Alekhine’s Variation is a King’s Pawn opening where queen is brought into the attack of the black king initially. This would involve an attack as the black king side has not many major pieces in defense. Thus the attack might prove useful to certain extent though black still has sufficient defenders of the f7 pawn where the attack is at it’s peak.

The bishop and queen are quite sufficient to create a draw as the black’s king is also open and white too has enough counter attack.
