This game shows how one pawn and move order can drastically change a game

 that was a good game, the most important thing, I think is that the black king got the oppositon on the 2 & 3 ranks freeing up the pawns for advance.

8.Bd5?  good moves were 8.Nc3,c3 or 0-0

24.Qxg3? correct move was fxg3-double pawns is not good to have, but in this game correct was fxg3, white could not allow to black's queen- (e2)
