The Korchnoi Attack arises after 1.d4 f5 2.h3 in the Dutch Defence. ECO code: A80.

Overview

Named after Viktor Korchnoi, who employed this waiting move. The h3-pawn prevents ...Bg4 and prepares a flexible development scheme.

Strategic Themes & Plans

White delays commitment to a specific setup while making a useful prophylactic move. Black should develop normally with ...Nf6, ...e6, and ...d5 or ...g6. The position typically transposes into standard Dutch structures with the slight nuance of h3 already being played.
