e4, e5

No, Bf2 don't wins for black. 6. Kf1 will lead to a white advantage and even K:f2 is not lost for white. Ke1 is blunder that looses.

One Qe2 white is again in trouble

It is simply nonsens to comment N:f7 -+. I would never declare a position lost for white that stockfish likes to play cause of + 0,7 for white. If you estimate any position you should have very serious reasons to give a comment where stockfish thinks something completly fifferent. During a game all you have is your own judgement. If it is not according to stockfish - welcome to the real life of chessplayers, we all don't have the powers that stockfish has.
But when commenting, giving a line. then it is time to get serious. Why do you believe to judge the position better than stockfish?

sorry, but this study isnt helpful even at my level. you can catch players that never analyze their games, but thats it. its almost like playing the stafford (sorry, eric!). 4. Ng5 is hope chess (when you expect followup like that).

€: sorry i just clicked through first chapter, but it didnt entice me to go through the rest. those lines seem unrealistic. i am sure this will give plenty of better resources:
