Mastering the Ruy Lopez

Don't expect some ideas here to make u understand this opening.
Too much material, u have to get a book for that.

I am preparing this opening. Can someone give me some ideas how to play while fully mastering this openings. I checked some masters game but i cannot understand.please give me some information.

In some ways, the Ruy Lopez is very easy to understand. White intends to pressure Black's centre pawn, force a concession and then play c3 and d4, dominating the centre. From there, White plays based on how Black responds, and White typically plays on both sides of the board.
Of course, in others ways, the Ruy Lopez is incredibly hard to understand., where an ill-timed exchange can come back to haunt you 20 moves later, and a single misplaced piece can lead to strategic ruin. I don't pretend to understand this opening, and I've tried to play it many times.
There are few resources that explain the Lopez from White's perspective in any accessible way. The best is likely the McDonald book mentioned earlier.

Look at the games of the top players and see how they play the Ruy Lopez.
Good player to look at would Karpov

let me show you some ideas for white and ideas for black. please note I am only like 2028 on the live ratings, so don't take this advice too seriously.
one of the main ideas for white in ruy lopez is to move the knight to g3 and then f5. now black has several different defensive ideas from here

Hey there snakey77 - just wanted to let you know that you post is certainly useful and appreciated (and it comes up in the first few results of a google search for Ruy Lopez typical ideas, so many others will learn from it too
The Schliemann-Jaenisch, 3...f5, is best, black gets fully equal at around move 25 or so.
Lol so why nobody plays this line at 2600+ level?
Because it is extremely tactical, and top players, just like everyone else, like getting
their play in familiar systems.
With the Schliemann-Jaenisch, it is constant tactics, similarly to the Traxler Gambit
of the Two Knights.
Who is playing the Traxler on top level?
I have seen many theoretical books, where 3...f5 gets !?, so more good than bad, but it is very difficult
to investigate until the end.
I tried to do that with Stockfish, and am getting fully equal in all lines quite soon, but of course,
I might have skipped something.
