Best opening for beginner

I think e4 is the best opening for beginners.

It’s the most popular move for everyone.

I love to fried liver

it depends on the person who plays the opening because all openings have disadvantages and advantages. For example we get the Italian game and it has the advantage of being reasonably easy, and is an opening that gives you different positions after it so that you can practice many positions, but the disadvantages are that the middlegames can be hard to play at times, can bait players to just doing the fried liver and not really learning, and at intermediate almost all players are prepared against it. What I am saying is that if you like the advantages and don’t mind the disadvantages much then the opening might be a good one for you and don’t forget about the style of the opening and if it’s not your style like for example positional style then it’s not for you unless there is another line that can’t go to your not preferred line in any way. I will say more examples of disadvantages and advantages. Advantage examples: easy to play middlegame and opening, is a system opening, gives different after opening positions to practice other positions, matches your style, and not baiting players into just trying to trap players. For disadvantages you have hard to play midgame and opening, doesn’t match your style, leads many players into just trapping people, and not a system opening.
