Opening for defensive player

Hi!  I'am about 1600 chess.com now.
I'am quite an old man so I decide to begin opening study,
and strick with it for the rest of my time.

I begin chess with 1.e4 and It's okay.
But I feel that I often play defensive and don't do attacking in games, quite wait and counter-attack.

1. Should I go to study 1.d4 to be my main opening?

2. I heard much about Ruy lopez that it is very good to study chess.
Can defensive player play Ruy lopez?

3. Other advices are welcome.

Thank you very much.

As soon as I heard the word “defensive”, the stonewall system popped up in my mind immediately. The goal is to reach almost impenetrable pawn wall f4-e3-d4-c3(or f5-e6-d5-c6 if played as black), and just mobilise in the way of your opponent’s forces. It can be played as white against anything, and as black against anything except e4(for which I think caro-kann is the best fit, since it is pretty slow, has very solid pawn structure and is indeed pretty defensive. Other options are the philidor and petroff defences as black is e4-e5 positions, hippopotamus setup, maybe old indian setup with castling as well. I think that the first repertoire is the better fit anyway since it already covers everything

Thank you very much.
I will study your advice.
Now I'm studying London System.
I'll try stonewall next.

You’re welcome. I just noticed that i didn’t describe the stonewall correctly. Basically attacking your wall is a bad idea, so your opponent will try to play around it. You will mobilize in the way of your opponent’s play and hopefully win the flank battle

"I'am about 1600 chess.com now."
++ That is too soon to study openings. Study endgames instead.
"and strick with it for the rest of my time." ++ Yes, it is unwise to change openings.

"I begin chess with 1.e4 and It's okay." ++ 'Best by test' - Fischer

"1. Should I go to study 1.d4 to be my main opening?"
++ No. Defensive players like Karjakin, Giri, Karpov, Rubinstein... opened 1 e4 as well.

"2. I heard much about Ruy lopez that it is very good to study chess." ++ Yes

"Can defensive player play Ruy lopez?" ++ Yes. See the above players.

Thank you very much. tygxc.
It's interesting to know that.

I would actually recommend playing something like 1. g3 or 1. Nf3 if you prefer to develop quietly and counterattack rather than develop aggressively and attack immediately.
1. d4 and 1. c4 would be my next recommendations.
I wouldn’t recommend 1. e4 given that the more quiet lines in it tend to allow Black much stronger chances.
If you do decide to stick to e4, I would recommend a repertoire like so: 
Against 1… e5: the Anti-Marshall Ruy Lopez, the d3 Ruy Lopez (be it the anti-Berlin, Anderssen, Duras, Martinez, or Pilnik, I’ll link a post I wrote explaining those in detail), or the Giuoco Pianissimo Main Line. 
Against d6 Sicilian: Delayed Alapin with 4. d3 or 4. Qc2. 
Against e6 Sicilian: KIA, Westerinen, or Kramnik. 
Against Nc6 Sicilian: Rossolimo. 
Against French: the Tarrasch or Exchange.
Against Caro-Kann: the Breyer, Mainline, or Exchange. 
Against Scandinavian: 3. Nf3. 
Against Pirc/Modern: 3. f3 transposition to Saemisch KID. 
Against Alekhine: Exchange.

i believe in giving the most challenge to my opponent and making him suffer for his inferior opening choices. i would recommend learning how to pressure them and how to get the most advantage possible and understand where the advantage comes from.

Thank you @AngryPuffer
I have to think about it.
It is very impressive when I see someone play attacking chess.
I feel like every move has it's meaning.
Chess is quite very difficult for me. Thank you.

Thank you for your very detail. @Ethan_Brollier
I just have played a little Alapin with Sicilian, Giuoco Pianissimo with Italian.
The other advice is very new for me.
I'm looking forward to your next recommendations.
Thank you very much.
I also never play 1.g3 or 1.Nf3 .

Here is a famous defensive game with the Ruy Lopez:

if you like much more quiet games then ruy lopez would be a good choice. A second option that i think you would enjoy is the catalan, as it is known for being quite resilient and difficult to break as black.

Stonewall attack AND defense against everything BUT 1.e4, then carokann or if 1.g5... then just punish grobs for trying to be clever. LOL

Me? I DESPISE playing the stonewall straightjacket for as hard as it us for an opponent to get to you, its hard for you to get your pieces swinging too.

It's fairly simple to learn the basics. If your opponent tries to attack your QS, just close it off with pawns and follow the standard KS pawnstorm with all pieces plan and if he castles QS, throw all of your pawns at that with your much safer 0-0. If you like to defend, there's a reason it's called the STONEwall

I bet you have the patience for it that I don't. Even as a 1400, it was EASY to last 30 plus moves against wishy washy, loves to retreat for no reason fritz 6. I'd rather miniature myself

" I feel as though openings like the the Dutch (stonewall) are sort of like the prostitution of chess - you can get great positions and ratings points and fly around feeling like a champ.

But people will judge you for playing it. They'll talk about you condescendingly behind your back. They'll avert their eyes when you appear.

And you'll feel guilty deep down, knowing that what you're doing isn't quite right. That despite the quick rewards there's something sinister in it also, that you will need to give it up one day.

Imagine being 40 or 50 years old and still turning tricks with the the dutch - have some dignity and self-respect." -Uhohspaghettio1

also you aint getting past 1900 with the stonewall, people will figure out how to get better positions as the opposite color easily as there is a sort of refutation

lol not me, i still cry each time i see the stonewall

Calling stonewall chess prostitution is something that is fully unlogical…. I understand the vienna gambit or london system, but stonewall….

the refutation is so unlcear that i still dont understand it after alot of study, but i recommend you try to put some study into it

most often the computer just recommends taking simple precautions on your kingside then storming the queenside, but that can often be very tricky for black if he does not play accurately

Thank you. @AngryPuffer @lassus_dinnao @Chess_Player_lol

I have to read your post many times.
I played Stonewall defense about 2 times at my chess beginning.
I've heard that Dutch defense have risk because of pawn f5.
And we can't play Dutch in the higher level.
I don't know it's true or not. And I couldn't go to high level.
Now I'm studying London.
But I have search about Stonewall attack before.
I think I should study 1.d4 like Queen's Gambit.
And London may be more similar to QG than Stonewall attack.
That is my thought before this topic.
I will try to play some of the openings as your advices.
I think I will choose some in the end. And try to understand them.
Thank you very much.
And I like the name Stonewall.
