This is not an illegal move. It is called "en passant" and is entirely legitimate.

Hello Chess.com,
I have been seen many times that when we move pawn from its initial position to two position forward , pawn will be shown as two position forward in my display but it will be shown as single position movement is opponents system, i have experienced in both side, to me and my opponent also felt same. SO it entirely changes the game and plz take necessary actions to this error.Its been shown so far in Pawn's First movement only , not always only sometimes, but those are at crucial times. hope u got it. if any proof is need plz check my game with Stasys1950 and check the movement 28. Hope u will take necessary corrective actions. Thanking You
