At what rating does the study of positional chess matter?

Said another way, at what rating would studying positional chess increase one's rating? 1200? Lower? Higher?

What about someone new to chess? After knowing the rules of play, should it be part of the first lessons with a chess teacher?

Who needs to study positional chess anyway? Chess is 99% tactics. Right? 😜

it all depends on how good you are, so if you study and get better than you get more points. hope this helps

Everyone who wants to play well should study it,

A solid positional player builds up very,very slowly gains more and more small advantages and space on the board he or she likes to squeeze and crush their opponent to death like a large python if you study the games of Karpov and Samuel Reshevesky you'll see this style of play is very,very affective they don't need flashy tactics to win.

Positional Players are very patient they wait for their opponents to fall on top of their swords and die a miserable death when they launch brash and wild counterattacks.

I got to 1547 USCF with just good old fashioned, caveman style chess but after that I hit a bit of a wall. And started sinking back down to the mid-1400's.  A few months ago I really got serious about studying more about positional chess and stratagy. And now my rating is going back above the 1500's and climbing.  So I suppose a good time to start working on positional chess is in the late 1400's to early 1500's.  

However, if you get a chess teacher then my advice is to just study whatever they tell you to because they usually know what they're doing.

It may not increase your rating right away, but it's always useful to work on foundational knowledge.  Even a beginner will find it useful to know about things like doubled pawns, development and king safety.

Of course just knowing about this stuff doesn't make you immune to the mistakes.  All the time you can find games of otherwise decent class players giving their opponent an attack on their king, falling behind in development, ignoring the center, having passive pieces etc.

If you can keep playing reasonable moves in between tactics then your opportunity for tactics will greatly increase.

I think  positional chess is rather harmful  at low(our) level.people should play muzio gambit and not mmic kramnik's slav games in online chess upto 20 moves.It's because we learn most from our faults and opponents fault and the most important part you will miss fun of attack and right defence.

People who miss a mate in 4 should never go to study  abstruct concept like  centraliztion  .

It will improve your ability at all levels.

Tactical oppurtunities are the result of good positional play

0 upwards.

The only problem will be if you make 'good positional moves' which fail tactically.

i think these distinctions between positional and tactical are illusory.

It's useful at any level.
