Chess Vision/Tactics

Hello all, I have a question that I think many of you are familiar with. I'm doing tactical exercises on a website and studying from Yusupov's first book. What I have realized is that I can calculate accurately for a couple of moves, but usually around moves 4/5 things get blurry. I already forget which pieces were where and my calculation gets quite inaccurate. 

I would like to know what I can do to improve my chess vision, if that's the right term. Obviously solving more exercises can help, but I would like to supplement it with additional methods/exercises. I would be happy to hear your suggestions.

Also, I was wondering if training for blindfold chess or coordinate exercises etc. would help. Unfortunately I don't know any good sources to do that. Chess.com and its main competitor have some drills but they are quite limited tbh.

Thanks for your answers,

That's a FAQ on this site. The consensus about blindfold chess is that blindfold chess is not particularly helpful for visualization, and might even be harmful. As for what *will* help, I don't know, but the standard response is for people to tell you to work a lot of tactics puzzles, which is a very unsatisfying answer to me.

 Hi Aetel, I am in a similar situation in learning the game of chess. What you are describing by thinking several moves ahead is often called "calculation"; where as " vision" usually refers to identifying where certain squares are (a1 bottom-left if you are white). This ability to "calculate" is surely helpful in chess, but not as needed as most beginners think. Most really good chess players can only "calculate" maybe three or four of their moves ahead. The key is not how far one can "calculate", but how accurate it is; I can follow forced lines for miles. However, as far as blindfold chess - I find that only really gifted people with great memory are great at this (although practice can still make you better). Luckily for me, I find this ability to mean little as I can always see the board in a game. To improve tactics, and calculating ability, I sadly find nothing better than simply playing actual chess games, and doing the chess.com tactics daily - more as a routine than number of problems. Although I do not play blindfold chess: I do often in OTB, or long online, chess games look away from the board. I do not stop thinking, but I find this to help me not only memorize the board, but also gets me to see things differently when I look back at the board. I think that the answer to most chess questions is to practice, as much as most do not like hearing this. I hope that you find my experience at least a little bit helpful. I will admit though, that I am curious to see what advice other people have on this forum - as I am in a similar position, wanting to improve. Many of my friends are much better chess players than me, but I find my thoughts accurate at those levels too. In my opinion: the biggest thing to take from this is that many great chess players only look a few moves ahead, but as a chess player improves - they will gradually be able to calculate farther ahead.
