How can I improve chess visualization and calculation?

After 500+ blitz games your rating is 800...

That test is just a silly gimmick. I'm not trying to be mean, I'm just telling you the truth.

This is a good question.

The answer is beyond chess, and applies to any skill: 

Practice the thing you want to improve.

If you want to improve calculation and visualization then solve untimed tactics where you spend as long as 1 hour on calculation. When your visualization starts to get fuzzy, memorize the position, and start your calculation anew from there.

I've been playing chess for nearly 20 years and this beginner is telling me "it's less than you think."

You have no idea what "I think" 

Of course. We all start out that way.

Just saying.

You have to work more on having a partner moving the pieces on a real chessboard, you have to be blindfolded, play that way, at first it will be very frustrating, keep building up this skill until you can visualize the board and the position of the pieces, at least that is what I have read. I have been practicing, not as much as I should, but I have been able to calculate two or three moves ahead, sometimes even four, very rarely. Use your imagination, try to visualize the board with the pieces and imagine what move would your opponent make. Hope it helps you and others

You have to evaluate every move, and after a move is made you have to ask yourself. What changed in the position? It is very hard, I am still working on it, only practice will make you a chess GM.

I am pretty good at that when for example I am in a daily game with The "analyze" option where I can calculate variations by moving the actual pieces, but I fail to see it in my mind 😢

I have a problem with tactics and overall chess moves... I tend to find candidate moves instinctually within 5-10 seconds, and the first one I think of actually tends to be the correct move. I always have the general idea in my head as it pops up instinctually. However, I am rarely completely sure of the combination in certain kinds of tactics. I get lost in visualization and calculation after 4 or so moves when trying to solve a 1400-1900 tactic. It's kind of annoying as it decreses my confidence levels in risky tactics such as sacrifices, and also often gets me into time pressure as I spend more time attempting to calculate good moves. I think this has to do with my "chess personality" which is "prodigy". They say that people who are prodigies tend to be very instinctual. This can be a good thing in finding candidate moves I suppose... But I certainly do not like the fact that my calculation/visualization skills are low. So I was wondering If any of you have a solution to this puzzling problem?  

Thanks in advance.

Do push ups. This will help you visualize better. 

There are two things in chess that matter most. Positional sense and calculation ability. Alekhine was a great calculator whereas Capablanca and Petrosian were positional players. In my personal experience if you want to be a good chess player positional sense trumps calculation ability. You cannot get very far with calculation alone as there is simply too much to calculate. You have to have intuition of what kind of position you are atrying to achieve. Which pieces' dominance you are trying to increase. Which squares you are fighting over. What is ok to give in trade for what else. The famous story of Richard Reti in which he was asked how many moves ahead he could think he said 'one move. the best one.'
