Question for more seasoned player.

How will blitz not help it?
Hansen played tons of blitz in his youth

I think blitz is counter intuitive to learning or improving. It forces you into a position where you are going to panic the moment you don't recognize a pattern or what to do against that pattern. I guess what you could do is go over  your games after you lose, but i don't see why you'd want to do that over playing a slower and more methodical game in which you come to the proper moves at your own pace.

GOOD THAT IM YOUNG AND QUICK IMPROVING.

Thanks for your insight.

 Blitz is great for openings.

A lot of people try weird trashes against my KID (I cant remember when was the last time I saw a freaking mainline on chess.com) or simply tricky and interesting sidelines. By playing blitz I can see tons of lines against my KID and prepare for them.

If I were to do that on slow games It would take me an eternity.

Also. Blitz is fun!!!!!!! Specially when your damn mouse betrays you 

Wow. that game was the biggest blunderfest I have had in days. I dont even know why I keep playing chess after stuff like that happens.

It was 3 min chess. And I had mousesliped the 1st move. I like to think Im not focus on playing well, it means im really not a patzer, but I play like a patzer when im not concentrated.

I did have to play c4. It is a french reversed and so I need to attack the center.

Im not a fan of blitz under 10 min or bullet chess yet. Maybe once I am more experienced.

To become a master (2200+) you essentially need to excel in all aspects of the game, opening, middle game, and endgame. How I've been doing it, is I started drilling openings, studying books, games of masters, reviewing my games with an engine. Now I'm working on learning endgames, and calculations and tactics in the middle game (positional stuff for middle game too). If you get good with openings you'll have a decent position in almost any game if you know the line. Start with that then move on to the other stuff. You can learn it a little, don't exclude it completely, but I recommend right now your focus would be to learn openings.

I can easily tell you why. I use to do coaching for bronze players in league of legends. Bronze players are probably  the equivalent of 1000 rated players and below in chess. They do not think before they move, the blunder a lot and tend to be pawn pushers or people who do not grasp the fundamentals. This is most commonly because they want to just play, play, play. They do not want to educate themselves with lessons, youtube videos or studying in any way shape or form. They do not learn from their past mistakes or put effort into improving. They will most likely self-improve if they stop playing blitz and start playing daily chess to slow down and look at the entire board. But it will be a long agonizing improvement over maybe a year (just to get to 1200),

When I coached LoL people didnt want to go into custom games to practice their god awful mechanics, they did not want to learn anything about macro-game and did not want to learn why their choices were awful. Their mindset is if I play enough games I will get better. It is the disconnect between experience and investing time.

Experience is knowing the correct choice because you have analyzed the events and determined the action that will gain advantage. Investing time is usually wasting time with no certainty that you will get a return on your investment.

Learn patterns  that masters use from games, if you apply them to yours at the right time it will help you a lot too. Try and also understand why they play the moves they play, analyze it.

 I have been doing tactics lessons with my membership here. I like the skewer and pin. I am gonna go over deflection and decoy tomorrow most likely. I have made a checklist that I go over for every move I make. Anybody know a tool that allows you to practice pawn breaks? That would seem to be super helpful. I understand how to use pawn breaks to break open a closed game, but that does not mean I am well versed or even decent at implementing them.

 "..., you have to make a decision: have tons of fun playing blitz (without learning much), or be serious and play with longer time controls so you can actually think. ..." - IM Jeremy Silman (June 9, 2016)

Hansen played blitz and bullet. AND GUESS WHO IS BETTER FROM THOSE 2, YOU ARE RIGHT BUDDY. OH YEAH

Also. What keeps you away from playing tons of blitz and also playing tons of long time controls?!

The thing I think Jeremy's quote conveys is that if you plan on investing time into playing seriously investing any amount of time into blitz games would impede your ability to learn and will engrave very bad habits into your play, due to the lack of time to think out all of your moves and play the correct moves. Habits are really easy to make and really hard to break. In almost every aspect blitz is counter intuitive for the serious chess learner.

Blitz develops intuition and opening familiarity faster than slower time control chess just because of a larger volume of games at a faster pace. Most other things would probably tend to improve with slower chess.

I do not think there is any evidence for this assertion. 

You might believe it.  It might seem to be true for you.  That does not make it true.  One problem with the Internet is the huge amount of opinion presented as if it were fact.

I am not sure how incontrovertible proof could be provided for such a statement, but I didn't come up with the idea myself. It is a fairly common viewpoint but from my memory I think FM Todd Andrews said blitz was useful for learning a new opening in one of his video lectures on this site and dzindzi said he sometimes prescribed blitz for chess players I am thinking for similar reasons. It is entirely logical that playing an opening 10 times and trying to remember how different opening moves influenced the game would help familiarize someone with an opening faster than 1 game with classical time controls. As you suggested it did work for me for a few openings, although that wouldn't qualify as any definite proof.
