You should compare chess to basketball - if you don't have the right talent or natural ability, no amount of training will make you a grandmaster.
Absolutely not true.

This means that if you work very hard at your craft, then you can become world class in something.
It doesn't mean that anyone can be a professional NBA player or chess GM. That's a ridiculous notion.
When Michael Jordan tried baseball, he failed miserably. He wasn't cut out for baseball - not a question of hard work, which he'd always done.
You are wrong,
I've been a professional french horn player for 20 years who has played in many of the world's premier orchestras. I can absolutely guarantee you that hard work overcomes most obstacles.
If you think this is not true, then perhaps you need to reevaluate what you define as hard work. The perception of hard work varies considerably from person to person.....
OK sure You have no talent in the french horn then?
This may as well be some 6.5 foot basketball player saying "I work hard, and that's why I'm in the NBA" to a 5.5 foot person, telling them it's remotely plausible.
Your argument proves nothing since you have no idea how talented you are in French Horn (which I'm betting is pretty talented, if your claims are true).
For instance I was reading about the polgar sisters and how only 2 of the 3 became grandmasters. Why didn't the third become one as well if its all about hardwork and training? Did the father fail in his experiment if only 2 of 3 became grandmasters? I for instance am struggling with chess I am just making so many blunders and have no gameplan after making a few moves in the opening. I hope I can become rated 2100-2200 eventually so I can reap the full mental benefits of chess.
I think this thread is drifting more to who can become a GM than in answering the original intent of the question: "I for instance am struggling with chess I am just making so many blunders and have no gameplan after making a few moves in the opening. I hope I can become rated 2100-2200 eventually so I can reap the full mental benefits of chess."
Considering your rating is under 1000 right now, I would look for gains in smaller increments before thinking about 2100-2200. I think you need to see more patterns, aka Tactical Motifs (a great list is here: http://chesstempo.com/tactical-motifs.html) and maybe study the general principles first to get your rating jumping. Then you'll be standing higher on the "mountain" and you'll be able to identify what else you need to go higher.
Personally, I have 2116 USCF correspondence rating - from the 1970's when you couldn't use computers to cheat - and, if given 3 days/move, I can recall enough theory, strategy, tactics, etc. to play a d@mn good game. But put 10-15 minutes on the clock and I don't have enough time to put together a solid plan, I miss tactical patterns - sometimes including easy forks or mate-in-3's, and often have to play "hope chess" to stay out of time trouble.
I've returned to chess after a long time away, and tried to assess WHY I have these weaknesses. A lot of it is tactical weakness. If you can't recognize a lot patterns QUICKLY it takes you longer to realize which moves to start evaluating. As IM Danny Rensch says in his patterns "...you should know" videos here, if you smell smoke, there's probably a tactic you can use in there somewhere. Recognizing patterns helps you "smell smoke."
And if you can't recognize the tactics available, how can you decide on a solid strategy/game plan? Finally, one -definitely including me- can develop bad habits of the mind, especially when playing only less than 30 minute games where developing a depth of thinking isn't easy. Someone showed me Dan Heisman's A Guide to Chess Improvement: The Best of Novice Nook. It has a great, 70 page chapter on Thought Process and then an 18 page chapter on Time Management. I ordered it from Amazon the next day.
So, for my foreseeable future in chess, my middle name is "Tactics." I hope to improve on tactics and how I process them in my mind. Eventually, we'll know if it helped!
