rather optimistic, don't you think? That's basically the position that all classical white openings hope to achieve, and all classical black openings hope to prevent.
e4/Nc3/Nf3/d4
Any threats concerning . . . what? Typically 1.e4 gets a response of 1...c5 or 1...e5, both of which prevent d4 (or at least, keeping d4). But 2.Nc3 and 3.Nf3 is usually good (if likely to be boring). You can look into the Halloween gambit if you want to spice things up.

The most reasonable opening this happens in is the probably the Pirc defense. Black freely lets white take the center.
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Nc3

White played the same 3rd and 4th...
I don't like 4.Nf3 there, would rather play 4.Be3 or 4.Bg5

"Reopening" or "necroposting" a 12-year-old forum topic, which is generally discouraged, can be done for several reasons, but it often raises concerns.
Here are some reasons why someone might do it:
Seeking closure or sharing new insights: Someone might come across an old thread dealing with an issue they've also faced and might want to share their solution or ask if the original poster ever found a resolution.
Adding relevant information: If the topic is still relevant, a user might have new information or updates that could be valuable to others who might find the thread through a search.
A lack of newer or comparable threads: Sometimes users may feel it's better to add to an existing discussion, even if it's old, than to start a duplicate thread.
Bringing a topic back into discussion: In some forums, necrobumping can trigger a renewed conversation if the topic is still interesting or unresolved.
However, many forum users and moderators consider necrobumping bad etiquette, and there are several reasons for this:
Shifting focus from new discussions: Bringing an old thread to the top can distract from current conversations and overwhelm users who follow posts by date.
Irrelevant or outdated information: Old threads can contain information that's no longer accurate, and adding to them can make the overall discussion harder to follow.
Potentially triggering discussions with inactive or absent users: Many old threads are abandoned, and replies to them may go unanswered.
Spam: Some users, especially spammers, may target older threads because they are less actively monitored.
While AI-generated content can be used to reply to old threads, as indicated by the mention of a ban on machine-generated content in one submission, this doesn't automatically mean that every instance of necrobumping involves AI or is solely done for spam. However, concerns about the use of AI in generating forum content do exist, particularly regarding transparency and authenticity.
Many forum platforms and communities have rules against necrobumping, especially if the new post doesn't add significant value to the discussion. In some cases, old threads are automatically locked after a certain period of inactivity to discourage this.

Yeah - A Few things:
Post #14 - Was Nice Response
Post #15 - Had Errors
Post #16 - Had Errors
Post # 17 - No one cares

As far as this Thread goes, The OP Original Question was never Answered!
The Answer to the Question was Simple:
“Depends on what Black does!”
The moves White does can be very good or they can be very bad.
All of which depends on how Black plays.
2 Examples to showcase my point
White moves are completely fine in the above position. We can even call them Perfect!
In Fact, Millions of chess games have reached the above position!
The above position is totally trash!
Black should have lost his Queen, but White continued with his Auto Pilot moves.
Now, Black is up a Rook - Totally Winning!
Perfect examples of how White 4 moves regardless of what Black plays can be Completely Brilliant or Utterly Terrible.
——————————————
In the end, We circle back to what I said!
White 4 moves can be Good or Bad - All of which depends upon Black.

The phrase "Any threats concerning . . . what?" is a common setup in chess openings. Typically, when white plays 1. e4, black responds with either 1...c5 (the Sicilian Defense) or 1...e5 (the Open Game), both of which aim to control the center and prevent white from playing d4. White often follows with 2. Nc3 and 3. Nf3, which is a solid, albeit sometimes considered dull, approach. If white is looking for a more aggressive option, they could consider the Halloween Gambit.

Good Opening or not?
The opening sequence 1. e4 Nc3 Nf3 d4 is not a standard, well-regarded opening in chess. While individual moves like 1. e4 and 1. d4 are popular, the specific sequence is considered somewhat awkward and less optimal. It can lead to a variety of transpositions, but it doesn't have a clear, established plan or advantage for White.
Explanation:
1. e4:
This is a very common and strong opening move, immediately claiming the center and developing a piece.
1... Nc3:
While not inherently bad, Nc3 is not the most natural development for White after 1. e4. It can lead to the Vienna Game, which can be solid but doesn't offer White a clear advantage.
2. Nf3:
This is a standard developing move, but after 1. e4 Nc3, it can lead to various transpositions, such as the Four Knights Game.
3. d4:
This is a common move in various openings, but after the previous moves, it might not be the most effective way to develop White's pieces. It can lead to the Scotch Game, which has been analyzed extensively.
Black's Response:
Black has numerous reasonable replies to these moves, making it difficult for White to maintain a significant advantage.
Why it's not ideal:
Loss of Tempo:
Developing the Knight to c3 before d4 can be considered a loss of tempo, especially if Black doesn't play into the anticipated lines.
Lack of Flexibility:
White's options are somewhat limited after Nc3, and it might not lead to the most dynamic or advantageous positions.
Black's Counterplay:
Black has many opportunities to challenge White's center and develop their pieces effectively.
Alternatives:
White could have played 2. Nf3, followed by 3. d4, which is a more standard approach in the Scotch Game.
White could have played 2. d4, leading to the Scotch Game.
Alternatively, White could have chosen to develop their pieces in other ways, depending on Black's response.
In conclusion, while the moves are not illegal or terrible, the sequence 1. e4 Nc3 Nf3 d4 is not a highly recommended opening for White due to its lack of clear plan and potential for Black to equalize the position relatively easily..
