It is a indisputable fact the Chess is however an unique game, that has been around for thousands of years. For me chess isn't just a mere "game..." it goes beyond that.
Why Chess is a Waste of Time and Intelligence – Yes

Chess exercises my blundering ability so that in life I will know both how to make blunders and how to deal with them after I have made them.

Some studies already showed that people with very high IQ have a hard time adapting to society as most of the people do. Issac Newton was a great example, totally bright person who cannot even have friends or enjoy a social gathering.
I think that's the case for those legendary chess players as well. Everything in excess is bad even intelligence. I'm considered myself a fairly intelligent person but i'll never trade my current state for a super high IQ because i know that it has its price.
Bob Fisher's case was he had an untreated mental ilnesses and live in a very high pressure enviroment that led him to crack like that.
It's not a waste of time if you are felling good with yourself and putting your mind to work. It's a pretty good and healthy way to exercise your mind.

Fishing is also a waste of time (unless you eat the fish), so maybe you should try eating the chess board.

The original quote here said, "the evidence speaks for itself." The evidence offered is that some I.G.M. went loony or deviant, worldwide humanity is deviant and look at our President to verify the omnipresence of loony. Chess isn't the problem, it is a game of mental skill, it is fighting with ideas. It is debate with concepts of moving pieces.

i couldve gone to college or stayed in my successful job, but the life of chess chose me. im the chosen one

Thanks. I will.

Anyone who thinks chess is a waste of time and intelligence has just proved their lack of intelligence.
"Chess, like wine, women, and song, has the power to make men happy"

The reality is that mastery of the game of chess makes you no more of a mental giant than the mastery of any other game.
Chess is a game of calculations and mathematics; a sport which requires the use of a very specific portion of the brain. The same can also be said for billiards,..The evidence, I’m afraid, speaks for itself.
What "evidence"? You present none whatsoever. You don't present any evidence that you have any expertise in Intelligence at Level 4 and 5 levels - analysis of data, abstraction, and self-evaluation, or any expertise in Cognition and Learning,
There is no doubt that exercises where you have to concentrate, visualize, and estimate or calculate outcomes have a positive effect on thinking efficiency and do make you "smarter."
Additionally, you present a narrow window into the mental aspects of chess. You do not mention things not measured by IQ tests like the ability to visualize, see patterns, etc. Are you at all aware how the senses are related to learning and thinking and how some people are better at some aspects than others?
There are a lot of cases, including my own, where those in their 60's or older are able to increase short-term memory by regularly playing chess.
Consequently, I ask you: why make a presentation of this before doing any research or real thinking?

Chess may be a waste of time and intelligence, considering the considerable faculties of rational analysis, stamina, clear thinking, and memory that it involves. This is true because Chess is essentially "fun" in that it involves competition and gratification -- often gratification of the ego. Chess is about asserting power. But the same aspects of intelligence and will that are involved in chess can be used for pursuits that better benefit the world, and therefore engage a person in a more complete way -- such as science and philosophy or any activity that actively benefits society and the world.
Chess may or may not help you grow as a person. It may help you grow because it's challenging and you can grow from being challenged. But it may not in the sense that the parameters of chess are extremely limited, which I suspect is part of its attraction. But given this fundamentally limited parameters, one could better spend mental energy and exertion learning about the nature of the Universe, probing the secrets of the life, understanding the human condition, or asking the big questions -- the question that genuinely expand and enhance the scope of life and genuinely fulfil the person and the human race as a whole.
Ultimately, chess is the ability of the human mind to mimic a computer. This is proven by the fact that computers are better at chess than human beings. Therefore, all that may be required for excellence in chess is the ability to use steady, computer-like reasoning faculties. This means the other faculties of being a human being -- emotional intelligence, spiritual depth, philosophical clarity, the ability to feel and love and relate to other beings, etc, are all marginalized to a certain extent when focusing on chess problems, which are the problems of dominance and power.
The only exception to this are with the people who are born to play chess, the prodigies, who are fulfilling something primary in their nature through the pursuit of chess. They may get lasting enjoyment and fulfillment from the challenge. But what obsessing about chess may do to a person on the level of their "soul" remains to be known. Chess is demonstrably one-sided and narrow and focusing in this way for too long may have detrimental effects on a person over the long-term.

What evidence do you have that chess wastes intelligence? Isn't it more likely that chess homes and strengthens and increases intelligence. Made a living as a mechanic for 40 years cleaning up messes of fellow mechanics who could not think two moves ahead. Dr. David Snowden removed and examined the brains of hundreds of old people searching for the causes of senile dementia. The only constant he found in those seniors with clear minds into their nineties was that they stayed sharp by keeping the brains active usually by playing games such as cards or draughts.
sure chess doesn't mean your smart but it definitely isn't connected with being dumb
