the first thing a 1.e4 e5 must to is looking at the kings gambit. if you are ok facing the very sharp kings gambit (which will happen often) then its time to dig deeper into 1.e4 e5.
i recommend pickin a simple answer to the ruy lopez because you will not face it that often and when you does he usually plays an early deviation. for example i used a ton of time learning the marshall gambit but only got two marshalls that year and they were both antimarshallines declining the gambit.I play the berlin defence myself. despite no queens it leads to a complicated and sharp game where both players can win unless white play to avoid the berlin endgameline and goes for something more drawish which he actually often do but its still a game of chess where he can be outplayed. i know the berlin well and white cant sidestep it in a good way. this way you can forget about ruy lopez after a little preparation and start looking at the other lines white throws at you which is most of your 1.e4 e5 games
Apparently we all must play 1...e5 as a basic building block of our chess educations.
Yet they also tell us to not study opening theory in favor of tactics, endgame, and visualization exercises.
Therefore as I start playing 1...e5 I am tempted to find some kind of offbeat, little used, and non-theoretical reply to the Ruy Lopez to fulfull both these requirements, but if I did so, would I somehow be defeating the purpose of playing 1...e5 in the first place by not playing main lines?
What do you personally use against the Ruy Lopez and why? What are the characteristics of the variation you use against the Ruy Lopez, how theoretical is it, and how much do you enjoy playing it compared to other openings?
