    History of chess | Facts you need to know right now

    The history of chess goes back many years, decades and even centuries! But who really invented the game we all love? What was the origin of this famous mental exercise many millions of people play?Chess is known the world over, played by numerous fans, but its roots and origins are not clear and are highly debatable. There are a variety of legends, stories, and plain guesses, starting from a dispute over where it came from and ending with when chess began.

    The origin of chess remains a matter of controversy. There is no credible evidence that chess existed in a form approaching the modern game before the 6th century CE. Game pieces found in RussiaChinaIndiaCentral AsiaPakistan, and elsewhere that have been determined to be older than that are now regarded as coming from earlier distantly related board games, often involving dice and sometimes using playing boards of 100 or more squares.

    One of those earlier games was a war game called chaturanga, a Sanskrit name for a battle formation mentioned in the Indian epic Mahabharata. Chaturanga was flourishing in northwestern India by the 7th century and is regarded as the earliest precursor of modern chess because it had two key features found in all later chess variants—different pieces had different powers (unlike checkers and go), and victory was based on one piece, the king of modern chess.

    How chaturanga evolved is unclear. Some historians say chaturanga, perhaps played with dice on a 64-square board, gradually transformed into shatranj (or chatrang), a two-player game popular in northern India, Pakistan, Afghanistan, and southern parts of Central Asia after 600 CE. Shatranj resembled chaturanga but added a new piece, a firzān (counselor), which had nothing to do with any troop formation. A game of shatranj could be won either by eliminating all an opponent’s pieces (baring the king) or by ensuring the capture of the king. The initial positions of the pawns and knights have not changed, but there were considerable regional and temporal variations for the other pieces .

    The game spread to the east, north, and west, taking on sharply different characteristics. In the East, carried by Buddhist pilgrims, Silk Road traders, and others, it was transformed into a game with inscribed disks that were often placed on the intersection of the lines of the board rather than within the squares. About 750 CE chess reached China, and by the 11th century it had come to Japan and Korea. Chinese chess, the most popular version of the Eastern game, has 9 files and 10 ranks as well as a boundary—the river, between the 5th and 6th ranks—that limits access to the enemy camp and makes the game slower than its Western cousin.

    Standardization of rules

    The modern rules and appearance of pieces evolved slowly, with widespread regional variation. By 1300, for example, the pawn had acquired the ability to move two squares on its first turn, rather than only one at a time as it did in shatranj. But this rule did not win general acceptance throughout Europe for more than 300 years.

    Chess made its greatest progress after two crucial rule changes that became popular after 1475. Until then the counselor was limited to moving one square diagonally at a time. And, because a pawn that reached the eighth rank could become only a counselor, pawn promotion was a relatively minor factor in the course of a game. But under the new rules the counselor underwent a sex change and gained vastly increased mobility to become the most powerful piece on the board—the modern queen. This and the increased value of pawn promotion added a dynamic new element to chess. Also, the chaturanga piece called the elephant, which had been limited to a two-square diagonal jump in shatranj, became the bishop, more than doubling its range.

    Until these changes occurred, checkmate was relatively rare, and more often a game was decided by baring the king. With the new queen and bishop powers, the trench warfare of medieval chess was replaced by a game in which checkmate could be delivered in as few as two moves.

    The last two major changes in the rules—castling and the en passant capture—took longer to win acceptance. Both rules were known in the 15th century but had limited usage until the 18th century. Minor variations in other rules continued until the late 19th century; for example, it was not acceptable in many parts of Europe as late as the mid-19th century to promote a pawn to a queen if a player still had the original queen.

    The 5 Best Benefits of Playing Chess

    Chess develops the ability to see from someone else’s perspective

    Skilled chess players learn to anticipate an opponent’s next moves. To predict what another person will do next, a player must develop the ability to adopt another person’s perspective and infer what action they are likely to take.

    Behavioral scientists call this this ability to see from another viewpoint the “theory of mind.” It’s an ability that is essential to exercising empathy and building healthy social relationships.

    Chess improves memory

    It might not be surprising to learn that expert chess players have strong memory skills. After all, the game involves memorizing numerous combinations of moves and their potential outcomes.

    It’s also interesting to note that experienced chess players show higher performance related to a particular kind of recollection: auditory memory. This is the ability to remember what you’ve learned through hearing.

    In one experiment, researchersTrusted Source compared the recall ability of expert chess players to that of people with no chess-playing experience. They found that the chess players were significantly better at recalling lists of words they’d heard than people who had never played chess.

    Skilled chess players also have a better than average ability to remember and quickly recognize visual patterns, which researchersTrusted Source think comes from memorizing complex chess positions.

    Chess enables you to enter a flow state

    Flow is a deeply rewarding sense of total involvement, in which you’re operating at a peak performance level in a challenging task. Athletes, artists, and performers often describe entering a kind of time warp, where they are so wholly focused on the task at hand that their awareness of anything beyond the performance seems to disappear.

    ResearchersTrusted Source who study brain activity noted that theta waves are heightened in electroencephalograms (EEGs) taken when people are in a state of flow. Studies have shown the same high levels of theta waves in brain scans of experienced chess players during increasingly difficult chess matches.

    Chess elevates your creativity

    Researchers at a school in India tested the creative thinking skills of two groups of students. One group was trained in chess playing, and the other was not.

    The tests asked students to come up with alternate uses for common items and to interpret patterns and meaning in abstract forms. Students who played chess scored higher on tests. Researchers concluded that chess increased the students’ ability to exercise divergent and creative thinking.

    Chess can make therapy more effective

    Some counselors and therapists play chess with clients as a means of increasing self-awareness and building more effective therapeutic relationships.

    Considered a creative therapy strategy, chess allows you to see your reactions to stress and to challenges as they arise in the course of a match. Your therapist is present to help you evaluate your responses and learn more about why you respond to problems the way you do.

  • Nikola Tesla

    Nikola Tesla

    Serbian-American engineer and physicist Nikola Tesla (1856-1943) made dozens of breakthroughs in the production, transmission and application of electric power. He invented the first alternating current (AC) motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success—unlike his early employer and chief rival, Thomas Edison.

    Nikola Tesla and Thomas Edison

    Tesla arrived in New York in 1884 and was hired as an engineer at Thomas Edison’s Manhattan headquarters. He worked there for a year, impressing Edison with his diligence and ingenuity. At one point Edison told Tesla he would pay $50,000 for an improved design for his DC dynamos. After months of experimentation, Tesla presented a solution and asked for the money. Edison demurred, saying, “Tesla, you don’t understand our American humor.” Tesla quit soon after.

    Nikola Tesla and Westinghouse

    After an unsuccessful attempt to start his own Tesla Electric Light Company and a stint digging ditches for $2 a day, Tesla found backers to support his research into alternating current. In 1887 and 1888 he was granted more than 30 patents for his inventions and invited to address the American Institute of Electrical Engineers on his work. His lecture caught the attention of George Westinghouse, the inventor who had launched the first AC power system near Boston and was Edison’s major competitor in the “Battle of the Currents.”

    Westinghouse hired Tesla, licensed the patents for his AC motor and gave him his own lab. In 1890 Edison arranged for a convicted New York murderer to be put to death in an AC-powered electric chair—a stunt designed to show how dangerous the Westinghouse standard could be.Buoyed by Westinghouse’s royalties, Tesla struck out on his own again. But Westinghouse was soon forced by his backers to renegotiate their contract, with Tesla relinquishing his royalty rights.In the 1890s Tesla invented electric oscillators, meters, improved lights and the high-voltage transformer known as the Tesla coil. He also experimented with X-rays, gave short-range demonstrations of radio communication two years before Guglielmo Marconi and piloted a radio-controlled boat around a pool in Madison Square Garden. Together, Tesla and Westinghouse lit the 1891 World’s Columbian Exposition in Chicago and partnered with General Electric to install AC generators at Niagara Falls, creating the first modern power station.

    Inventions by Nikola Tesla That Were Never Built

    1.Wireless Energy Transmission

    As someone almost completely associated with electricity, it shouldn’t be surprising that many of Tesla’s patents are in the field of electricity generation and transmission. What a lot of people don’t know is that Tesla also tried to build a tower that would transmit electricity through the air. He even got American financier J.P. Morgan to finance the building of Wardenclyffe Tower on the North Shore of Long Island, which Tesla hoped to adapt to transmit electricity to New York City.

    2.Remote Controlled Navies

    While Tesla is best known for his work with electricity, this isn’t the only area in which he worked. Another major area of work for Tesla was military technology. Like Alfred Nobel, Tesla believed that the best way to prevent war was to make it either utterly pointless or so catastrophic for the participants that no one would be mad enough to go to war again.

    With this in mind, Tesla invented a small boat that he could start, stop, and steer with radio signals. He hoped that by removing humans from the equation, “battle ships [sic] will cease to be built and the most tremendous artillery afloat will be of no more use than so much scrap iron.”

    Nikola Tesla’s Failures, Death and Legacy

    In 1895 Tesla’s New York lab burned, destroying years’ worth of notes and equipment. Tesla relocated to Colorado Springs for two years, returning to New York in 1900. He secured backing from financier J.P. Morgan and began building a global communications network centered on a giant tower at Wardenclyffe, on Long Island. But funds ran out and Morgan balked at Tesla’s grandiose schemes.Tesla lived his last decades in a New York hotel, working on new inventions even as his energy and mental health faded. His obsession with the number three and fastidious washing were dismissed as the eccentricities of genius. He spent his final years feeding—and, he claimed, communicating with—the city’s pigeons.Tesla died in his room on January 7, 1943. Later that year the U.S. Supreme Court voided four of Marconi’s key patents, belatedly acknowledging Tesla’s innovations in radio. The AC system he championed and improved remains the global standard for power transmission.

    Living Strategically: 30 Lessons Chess Teaches You About Life

    When playing chess, your brain will be challenged to exercise logic, develop pattern recognition, make decisions both visually and analytically, and test your memory. Chess can be enjoyed by any age—as a result, these brain exercises can be part of the health of your brain for your entire life!

    1.Everyone’s playing. Sometimes it’s a friendly, often it is more serious. The problem is that not everyone knows they’re playing – even after they have made a move.

    2.Ignore what your opponent is trying to do at your own peril. We often get so absorbed in our own games and machinations that we ignore what is going on around us. Be aware of threats and alert to opportunities.

    3.In chess, every move has a purpose. Life obviously cannot be lived with this much unceasing calculation, nor should we want to live it that way, but there are times when we must align our actions with a predetermined strategy, instead of bumbling through it.

    4.Play for the advantage. If you already have it, maintain it. If you don’t have it, seize it.

    5.Seize the initiative. If you wait around for someone else to make a decision for you, they will… and you probably won’t like how it turns out.

    6.Learn to spot patterns. There are often clearly defined lines of success that work well. Learn to see these when they repeat, and take advantage of them.

    7.If you only play patzers, you never really improve – take on a few tough challenges, and even if you lose, try to learn something new.

    8.Cut your losses. Sometimes you are going to lose material. Try to minimize your losses and move on.

    9.Sometimes you get stuck in a position known in chess as zugzwang: where whichever move you make is a bad one. This is just the way it goes sometimes, in chess and in life.

    10.There is nothing more satisfying than a discovered attack: Pretending to do one thing while attacking somewhere else. Learn to play and live less obviously and on more levels. This makes you less predictable and more interesting.

    11.If you spend all of your time chasing lowly pawns, you may be on the receiving end of an opponent who cares less about small victories and more about winning the war.

    12.Don’t get pinned down. Where something more cherished cannot be brought into play because it is stuck behind something trivial, make every effort to get it into the game – as soon as possible.

    13.Play for the middle. Don’t hold back too much, and don’t push through too early. Your opportunity will come.

    14.Accumulate small advantages

    15. Don’t be overly impressed with lofty words or titles. The only thing worse than being overly diffident towards those who outrank you is being dismissive of those inferior to you.

    16.Surprise and impress people with unconventional moves. But not with dumb ones. Creativity always has a purpose – doing something wild and crazy just for the sake of it may be fun at the time, but ultimately has no value. Break the rules – but only if it serves a good purpose.

    17.Don’t get swept up by distractions

    18.Always consider the whole board when deciding on a move: decisions made with too narrow a focus are often bad.

    19. Enjoy yourself

    20.Deep and meaningful is always better than superficially pretty.

    21.Connect your pieces cleverly. Collaboration and cooperation are the keys to success

    22. Sometimes a draw is as good as a win. But a draw is always better than a loss.

    23. If you lose, do so graciously and try to learn at least one important lesson.

    24.Keep calm and move slowly.

    25. If you are feeling boxed-in, free things up.

    26.In the endgame, attack the King by focussing your attention on his escape squares: When you are in the final stretch, and about to win, anticipate what could go wrong and plan accordingly.

    27.Have a Plan B. And a Plan C. If none of those work, you’re probably doomed.

    28.When someone makes a move that you cannot understand, don’t read more into it than you need to. Sometimes people just make silly moves – that’s all there is to it.

    29. A threat is best met with a move that improves your own position. Don’t get trapped into mindlessly trading moves and material in anger. Sometimes the solution is more gentle and cerebral.

    30.Be prepared to sacrifice material for position. Sometimes even the greatest material sacrifice can result in a winning position later on.
