The Kramnik-Shirov Counterattack arises after 1.c4 e5 2.Nc3 Bb4 in the English Opening. ECO code: A21.

Overview

Named after former World Champion Vladimir Kramnik and GM Alexei Shirov, this aggressive line sees Black immediately pinning the c3-knight, echoing Nimzo-Indian Defence ideas. Black threatens to double White's c-pawns.

Strategic Themes & Plans

Black aims to disrupt White's pawn structure and maintain the e5-pawn as a strong central point. White can play 3.Nd5, 3.g3, or 3.Qb3 to sidestep the pin. The resulting positions are dynamic and offer chances for both sides.
