Nimzo Indian Defense Three Knights Variation Intermezzo in Chess

In the Nimzo-Indian Defense, Three Knights Variation, the intermezzo is a tactical “in-between” move that forces the opponent to respond before you complete your main plan. A defining feature is that after the usual Nimzo setup (…Nf6, …e6, …Bb4), you insert a move that changes the timing of White’s central or piece development—often by hitting a key square or creating a threat that compels a concession. For an intermediate player, it’s about using tempo to make White’s next move less effective than it would be otherwise.
