Oh was this our game??
2nd opening move h4?

@1
"I don't understand the purpose of that move." ++ It has no purpose.
"disparages a similar move and stresses the advantages of controlling the center" ++ Yes
"h4 is good. It is a fair move" ++ White can afford it.
"What would be the reason for such a move?" ++ None really.
In a recent game,my opponent (white) opened with e4.
I (black) responded with e5.
White then with h4. I don't understand the purpose of that move. In the Opening Principles / Fundamentals lesson, the narrator disparages a similar move and stresses the advantages of controlling the center. Yet, on review, the engine stated "h4 is good. It is a fair move" What would be the reason for such a move? Thanks!
