Good Solid opening for PD4

Doesn't your school team have a tutor/coach who might be a bit more familiar with your games and ability, than some random people on the internet?

My school does, however i tend to ask everybody, so while im asking on the internet, i will end up asking them (if my memory does not fail me)

Thank you for the the recommendation, and the link.

You seem to have a better knowledge of Openings than tactics, judging by the fact you get about half your Tactics Trainer problems wrong.
I coached a very successful high school chess team and school club and I had trouble getting my players to focus on tactics until our club had a guess speaker, a National Master, who was asked what openings he favored. He shocked my players by answering that he didn't care what opening it was, as long as it allowed him to reach a playable middle game.
I see that when you mention those opening, you don't mention what middlegames they lead to. For example, my players often played French or sometimes the Caro-Kann against 1 e4 because they knew their success would probably be determined by how successfully they were able to play ...c5 and start a Q-side counterattack. Against 1 e4 e5 they played 2 Bc4, the Bishop's opening that had been out of favor for 60 years at the time and is still not heavily studied, knowing that after 3 d3 4 Nc3 5 f4 they were nearly in position to castle Q-side and storm their h, g, and f Pawns at Black's K-side.
To carry out such attacks, you'll have better success the better your knowledge of tactical and positional motifs. An encyclopedic knowledge of openings is good but less valuable.
Try to learn, know the names, and be able to demonstrate the motifs on the following interactive pages. When you do Tactics Training, here or at places like chesstempo, after each problem study the TAGs - identifying the tactics used, and ask yourself why you didn't see them sooner or learn them if you don't know them. Make sure you understand the difference among a Pin, Skewer, and X-ray Attack, the similarities and differences between similar patterns like the Dovetail Mate and the Swallow's Tail Mate, etc.:

If you have time, study the 36 games illustrating the four straightforward principles in Fred Wilson's Fred Wilson, Simple Attacking Plans, especially the one about concentrating on aiming all your pieces you practically can at your opponent's king and relentlessly attack.

Sorry for the late reply, thought i had already. Took me a while to realize i hadn't haha.
Thank you for the detailed reply, and although i have learned the moves, thats due to the computer playing them, but if we are being honest. Thats not a valid excuse...
Ill do as you suggested, and thankyou for suggesting them
I also found a pdf of the book online, and will run through the games on their as well. Thank you, again, for the recomendation.
Top of the morning to you all! My name is Declan, and i have another question for the day
(i typically prefer to add backstory to a question, skip the first 2 paragraphs if you dont want to read that part)
I
dont typically worry about openings, i just usually play whatever appears fun, and is solid.
However this time is different, im in high school you see, so must people are at the 800 range are so (which is where im at) State is coming up, and i like to build up any advantage i can manage. I am already working on tactics and such. But i feel i should iron this out as well. I memorized alot of random lines for fun, so... please dont think im focusing too much on openings, i spend almost no time on the opening.
Anyways on to the question! Whats a good solid opening for d4? Im not exactling meaning to memorize moves, just a opening i can wrap my head around and learn the ideas of.
The openings i do play are rather simple, I play the Petrov against e4, And I play D4 as white, i go into the queens gambit if my opponent plays d5.
If my opponent plays the Indian defenses, i play the orthodox way against the Kings Indian, i havent faced that in a tournament yet, but its what i play against the computer.
Against 2. E6, i play Nf6. Against the Queens Indian i play the Petrosian variation (4. A3) And In the Bogo Indian, i just offer the bishop trade.
I have never faced the Benoni, all i know about it is to push the pawn haha.
surprising how much you can retain when facing the computer!
Most of my games end up in a "Static Center" i think its called, based on googles definition, its 2 semi closed centers or 1 open file in the extended center. And its what i feel comfortable playing in. Not that it matters at my level.
Currently i have been playing the tarrasch defense in the queens gambit declined. However, I worry about its playability, it seems to give white a simple plan, not thats it hard to figure out as black. Just baseless worries about it giving me a slight disadvantage haha.
One more thing i should note, unlike my fellow beginners i tend to play less aggresive then i probably should, So i tend to shy away from gambits and related all out attacks. But thats a problem ill iron out another time! Instead of quick mates, i tend to go for more "positional" Ideas. (i put that in quotes, due to my rather newbness, what positional stuff that i know)
(that was probably longer than it should have been, definitely longer than i intended)
So, now all that information is out of the way. Do you guys have a solid opening i can look at for my state tourney? Id prefer to remain in the queens gambit area. Due to hearing thats the best way to improve. But im willing to hear other ideas
I do hope anyone can help me, this is something that i couldnt figure out well myself haha.
(i forgot to mention this in the post, so ill just throw it here, please dont look at my online games for an idea of my playing strength, i cant visualize the board, or even calculate well online. So i make alot of ridiculous blunders online. Its quite frustrating)
