The Alatortsev Variation

White's P-Q4(d4) challenge supported 4.P-K5, confident of equality in any immediate P exchange.
Black develops his King's Knight to KB3(f6) to attack White's KP and avoid a possible 3..PxP, 4.QxP line. White may pursue for slight advantage or transpose back to regular lines. B-Alt.
