I would like to improve in chess so I need some advice!

Is the four nights a good move?

For which side? It doesn't lose immediately but it seems not good fora 300 rated player. You need to stake out the center with one or more pawns.

I recommend you take the beginner lessons.

did that

1. I can do no more lessons   ︿_︿ 

In itself its not bad but likely transposes into other openings.  But if you are going to transpose into something, why not play it right away?

The 4 knights question is largely irrelevant. Both white and black are hanging material left and right. You could play the worst opening in the game and still be fine. Just wait for them to give away their queen for no reason. This is the problem to focus on. Neither side seems to be paying any attention to their pieces at all. 

TYSM!!!

I appetiate your advice!

I think that's enough of the four nights move

Let's talk about the king's indian defense!!!

Dont get me wrong but at your rating it is not necessary to study openings. I would just recommend to practice by playing games and not doing mistakes or hanging pieces. Even at my rating the most games are decided by mistakes and tactics that are overlooked. I personally like the King's Indian defense and i am sure that it is a decent opening. But to you i would recommend openings like the Italian or Scottish Opening if you really want to study or learn something what I would not recommend at your current rating.

First focus on learning basic chess instead of opening.You blundered e4 pawn in the opening,and multiple things in game.Learn one opening and some variations of it.Like King's Indian.After that checkmate patterns,forks,pins etc.If you know these you go up easily.You can add me and we play some games where I can explain you some of the little things I know and maybe you can improve a little bit.

OMG tysm!!!

No offence but do not study oppenings cause youre rating is too low just play some live games or you can play with bots if you want do some puzzles, drills then study oppenings

ok

Does anyone want to battle?

Don't fall into the common delusion that success at chess results from finding the "perfect opening system".  Some openings are definitely better than others, but beginners and novices should simply learn the general opening principles, and not worry about memorizing opening lines.  Studying tactics and endgames is a much more effective way to improve.

Since 90% of chess books are about openings, It's natural for novices to think that should be their focus.  This is partly the result of authors hyping their books as the "secret weapon" that will finally let you dominate your opponents, by either confusing them with your off-beat system.  Or by giving you the latest grandmaster twist on move 14 that your booked-up opponents haven't heard about yet.  But off-beat systems are off-beat for a reason (they're objectively inferior), and the surprise value really only works on other weak players.  And the booked-up opening arms-race approach is futile for players who reach the end of the book line, lack the chess skills to figure out what to do next.  I wish I could send this message to my younger self so that I did not have to learn this the hard way.

I don't think u answed le question
