"... Every player memorizes. Grandmasters do it more than anyone else.
GMs spend most of their study time cramming analysis into their long-term memory. They rely on memory when they play their first dozen or so moves of a game. They rely on memory when they play 'exact' endgames. A typical GM has memorized a vast number of moves and key positions at both ends of the game. And this doesn't include the patterns and priyomes he amassed through subconscious memorization.
'Memory is very, very important,' said Roman Dzindzichashvili in a rare admission by a grandmaster. 'Actually it's one of the most important things for success in this game.' ...
... all good opening play is part memory and part understanding. ...
You begin every game by making moves that you remember are good. Inevitably there comes a point when you reach the end of your book knowledge. That's when your memory stops and the understanding is supposed to take over." - GM Andrew Soltis (2010)
we can have this conversation all day and night. some people here will still insist on sleeping with their MCO's and trying vainly to remember dozens of 20 deep lines..
What I'm finding is that at 1450, I can win games using 1100 level tactics (for real) by using a solid opening and good positional setup.....
It was very eye opening for me to watch chessnetwork's youtube blitz games (not his bullet games) commentary. I can't recall a single game of his many victories where he employed a deep 5+ move tactic to win. All of his tactics seem like 2, maybe 3 move rookie-1100 level tactics, but of course the key isn't the tactic, but the positional squeeze to create those tactics. That was really eye opening for me, and explained a lot of why I didn't make any progress for quite awhile despite studying a lot of tactics.
So you feel that studying tactics is OVER-RATED?
i don't think I can agree with you. I DO agree even in high level chess; tactics are usually Simple. but I invoke the "backyard professer" as an example of guy who doesn't understand chess NEARLY as much as he thinks he does.
even in Silmans several excellent book he admits (and proves in the amateur's mind) that rating is NOT strictly a matter of understanding imbalances.
the ability to calculate and to see tactical and strategic patterns is at the heart of a strong chess player (as well as less blundering and seeing winning attacks and neccesary defense).

look , here's is the way I see it- any given guys improvement is personal. I KNOW i have improved in chess. my rating is going up and I see more.
I don't read over master games and struggle to understand anything instructive when I have. on the other hand; I have solved Thousands of tactical puzzles. I am definitely doing better at the puzzles than I used to.
solving tactical puzzles might not be for you.
I wouldn't insist that it is the ONLY way to improve or even a NECCESARY part of improvement. I'm not sure capablanca ever did a tactical puzzle, but he sure did know his tactics.
doing lots of tactical puzzles has slowly helped me understand the important of "peice activity","open lines and diagonal" and yet these are sometimes considered concepts of Positional (or even strategic chess).

I don't memorize variations. and when I have done so, only the first several moves have been helpful. Studying Opening principles is Way important, though. knowing the names is useless trivia. do it only for fun.
sorry about the inevitable tl;dr.
I'd have to clarify somewhat as well. Studying tactics definitely is NOT overrated for beginners and those hanging pieces and missing easy kills regularly.
I do know, however, that my 5-min blitz rating here (I know, a poor surrogate of long-game ability, but that's all I have time for now) was stuck at 1150-1200 no matter how many tactics I solved. Chess literally seemed impossible to improve in, and the 1400s would crush me even before I had a chance to even THINK about a winning tactical shot.
I can now play 1400s even in 5-min blitz. Yeah, it's still a sucky rating, but it's a lot better than 1150-1200, and the key was absolutely not tactics, but to fill in the gaps of knowledge I had. Openings were a big offender since I'd avoided them, but my lack of ability to play strong endgames is (and continues to be) an equally problematic area.
I'm not at all lying when I say most of my games now won at the 1350-1450 range of rating rely on tactics that I could absolutely readily see instantly at the 1100 level. As I mentioned before, even NM chessnetwork's victories on youtube rarely rely on some monster tactic, but he still crushes and makes it look darn easy in the process by take care to setup a good position with lots of opportunities and by killing counterplay.
