Here is a game where white (using 1.e4 e5 2.Qf3) at 2465 Elo plays black and 2184 Elo and gets spanked.
[pgn][Event "Open"] [Site "Pula CRO"] [Date "2007.06.24"] [Round "2"] [White "Dimitrov, Pavel"] [Black "Kozarcanin, Sead"] [Result "0-1"] [WhiteElo "2465"] [BlackElo "2184"] [ECO "C20"] [EventDate "2007.06.23"] [Variation "KP"] 1.e4 e5 2.Qf3 Nc6 3.Bc4 Nf6 4.c3 d6 5.h3 Be7 6.Ne2 O-O 7.O-O Na5 8.Bb5 c6 9.Ba4 d5 10.d3 b5 11.Bc2 c5 12.Nd2 Re8 13.Re1 Bb7 14.Ng3 Bf8 15.Ndf1 g6 16.Bg5 Bg7 17.Ne3 dxe4 18.Nxe4 Bxe4 19.dxe4 Qb6 20.Rad1 Nc4 21.Nxc4 bxc4 22.Bc1 Red8 23.a3 Qe6 24.Qe2 Bf8 25.Ba4 a6 26.Bc2 Nd7 27.Bb1 Nb6 28.Ba2 Be7 29.Be3 a5 30.a4 Rxd1 31.Rxd1 Rb8 32.Rd2 Qc6 33.Bxc4 Qxe4 34.Bb5 Nxa4 35.f3 Qb1+ 36.Kh2 Nxc3 37.bxc3 Qxb5 38.Qxb5 Rxb5 39.Rd7 Kf8 40.Ra7 Rb3 41.Bd2 Ra3 42.c4 a4 43.Bh6+ Ke8 44.Ra8+ Kd7 45.Ra7+ Ke6 46.Ra6+ Bd6 47.Bf8 Rd3 48.Kg1 f5 49.Kf2 h5 50.Bh6 a3 51.Ke2 Rd4 52.Bf8 a2 53.Bxd6 Rxd6 54.Rxa2 Rb6 55.Kd3 Rd6+ 56.Ke2 Rd4 57.Rc2 h4 58.Rc3 Kf6 59.Ke3 f4+ 60.Ke2 Kf5 61.Rc1 e4 62.fxe4+ Kxe4 63.Rc3 g5 64.Rc1 Rd3 65.Ra1 Re3+ 66.Kf2 Kd4 67.Ra4 Rc3 68.Ke2 Rc2+ 69.Kf3 Rxc4 70.Ra2 Rc3+ 71.Kg4 Rg3+ 72.Kf5 c4 73.Rd2+ Ke3 74.Rd8 c3 75.Rc8 Kd2 0-1 [/pgn]
So my conclusion is that we can't draw any conclusion from a single game.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

There's just no way 2.Qf3 is a good move. If it was then all of chess theory would need to be rewritten.

[Date "2007.06.24"]
[White "Dimitrov, Pavel"]
[Black "Kozarcanin, Sead"]
[Result "0-1"]

So my conclusion is that we can't draw any conclusion from a single game.
Yep. After 21...bxc4

[d]r3r1k1/p4pbp/1q3np1/2p1p1B1/2p1P3/2P2Q1P/PPB2PP1/3RR1K1 w - - 0 22

SF thinks White has an advantage of +1.85 (depth=31).

After 34....Nxa4

[d]1r4k1/4bp1p/6p1/pBp1p3/n3q3/2P1B2P/1P1RQPP1/6K1 w - - 0 35

SF's eval (depth=29) is
+2.89 35.Rd7 Bf8 36.Bc4 Nb6 37.Bxf7+ Kh8 38.Rc7 Bh6 39.Bb3 Bxe3 40.fxe3 Rf8 41.Rxc5 Qb1+ 42.Kh2 a4 43.Be6 Rf1 44.c4 e4 45.Rc6 Qd3 46.Qxd3 exd3 47.Rxb6 d2 48.Bg4 d1=R 49.Bxd1 Rxd1 50.c5 Rc1 51.c6 Kg7 52.Ra6 Kf7 53.Kg3 Rc2 54.Ra7+ Ke6


35.f3?? is the losing move.

White is so much stronger than Black that he outplays Black from an equal opening position, gets a winning position, and then makes a huge blunder to lose the game.

It's really hard to believe the Italian would be bad for white. White is up a tempo after all. As I see it the best line for black is to just play what Ding plays and play a5 instead of the usual a6 lines.

I always found funny how ppl can take mediocre games by some pathetic humans as a reference for something.
Essentially any correspondence game played before 2015 is crappier than what BF or LC0 can provide at 1min/move on strong hardware.
Huge databases are so irrelevant today. I understand that it's a hobby but putting so much importance on essentially useless things is just hopeless.

And yet Lc0 can be Tactically blind.
And yet SF can make opening blunders.
And these humans are roughly 2700.
The real problem here (for reference purposes) is that there are zero games between high end computer systems for this odd (1.e4 e5 2.Qf3 *) opening.

I agree with you that computers are better than people today. But that does not mean they cannot be the best available reference.
It is also true that no computer system is flawless yet.

Lc0 can be tactically blind but not about opening. And I specifically mentioned BF coz it is much stronger in opening than SF alone.
Problem is when it comes to unknown positions 2700 FIDE is useless. They are experimenting, fishing, looking for a surprise. Also, even if they play couple of moves correctly they'd soon start with blunders, much sooner than in known opening yielding any result totally useless.
If you really wanna explore the opening you need to play MC with strong engines and artificially introduce some randomness. There is really no other way.
