Nimzowitsch Defense El Columpio Defense Intermediate (1.e4 Nc6 2.Nf3 Nf6 3.e5 Ng4) in Chess

“Nimzowitsch Defense El Columpio Defense Intermediate” is an intermediate-level sideline within the Nimzowitsch Defense family, defined by Black steering into the El Columpio-type pawn/piece configuration rather than the more common Nimzowitsch transpositions. However, the precise, widely-agreed move order that uniquely distinguishes the “Intermediate” version is not consistently documented in mainstream opening references, so I can’t responsibly give a definitive move sequence without risking confusion with sibling El Columpio variations.
