Overview

Semi-Slav Defense: Anti-Noteboom, Stonewall Variation, Portisch Gambit is a gambit, classified under ECO code D31 within the Closed & Semi-Closed Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.

The Closed & Semi-Closed Games group covers closed and semi-closed games — 1.d4 systems characterised by long strategic manoeuvring rather than early tactics.

It is reached after 9 plies of play, with the move sequence 1. d4 d5 2. c4 e6 3. Nc3 c6 4. e3 f5 5. g4.

It is a variation of Semi-Slav Defense: Accelerated Move Order, which itself descends from the root opening Queen's Pawn Game.
