You'd better be 2500+ before you become a professional. Very few people in the world manage to be one.
i wanna be a professional player . please help me

If the OP is serious my first suggestion would be to get out of Iran and move to Europe. If you have what it takes to become a chess pro Europe is the best place to be to achieve that goal.

However, if you think 1700 and 2000 ratings are professional level you have a very rude awakening coming...

I am a teen too and I started chess with group lessons. Once ur pass the 1500s you should take private lessons .
TBH professional players are the ones that make big money from chess. And to be at those level you need at least to be 2500.
I'm not a very good player and also not a bad player . im a teenager boy .
This is all the information you need to know that you may as well choose a different dream.
Chess, like tennis, is one of those pastimes where if you're not already one of your country's finest participants by the time you're a teenager, you're simply never going to improve enough to catch the teens who already are.

He isnt trying to become his countries finest participant WhatCheck
He is just wanting to be a professional player.. which IM is good enough for I think.

An IM is in the 99.75th percentile. If you're "ok" in your teens, it's not happening. It might have in the days before people were training with Rybka from the time they were in their cradles...before anyone with an internet connection had access to games against master level players 24/7/365...before the era when databases and Amazon.com made sure the sum total of all chess knowledge possessed by mankind was available to anybody willing to look for it.
But today, the best players are uncatchable if you don't take the game seriously till your teens.
He could probably hit expert status. But that's about the best to hope for.

You could be a professional poker player instead, same type of critical thinking involved, except there is actually money to be made. Hell, you could be a pro poker player online even :D
There are actually a surprising amount of ex-chess players that play poker for that excact reason, every year when I watch the WSOP at every other table the commentators are saying, "Well so and so made the switch to chess once the bills weren't getting paid and now is eliminated in 504th place winning $25,027.
That's not even a joke, that's how much 504th place won in 2009, and it goes up every year..... But that's playing tourney poker, which is a tiny stretch, but still more likely than pro chess. Could always just play ring games and the occasional small tourney and live quite comfortably.

i`m not a 1700+ player and i`m 12 years old . I know some ways to improve your rating.
1.Every day play 10+ unrated live standard chess games against different strong opponets (against players stronger than you by 100+ rating points)
2.Every day solve more than 10+ hard chess puzzles.
3.You should look for some fide tournaments
4.Every day for 3 hours you must read chess books (master games book,openings)
5.play in many vote chess matches
6.you should know 6+ good openings (with the all variations)
7.you should have a good coach and practice chess with him 4 days in week daily 3 hours
8.don`t forget to have fun if don`t have fun by practice chess you will not be able to be a strong chess player

People that talk about poker never mention how much the " buy ins" ( entry fees ) are for big poker tournaments nor how much many people have LOST playing poker, I wonder why that is ?

lol! Used to be 10k for the World Series of Poker. If you're at the table for half an hour and you can't spot the sucker....
I agree with both of rebs post. But seriously i would only do puzzles and read books. I mean videos are nice but its much easier to remember what you read, even if its harder work. I still can recall stuff, i read in capas books(nearly 10 years ago??)about how black need to take of the c3 knight to not lose. Same goes for puzzles, but i have a really really hard time remembering stuff from videos.

Alternatively, you could just turn pro now. Quit your job and just play chess full time. You won't have any money, but never mind at least the ambition is realised :)
Seriously though, what some people don't realise is that 2500 GMs just about scrape by playing chess, or if they do make decent money it's from coaching or writing books rather than playing. 2650+ to make a lot of money from the game, and even then it's nowhere near the huge salaries you see in a lot of professional sports.
To put those ratings in context. 500 elo points is about a 99% expectancy. A novice is rated 1000. An average club player, rated 1500, will beat the novice 99 times in 100. An expert, rated 2000, will beat the average club player 99 times in 100. A 'weak' GM, barely strong enough to play professionally, rated 2500, will beat the expert 99 times in 100. That's how good even the lowest rated rated professions are. Frightening.
I'm not a very good player and also not a bad player . but I wanna be a professional player . I love playing chess . im a teenager boy . please help me . say what should I doing for beeing a professional player . I should read books or solve lots of puzzles or see movies or ... . whats the best way to be a professional player ? At first I didnt know what should I move at the begining of the games . but now i know . playing lots of games is its reason . and if you are a professional player , say what did you do that now you are a professional player . (If your rating is more than 1700 , you are a professional player . but more professional players ratings are more than 2000) .
