Nimzo Indian Defense Three Knights Variation Attraction in Chess

In the Nimzo-Indian Defense, Three Knights Variation, the “attraction” motif is a tactical idea where one side deliberately lures a piece (often the c3 knight or a central pawn) onto a square that enables a follow-up win of tempo, material, or position. A defining feature is the active pressure created by the Nimzo setup—typically with …Bb4 and rapid piece play around the c3/e4 complex—so that the opponent’s response to the lure becomes the key tactical trigger.
