How to calculate long variation in chess?

How to calculate long variation in chess? 

Youre an 1100 blitz player.  Work on the basics first.

I am not a beginner !!

I have defeated 1800 rated computer! Check this https://www.chess.com/analysis/game/computer/1620929

Reading comprehension is another problem.

“If I move here…. Will they move there?”
Many believe that masters are good at chess because they calculate deeply; the opposite is true. Masters consider fewer potential positions as they see more.
Practice getting a sense of position, build an intuitive form of knowledge by examining a great variety of chess positions… study tactics and solve puzzles.
Mangus Carlsen once said, “I see the best move almost instantly. I then have to evaluate my intuition.” or words to that effect.

thanks

Kotov wrote a book "Think like a Grandmaster" about this.
He knew what he was talking about:

My best piece of advice to you is to play puzzles regularly. You can start with specific themes such as mate in 1, then mate in 2, then pins… etc. Puzzles have helped me more than anything else in my chess career. 
Another thing that will help you a lot is Dr. Wolf app. Play games against him then “Train” with him. He will help you improve your calculation and retry your mistakes. This is also another great tool that helped me cross the 1400 rating barrier last year and eventually reach around 1600.

Another thing I love doing and is also good for calculation skills is watching chess events. Commentators often spend time analyzing positions and calculating different variations. This is the third most useful thing I have tried.

As a general rule, the more positions you’re familiar with, and the more patterns you can recognize, the easier calculation will become.

I wish you the best of luck! 😃

The question was "How to calculate long variation in chess?" not "Looking for personal guidance, what should I work be working on?"

Puzzles are not the same as calculation. Doing puzzles can help you to improve your calculation ability but puzzles are often more about pattern recognition than doing long calculations.

Practice visualization skills helps. There's a chess factor YouTube series starting with this one https://www.youtube.com/watch?v=WChrD2tXiWQ and the magnus trainer mobile app has a mind mirage game that is useful for improving your visualization.

If your visualization skills are still holding back your calculation ability after a lot of practice, then another option is to play correspondence chess, where you are allowed to move the pieces around before deciding on your next move.

@haiaku also makes an important point about evaluating the position correctly, which is another skill that gradually comes over a long period of time with lots of practice.

Finally, this is a decent 101

Basically you have to... calculate a lot of long variations! You have to train your visualization skill. Mohamed's advices are very sensible. I add that you can try to play blindfold. I still use to do it sometimes and it improves your ability to go deep and calculate fast. But as other said, this will not get you very far. I know by experience that I can go quite deeper than many stronger players, but most of the times we have to calculate just 2 moves ahead and then correctly evaluate the position. This is an art, even if you konw the basic principles and typical plans. Many times we are so confused and focused on what plan to carry on, that we do not calculate at all, and blunder horribly, even with plenty of time on the clock! Furthermore, when you know how to evaluate the position correctly, you know better which lines deserve calculation and which not, as Jack_Irish points out.

Yes but Magnus Trainer was not free for all. Is there any app that free for all?

In a daily game format, you are able to use an analyzer tool to go through many different lines. I think it is a great tool to use so you can play out many different combinations that you and your opponent may play. If you want to do it offline, there are a lot of sites and tools to go through line variations on the internet.

Long variation requires a firm understanding of basics. Even a trash player like me understands. Granted I'm just now picking up chess after 20 years. Your best moves in chess are usually the most obvious ones. Most players do not see.

It keeps on changing as you move higher up the rating. I don't want to explain but what I want to say is that I too have not mastered it.

Puzzles (tactics) are easier to calculate since they are forced lines of play. 

As for learning how to calculate "long lines"?  That depends on the position, and if its even needed, and the ability of the player.  Ask pretty much any Master, and they will tell you that having to calculate long lines isnt needed much.

Owh thanks for the information

This is a question I have been asking myself as I have played chess for many years since I was 12 years old. What I used to do was the simple, if I move here they might move there so I should do x instead or I should do y. As I read move books and bought more chess videos etc. I think the best idea is checks captures attacks. I started to play puzzle rush and just puzzle in general and what I notice was to solve the puzzle even the 2400 rated puzzles it came down to looking for checks captures and attacks. The second part of finding candidate moves and calculating is calculating variations. The reality is you should calculate all the promising forcing moves first finish off with all the promising attacking moves then activity moves. A Gm recommend when you study to get a notebook out and annotate your study games not your live games. Look before you leap by asking your self in this position which moves give checks write them down which moves give captures write those down which moves gives attacks and write them down. Then you play your opponent side and ask yourself the same questions you asked for your side what the best checks captures and attacking moves look down those lines and give them evaluations. what will happen is after a few weeks you will get faster at calculating and you will know why certain lines are bad. Its a slow process only do this when you are studying your games or Gm games.
