tabiya
A position in the opening of a game that occurs after a sequence of moves that is heavily standardized, and from which the players have many possible moves again.
This position is a real tabiya. It frequently arises from the Queen's Gambit Declined rather than the Caro-Kann […]
Where it comes from
From Arabic تَعْبِئَة (taʕbiʔa) or تَعْبِيَة (taʕbiya, “mobilization, arrangement”).
