features
Early sacrifice
Initiative for material
Named lines
Engine-era reassessment
What it looks like
Not a physical object; move sequences on the chessboard.
How it is recognised
Opening with an early material sacrifice
King, Queen, Evans, Brussels and other gambits, countergambits
A sacrifice in the middlegame is not a gambit; the Queen Gambit pawn is usually regained
