Many of my students have requested guidance on the subject of computer chess programs. In my where I interviewed over 40 leading chess grandmasters, the expert answer almost always recommended to stay away from using a computer chess program for analysis until reaching a very advanced level (usually around 2200-2400). It is important to point out that using a computer chess program for tactical and endgame exercises is a very efficient method of study, and also that using a computer chess program to double-check your analysis is perfectly acceptable. The moral of the story – computer chess programs aren’t all bad, but are better for your chess game in small doses.

For more information on computer chess programs, the below list features three of the best computer chess programs currently on the market. Click the following link for information on Shredder. Shredder is a computer chess program that has remained at the top of the international scene for almost 2 decades. Shredder has won many WorldComputer Chess Champion Titles in blitz and standard chess, and has proven without a doubt that it is one of the stronges computer chess programs conceived to date. The latest PC/Mac version is Shredder 12 and is priced at just under $70 USD. One of the things that I like about Shredder is that the software is more user-friendly and a bit easier to learn than some of the other top computer chess programs. Shredder offers a 30-day Free download trial for potential customers to check out the hardware and make sure it’s a good match.

Shredder is also very well-known for it’s iPhone and iPad apps that sell for less than $10 each and enable the user to study chess in any situation. For any readers that maintain websites, Shredder provides a free plug-in with daily updated easy, medium, and difficult chess puzzles. Although I believe chess players should avoid chess engines until they reach a more advanced level, I would recommend Shredder for chess players of all levels who are interested in working with a computer chess programs. Rybka has remained the undisputed strongest computer chess program in the world since 2007 – however just how it got to the top is currently being disputed. From 2007-2010, Rybka won 4 straight World Computer Chess Championships. In 2010, Deep Rybka 3 was rated over 200 points higher than the nearest opposition.

However, in June 2011 founder IM Vasik Rajlich was officially accused by the International Computer Games Association to have plagiarized programming code from top open-source rivals Crafty and Fruit. The case is still pending, although. As for the quality of the product, Rybka is the strongest chess engine in the world today. The latest version – Rybka 4 UCI – is priced at just under $50 USD and is definitely one of the most powerful personal computer chess programs ever created. Potential users can also download an earlier and more basic version of Rybka 2.3.2a to get a feel for the computer chess software and see if they like it. Rybka is a computer chess program that has been created with the advanced chess player in mind, and I would not recommend it for beginner to intermediate chess players. Fritz 13 is definitely one of the best computer chess programs on the market, because it is much more accessible to the average player.

Fritz 13 is not as strong as the aforementioned computer chess programs, however Fritz 13 offers a variety of training programs focused on opening mastery, tactical awareness, and endgame technique. Fritz 13 is also a very personalized computer chess program includes insight and commentary by many leading Grandmasters (, etc.). If you are especially confounded by a position, a cool feature of Fritz 13 enables the user to send this position to a central server where it can be analyzed by other users and engines to provide a fail-safe answer to any chess question. Fritz 13 costs $50 USD and is highly recommended for chess players of all levels due to the interactive features of the software.

This article documents the progress of significant human–computer chess matches. Were first able to beat strong players in the late 1980s. Their most famous success was the victory of over then in 1997, but there was some controversy over whether the match conditions favored the computer.

In 2002–2003 three human-computer matches were drawn. But whereas Deep Blue was a specialized machine, these were chess programs running on commercially available computers. Chess programs running on commercially-available desktop computers had convincing victories against human players in matches in 2005 and 2006.

Since that time, chess programs running on commercial hardware - more recently including mobile phones - have been able to defeat even the strongest human players. Contents. MANIAC (1956) In 1956, developed at, became the first computer to defeat a human in a chess-like game. Playing with the simplified, it defeated a novice in 23 moves. Mac Hack VI (1966–1968) In 1966 student wrote the chess program VI using MIDAS macro assembly language on a computer with 16K of memory.

Mac Hack VI evaluated 10 positions per second. In 1967, several MIT students and professors (organized by ) challenged Dr.

To play a game of chess against Mac Hack VI. Dreyfus, a professor of philosophy at MIT, wrote the book What Computers Can’t Do, questioning the computer’s ability to serve as a model for the human brain. He also asserted that no computer program could defeat even a 10-year-old child at chess.

Dreyfus accepted the challenge., an pioneer, watched the game. He said “It was a wonderful game – a real cliffhanger between two woodpushers with bursts of insights and fiendish plansgreat moments of drama and disaster that go in such games.” The computer was beating Dreyfus when he found a move, which could have captured the enemy queen. The only way the computer could get out of this was to keep Dreyfus in checks with its own queen until it could fork the queen and king, and then exchange them. That is what the computer did. Soon, Dreyfus was losing. Finally, the computer checkmated Dreyfus in the middle of the board. In the spring of 1967, Mac Hack VI played in the Boston Amateur championship winning 2 games and drawing 2 games.

Mac Hack VI beat a 1510 player. This is the first time a computer won a game in a human tournament. At the end of 1968, Mac Hack VI achieved a rating of 1529. The average rating in the USCF was near 1500.

Chess x.x (1968–1978) In 1968, students Larry Atkin, David Slate and Keith Gorlen began work on. On July 25, 1976, Chess 4.5 scored 5–0 in the Class B (1600–1799) section of the 4th Paul Masson chess tournament in Saratoga, California. This was the first time a computer won a human tournament.

Chess 4.5 was rated 1722. Chess 4.5 running on a 175 (2.1 ) looked at less than 1500 positions per second. On February 20, 1977, Chess 4.5 won the 84th Minnesota Open Championship with 5 wins and 1 loss. It defeated expert Charles Fenner rated 2016. On April 30, 1978, Chess 4.6 scored 5–0 at the Twin Cities Open in Minneapolis. Chess 4.6 was rated 2040. Stated that year, 'My contention that computers cannot play like a master, I retract.

They play absolutely alarmingly. I know, because I have lost games to 4.7.' David Levy's bet (1978). Main article: For a long time in the 1970s and 1980s it remained an open question whether any Chess program would ever be able to defeat the expertise of top humans.

In 1968, International Master made a famous bet that no chess computer would be able to beat him within ten years. He won his bet in 1978 by beating (the strongest computer at the time), but acknowledged then that it would not be long before he would be surpassed.

Cray Blitz (1981) In 1981, scored 5–0 in the Mississippi State Championship. In round 4 it defeated Joe Sentef (2262) to become the first computer to beat a master in tournament play and the first computer to gain a master rating (2258).

HiTech (1988) In 1988, won the Pennsylvania State Chess Championship with a score of 4.5–0.5. HiTech defeated International Master (2485). The Harvard Cup Man versus Computer Chess Challenge was organized by Harvard University. There were six challenges from 1989 until 1995. They played in Boston and New York City. In each challenge the humans scored higher and the highest scorer was a human. Year Men-Compu.

The Dutch Computer Chess Federation (CSVN) organized the Aegon Man-Machine Tournaments in The,. The insurance company hosted the tournaments. An equal number of humans and computers played a 6 round with all games between humans and computers. The early tournaments were mostly local players and specialists.

Later tournaments included masters and grandmasters. In the early tournaments, humans won more games. In the later tournaments, computers won more games. 100 players played in the 1997 tournament. Computers won 151 ½ points.

Humans won 148 ½ points. Scored highest for the humans at 6 points out of 6 games. Kallisto scored highest for the computers at 4 ½ points.

Final position Kasparov played a six-game match against in 1996. Kasparov lost the first game , the first time a reigning world champion had lost to a computer using regular time controls. However, Kasparov regrouped to win three and two of the remaining five games of the match, for a convincing 4–2 match victory. 1997 In May 1997, an updated version of defeated Kasparov 3½–2½ in a highly publicized six-game match. Kasparov won the first, lost the second, and drew the next three. The match was even after five games but Kasparov was crushed in.

This was the first time a computer had ever defeated a world champion in match play. A was made about this famous match-up entitled. In that film Kasparov casually says, 'I have to tell you that, you know, was not just a single loss of a game.

It was a loss of the match, because I couldn't recover.' It should be noted however, that in game 6, Kasparov blundered very early into the game. Kasparov cites tiredness and unhappiness with the IBM team's conduct at the time as the main reason. Kasparov claimed that several factors weighed against him in this match.

The DropBox and a single disc. Tunebite license key generator. As a result, you can move your multimedia tracks to the network and playback on your mobile device.

In particular, he was denied access to Deep Blue's recent games, in contrast to the computer's team that could study hundreds of Kasparov's. After the loss Kasparov said that he sometimes saw deep intelligence and creativity in the machine's moves, suggesting that during the second game, human chess players, in contravention of the rules, intervened. IBM denied that it cheated, saying the only human intervention occurred between games. The rules provided for the developers to modify the program between games, an opportunity they said they used to shore up weaknesses in the computer's play revealed during the course of the match. Kasparov requested printouts of the machine's log files but IBM refused, although the company later published the logs on the Internet.

Kasparov demanded a rematch, but IBM refused and dismantled Deep Blue. Kasparov maintains that he was told the match was to be a scientific project but that it soon became apparent that IBM wanted to beat him and nothing more. Anand – REBEL (1998) With increasing processing power, Chess programs running on regular workstations began to rival top flight players. In 1998, defeated who at the time was ranked second in the world, by a score of 5–3.

However most of those games were not played at normal time controls. Out of the eight games, four were games (five minutes plus five seconds Fischer delay (see ) for each move) these Rebel won 3–1. Then two were semi-blitz games (fifteen minutes for each side) which Rebel won as well (1½–½). Finally two games were played as regular tournament games (forty moves in two hours, one hour sudden death) here it was Anand who won ½–1½. At least in fast games computers played better than humans but at classical time controls — at which a player's rating is determined — the advantage was not so clear.

Deep Junior at Dortmund (2000) played 9 grandmasters at the Sparkassen Chess Meeting in Dortmund, Germany from July 6 to July 17, 2000. The 2000 Sparkassen Chess Meeting was a category 19 chess tournament. Computer program Deep Junior competed in a round robin format. Deep Junior scored 4.5 in 9 rounds.

Deep Junior performed at a rating of 2703. Round White Elo Black Elo Result Moves ECO 1 Bareev, E 2702 Deep Junior ½–½ 146 D46 2 Deep Junior Huebner, R 2615 1-0 39 C04 3 Adams, M 2755 Deep Junior ½–½ 84 C68 4 Deep Junior Khalifman, A 2667 ½–½ 129 B08 5 Kramnik, V 2770 Deep Junior 1-0 65 D00 6 Deep Junior Akopian, V 2660 ½–½ 89 B00 7 Anand, V 2762 Deep Junior ½–½ 35 D05 8 Deep Junior Piket, J 2649 0-1 68 B15 9 Leko, P 2740 Deep Junior 0-1 120 C48 Kramnik – Deep Fritz (2002) In October 2002, (who had succeeded Kasparov as Classical ) and competed in the eight-game match, which ended in a 4–4 draw. Kramnik was given several advantages in his match against Fritz when compared to most other Man vs. Machine matches, such as the one Kasparov lost against Deep Blue in 1997. The code of Fritz was frozen some time before the first match and Kramnik was given a copy of Fritz to practice with for several months.

Another difference was that in games lasting more than 56 moves, Kramnik was allowed to adjourn until the following day, during which time he could use his copy of Fritz to aid him in his overnight analysis of the position. Kramnik won games 2 and 3 by 'conventional' — play conservatively for a long-term advantage the computer is not able to see in its game tree search. Fritz, however, won game 5 after a severe blunder by Kramnik. Game 6 was described by the tournament commentators as 'spectacular.' Kramnik, in a better position in the early, tried a piece sacrifice to achieve a strong tactical attack, a strategy known to be highly risky against computers who are at their strongest defending against such attacks. True to form, Fritz found a watertight defense and Kramnik's attack petered out leaving him in a bad position.

Kramnik resigned the game, believing the position lost. However, post-game human and computer analysis has shown that the Fritz program was unlikely to have been able to force a win and Kramnik effectively sacrificed a drawn position.

The final two games were draws. Given the circumstances, most commentators still rate Kramnik the stronger player in the match. Kasparov – Deep Junior (2003) In January 2003, Kasparov engaged in a six-game classical time control match with a $1 million prize fund which was billed as the FIDE 'Man vs. Machine' World Championship, against. The engine evaluated three million positions per second. After one win each and three draws, it was all up to the final game. The final game of the match was televised on ESPN2 and was watched by an estimated 200–300 million people.

After reaching a decent position Kasparov offered a draw, which was soon accepted by the Deep Junior team. Asked why he offered the draw, Kasparov said he feared making a blunder. Originally planned as an annual event, the match was not repeated. Kasparov – X3D Fritz (2003) In November 2003, Kasparov engaged in a four-game match against the computer program (which was said to have an estimated rating of 2807)using a virtual board, and a system. After two draws and one win apiece, the X3D Man-Machine match ended in a draw.

Kasparov received $175,000 for the result and took home the golden trophy. Kasparov continued to criticize the blunder in the second game that cost him a crucial point. He felt that he had outplayed the machine overall and played well. 'I only made one mistake but unfortunately that one mistake lost the game.'

Man vs Machine World Team Championship (2004–2005) The Man vs Machine World Team Championships were two tournaments in, between leading chess grandmasters and chess computers. Both were convincingly won by the computers. A second name for the tournaments is Human vs.

Computers World Team Matches. 2004 In October 2004, (then having Elo 2710), (Elo 2757) and (Elo 2576) played against computers, 8, and. Ponomariov and Topalov were world chess champions. Sergey Karjakin at 12 was the youngest.

Hydra was running on a special machine with 16 processors located in Abu Dhabi, UAE; Deep Junior, the then reigning computer chess world champion, used a remote 4 x 2.8 GHz Xeon machine located at Intel UK (Swindon); and Fritz 8 was running on a Centrino 1.7 GHz notebook. The computers won 8.5 to 3.5.

The humans won one game: Karjakin, the youngest and lowest rated player, defeated Deep Junior. Ponomariov – Hydra 0–1. Fritz – Karjakin 1–0. Deep Junior – Topalov 1/2–1/2. Karjakin – Deep Junior 1–0.

Ponomariov – Fritz 1/2–1/2. Topalov – Hydra 1/2–1/2. Deep Junior – Ponomariov 1/2–1/2.

Hydra – Karjakin 1–0. Fritz – Topalov 1–0. Hydra – Ponomariov 1–0. Karjakin – Fritz 0–1. Topalov – Deep Junior 1/2–1/2 2005 In November 2005, 3 former world chess champions, and played against computers Hydra, Junior and Fritz.

The computers won 8 to 4. The Ponomariov vs Fritz game on November 21, 2005 is the last known win by a human against a top performing computer under normal chess tournament conditions. Ponomariov – Junior 0–1. Hydra – Kasimdzhanov 1–0. Fritz – Khalifman 1–0. Ponomariov – Fritz 1–0.

Kasimdzhanov – Junior 1/2–1/2. Khalifman – Hydra 1/2–1/2. Hydra – Ponomariov 1–0.

Fritz – Kasimdzhanov 1/2–1/2. Junior – Khalifman 1–0. Ponomariov – Junior 1/2–1/2.

Kasimdzhanov – Hydra 1/2–1/2. Khalifman – Fritz 1/2–1/2 Hydra – Adams (2005) In 2005, a dedicated chess computer with custom hardware and sixty-four processors and also winner of the 14th IPCCC in 2005, crushed seventh-ranked 5½–½ in a six-game match.

While Adams was criticized for not preparing as well as Kasparov and Kramnik had, some commentators saw this as heralding the end of human-computer matches. Kramnik – Deep Fritz (2006) Kramnik, then still the World Champion, played a six-game match against the computer program in, from November 25 to December 5, 2006, losing 4–2 to the machine, with two losses and four draws. He received 500,000 for playing and would have received another 500,000 Euros had he won the match. Deep Fritz version 10 ran on a computer containing two Intel (a Xeon DC 5160 3 GHz processor with a 1333 MHz FSB and a 4 MB L2 cache) and was able to evaluate eight million positions per second. Kramnik received a copy of the program in mid-October for testing, but the final version included an updated.

Except for limited updates to the opening book, the program was not allowed to be changed during the course of the match. The used by the program were restricted to five pieces even though a complete six-piece tablebase is widely available. While Deep Fritz was in its opening book Kramnik is allowed to see Fritz’s display.

The Fritz display contains opening book moves, number of games, Elo performance, score from grandmaster games and the move weighting. In the first five games Kramnik steered the game into a typical 'anti-computer' positional contest. On November 25, the first game ended in a draw at the 47th move. A number of commentators believe Kramnik missed a win.

Two days later, the second game resulted in a victory for Deep Fritz, when Kramnik made what might be called the 'blunder of the century' according to, when he failed to defend against a threatened mate-in-one in an even position. ( see also ). The third, fourth and fifth games in the match ended in draws. In the final game, in an attempt to draw the match, Kramnik played the more aggressive and was crushed, losing the match 4–2. There was speculation that interest in human-computer chess competition would plummet as a result of the 2006 Kramnik–Deep Fritz match.

According to McGill University computer science professor Monty Newborn, for example, 'the science is done'. The prediction appears to have come true, with no major human-computer matches in the next 10 years.

Rybka odds matches (2007–2008) Since 2007 has played some against grandmasters. First lost a pawn-odds match, then later lost a match when given time, color, opening, and endgame advantages. Then lost a match when given pawn and move odds. In September 2008, Rybka played an odds match against, its strongest opponent yet in an odds match. (Milov at the time had an of 2705, 28th in the world). The result was a narrow victory to Milov: He had won 1½–½ when given pawn-and-move, and 2½–1½ (1 win, 3 draws) when given exchange odds but playing black. In two standard games (Milov had white, no odds), Rybka won 1½–½.

Pocket Fritz 4 (2009) In 2009 a chess engine running on slower hardware, a 528 MHz HTC Touch HD, reached the level. The mobile phone won a 6 tournament with a performance rating 2898.

The chess engine 13 runs inside 4 on the mobile phone. Pocket Fritz 4 won the Copa Mercosur tournament in with 9 wins and 1 draw on August 4–14, 2009. Pocket Fritz 4 searches fewer than 20,000 positions per second.

This is in contrast to supercomputers such as Deep Blue that searched 200 million positions per second. Pocket Fritz 4 achieves a higher performance level than Deep Blue. Pocket Fritz 3 using version 12.1 of Hiarcs won the same event the previous year with six wins and four draws, running on a 624 MHz HP iPAQ hx2790. The 2008 Mercosur Cup was a category 7 tournament. Pocket Fritz 3 achieved a performance rating of 2690.

Komodo handicap matches (2015) In 2015, chess engine played a series of matches with GM Sergej Movsesian, GM Martin Petr, GM Petr Neuman, FM Victor Bolzoni, FM John Meyer, Mark Gray and FM Larry Gilden. These games included one pawn, two pawn, exchange (rook for knight), and knight odds.

Komodo fared well in all of these games, drawing a majority but winning at least one in all configurations. References.
