Hi. I recently won this game https://www.chess.com/daily/game/272584850

All the chess variations I see online move the white Queen to E2 and not F3. Why? Why wouldn’t Qf3 be a good move?

There is a common trap for white with 4. Qe2, as shown below.

Furthermore, after 4...Nf6, Black is completely fine.
