white pushed too many pawns in the opening instead of developing their pieces. They didn't quite follow every principle

You cannot follow every principle

I think the term "guideline" is very fine. For not too advanced players it is good to have something they can hold in their hands like a rope to guide them. And if you have a look at the more advanced openings, mostly these rules are not broken in total. So, if I come into an opening I don´t know really I still follow these rules. It is not really important if a 700 Player or Lasker said it, because they are good. To look deeper, you must know more and then you come to absolutely the same problems: I.e. you learn the "Guideline" that you should start your attack in the direktion where your pawn chain goes. It´s good to know it, it is better also to know when you have to ignore these guideline.

Ah, and if somebody think when a Master is not following these guidelines he knows exactly why and has his good reasons to do so, have a look at the so called "Game of the century" where a strong master moved a piece twice in the opening and was destroyed by B. Fischer, who was 13 at that time.

The real question is :- Do the 5 opening principals know the 5 opening principles?

The Question is:  Who are you - and if so, how many?

@chesshypermaster : Here are the 5 opening principles that you must follow!

also @chesshypermaster :

Moving a piece twice is sometimes okay e.g. retreating a bishop when attacked by a pawn during Ruy Lopez.

Moving your queen out too early is bad, but early-ish can be a good thing. Your queen and bishops are your early game long range 'snipers', if there is an open path let the three of them work together. Letting your queen stay behind is usually for defensive purposes e.g. defending a weak square.

Finally, while it is good to castle early, don't let it become 'meh, I don't know what move to play next, so I'll just castle'. When you could just delay castling and do a pawn break, force a trade elsewhere etc for a bigger advantage.

Finally, I would add this: try and link up your pawns, don't let them be isolated. Isolated pawn = easy capture = a breach in your defensive wall. Even a couple of paired up pawns, one defending the other, is good.

if you do not castle here, you will lose a queen.

oh

im new in chess ok?

Yes, that is perfectly fine. But maybe you should be a bit more careful with such statements....

@JackRoach His national rating is 2875, though taking a look at his games mostly undermines the value of that statement.

You forgot the sixth opening principle:

"Always give check. It might be mate."

"Nobody ever died from a check."

7. play h4 h5

#8. Don't get checkmated

Bruh if his national rating was 2875 he would be well known. You can easily edit your national rating yourself on your profile. I don't need to teach you to not get fooled by fake info on the internet

Also I don't think a 2875 plays like this
