Who Is the Lowest IQ Chess Grandmaster?

When it comes to chess, it’s easy to assume that intelligence can be a game-changer. After all, the game demands strategic thinking, problem-solving, and pattern recognition, which are all related to one’s intelligence.

On top of that, most grandmasters in the game’s history have high IQs, such as Magnus Carlsen, Gary Kasparov, and Bobby Fischer.

Despite the significance of IQ in chess, some players managed to become grandmasters, even though their IQs were low. This begs the question, who’s the lowest IQ chess grandmaster?

It’s hard to answer this question since information about chess grandmasters’ IQ isn’t publicly available. However, many players managed to become grandmasters even though they didn’t have exceptionally high IQs.

In this article, we’ll discover how important one’s IQ is in chess. We’ll also discover how lower IQ players became grandmasters.

The Significance of IQ in Chess

IQ, or Intelligence Quotient, measures one’s cognitive abilities relative to a population.

The score is derived from standardized tests designed to measure different aspects of intelligence. That includes problem-solving, logical thinking, fluid thinking, and short-term memory.

The majority of people have an average IQ of 85 to 115. In addition, 98% of people have an IQ score that’s below 130.

Many people wonder if there’s a strong connection between chess and IQ. That’s true, but only up to a point.

Chess skills and intelligence go hand-in-hand. However, factors such as talent, hard work, and dedication also affect how far you can go in chess.

Chess utilizes six out of seven factors of the modern IQ tests:

  1. Working Memory
  2. Visual-spatial processing
  3. Quantitative reasoning
  4. Fluid reasoning
  5. Non-verbal IQ
  6. Knowledge

This shows how much IQ and chess are connected. In addition, many studies have shown that intelligence plays a huge role in determining someone’s chess skills.

That said, most chess grandmasters have an IQ score higher than 100. Some of the greatest chess players of all time have astonishing numbers, such as:

  • Magnus Carlsen: 190
  • Bobby Fischer: 181
  • Mikhail Tal: 175
  • Sergey Karjakin: 160

Looking at these numbers, it’s clear that being a chess grandmaster demands a high IQ score. However, many players became grandmasters even though they had lower IQ scores.

Lowest IQ Chess Grandmasters

IQ scores aren’t publicly available for all chess grandmasters, and not all players have taken the IQ test. So, we can’t say which chess grandmaster has the lowest IQ score.

However, we’ve made a list of five chess grandmasters with low IQs.

Nigel Short

Nigel Short is one of history’s best and most famous British chess grandmasters. He became a grandmaster at the age of 19. He’s most famous for his qualification to challenge Garry Kasparov for the world championship in 1993.

The British grandmaster was among the highest-rated European players in 2010, achieving a career rating of 2860. However, despite his remarkable accomplishments and skills, Nigel Short has an IQ of 110, which is quite low compared to other chess grandmasters.

Peter Leko

Peter Leko is a Hungarian chess grandmaster who gained prominence in chess at a young age. He became a grandmaster at 14 in 1994, becoming the youngest grandmaster at that time.

The Hungarian chess prodigy ranked fourth in the FIDE world rankings in 2003. However, Leko has an IQ of 125.

Hikaru Nakamura

Hikaru Nakamura is an American chess grandmaster. He’s widely considered one of the top chess players in the United States.

Nakamura became a grandmaster at the age of 15, and since then, he represented the USA in multiple tournaments, including five Chess Olympiads. In addition, he secured a team gold medal and two team bronze medals.

Nakamura is notorious for being a dominant force in rapid and blitz chess. He also has a huge online presence on streaming platforms such as YouTube and Twitch, where he shares his knowledge and expertise with his wide audience.

Despite reaching a peak Elo rating of 2816, Nakamura once said he scored only 102 in an IQ test he took in the past. That’s a bit low compared to his chess skills and achievements.

Vladimir Kramnik

Vladimir Kramnik is a Russian chess grandmaster who’s arguably among the top ten chess players of all time. He held the World Chess Champion title from 2000 to 2006.

Kramnik defeated reigning World Champion Garry Kasparov in 2000, becoming the Classical World Chess Champion. Years later, Kramnik defended his title against Peter Leko in 2004. He did the same 2 years later by defeating Veselin Topalov.

As a result, Vladimir Kramnik became the first undisputed World Champion as he held both the Classical and FIDE titles.

Wijk aan Zee, Tal Memorial, Linares, and M-Tel Masters. Following the footsteps of Bobby Fischer, Ivanchuck has beaten every FIDE and Classical World Champion, from Anatoly Karpov to Magnus Carlsen.

Vasyl is notorious for his exceptional, unpredictable, and creative playstyle. He’s a well-rounded player who does everything extremely well, from opening preparation to unexpected sacrifices and imaginative play.

Despite that, Vasyl Ivanchuk reportedly has an IQ of only 119, which isn’t that high compared to his performance and accomplishments.

Final Words

So, who’s the lowest IQ chess grandmaster? Unfortunately, it’s hard to tell since IQ scores for most grandmasters aren’t available to the public.

However, some outstanding chess grandmasters, such as Nigel Short, Vasyl Ivanchuk, Vladimir Kramnik, Peter Leko, and Hikaru Nakamura, reportedly have quite low IQs.

On the other hand, most chess grandmasters have impressive IQ scores, such as Magnus Carlsen, Bobby Fischer, Mikhail Tal, and Sergey Karjakin.

While intelligence is crucial to becoming a chess grandmaster, it isn’t the only factor. Chess also demands patience, focus, training, and time management.
