Fast chess (also known as speed chess) is a variation of chess in which each side is given less time to make a move than under normal tournament time controls. This means that each player will have less than 60 minutes at his or her disposal, based on a 60-move game, and sometimes considerably less than this. Fast chess can be further subdivided, by decreasing time controls, into rapid chess, blitz chess, and bullet chess. Armageddon chess is a particular variation in which different rules apply for each of the two players.

The 2016 World Rapid Chess Champion is Vassily Ivanchuk from Ukraine, and the 2016 World Blitz Chess Champion is Sergey Karjakin. Anna Muzychuk, also from Ukraine, won both the 2016 Women world Rapid and Blitz Championships.

Background

FIDE divide time controls for chess into "classical" time controls, and the fast chess time controls. Currently, for master-level players (with an Elo of 2200 or higher) the regulations state that at least 120 minutes per player (based on a 60-move game) must be allocated for a game to be rated on the "classical" list.[1] Games played faster than this may be rated under the time controls of rapid and blitz, but only if they comply with the time controls for those categories.[2]

More recently in November 2015, Oleg Skvortsov and Christian Issler on behalf of the Zurich Chess Club have petitioned FIDE to allow the rating of 40 minute games as classical chess (instead of the current Rapid classification),[3] but there was no response.[4]

Overview

A fast chess game can be further divided into several categories, which are primarily distinguished by the selection of time controls. Games may be played with or without time increments per move.

Rapid, rapid play or quick

Time controls for each player in a game of rapid chess are, according to FIDE, more than 10 minutes, but less than 60 minutes.[2] Rapid chess can be played with or without time increments for each move. In a game where time increments are used, a player can automatically gain, for instance, ten more seconds on the clock after each move. In a case where time increments are used, the total time per player for a 60 move game must be more than 10 minutes, but less than 60 minutes.[2]

For the FIDE World Rapid Championship, each player will have 15 minutes, plus 10 seconds additional time per move starting from move 1.[5]

The USCF quick chess rating for players is based on games with time controls per player greater than 10 minutes, up to a maximum of 65 minutes.[6] Games between 30 and 65 minutes per player are dual rated for both quick and regular ratings.[6]

From 1987 to 1989 FIDE referred to rapid chess as active chess.[7]

Blitz

Time controls for each player in a game of blitz chess are, according to FIDE, 10 minutes or less per player.[2] Can be "sudden death", with no time increment per move; but may also be played with a small increment per move, a more recent development due to the influx of digital clocks. Three minutes with a two-second increment is preferred. In the case of time increments, the total time per player for a 60 move game must be 10 minutes or less (hence averaging 10 seconds or less per move: see "lightning" below).[2]

For the FIDE World Blitz Championship, each player has 3 minutes, plus 2 seconds additional time per move starting from move 1.[5]

The USCF define blitz chess as time controls between 5 and 10 minutes per player.[6]

The terms blitz or blitzkrieg in chess sometimes means a quick attack on the f7 or f2 square early in the game, putting the king in check.[8] This term is not limited to fast chess.

Bullet

A variant of blitz chess, bullet chess games have less than three minutes per player, based on a 40 move game;[9][10] although one minute per player chess can be excluded.[11] Common time controls for this setting is 2 minutes with one-second increment or 1 minute with a two-second increment. The term lightning can also be applied to this variant.

Bullet chess is an especially popular format in online chess for various reasons. For one, the speed of bullet chess makes it harder for opponents to cheat using chess engines. In addition, online bullet chess lacks the typical practical issues normally associated with live bullet chess, particularly players accidentally knocking over the pieces.

Under USCF rules bullet games are not rateable, referring to any time control below five minutes.[6]

Lightning

A general term for extremely fast chess. It can also refer to games with a fixed time (e.g. ten seconds) for each move. This also can be used for one-minute games.

Armageddon

A game guaranteed to produce a decisive result, because Black has draw odds (that is, for Black, a draw is equal to a victory). To compensate, White has more time on the clock. Common times are six minutes for White and five for Black, or five minutes for White and four for Black. This can also be played with a small increment.[12] This is also known as "time odds" and it is used in various tie breaks for quick tournaments. An example of Armageddon was played by Ian Nepomniachtchi vs Hikaru Nakamura at the 2015 FIDE World Cup.[13]

History and rules

Before the advent of digital clocks, five minutes per side was the standard for blitz or speed chess. Before the introduction of chess clocks in the mid-1950s chess club "rapid transit" tournaments had a referee who every ten seconds called out. The Washington Divan (2445 15th St. NW) had regular weekly games and used a special clock that beeped every ten seconds to indicate the time to move. Players had to use their full ten seconds and move on the bell.

In 1988 Walter Browne formed the World Blitz Chess Association and its magazine Blitz Chess, which folded in 2003.[14]

In some chess tournaments and matches, the final standings of the contestants may be resolved by a series of games with ever shortening control times as tie breaks. In this case, two games may be played with each time control, as playing with black or white pieces is not equally liked among players. The short time controls in fast chess reduce the amount of time available to consider each move, and may result in a frantic game, especially as time runs out. A player whose time runs out automatically loses, unless the opposing player has insufficient material to checkmate, in which case the game is a draw. "Losing on time" is possible at even the longer, traditional time controls, but is more common in blitz and rapid versions.

The play will be governed by the FIDE Laws of Chess, except when they are overridden by the specific tournament. A common rule used in fast chess tournaments is that if a player makes an illegal move, the player's opponent may point it out and claim a win. For example, if a player leaves his or her king in check, the other player may claim the win. This rule can be left out for a friendly game or left in for what some consider to be a more exciting and fun game. However, in case of a dispute during a tournament, either player may stop the clock and call the arbiter to make a final and binding judgment.

Chess boxing uses a fast version for the chess component of this sport.

USCF rules for Quick and Blitz chess

The rules for fast chess differ between FIDE and the USCF.

With the USCF, a game is considered to affect the Quick rating with more than 10 minutes, but up to 65 minutes, time controls per player.[6] As 30 minute to 65 minute per player time controls are also under the Regular rating system, these games affects both the Quick and Regular ratings,[6] and are known as dual rated games. However, the K factor (a statistic used for ratings) is reduced by comparison, meaning that players will either lose or gain (or rarely both) less rating points compared to a solely Quick or Regular game. Any time control over 65 minutes counts under the Regular rating only.[6] All of these time controls include the delay added to the time control, such as a 60 minute with a 5-second delay is still considered to be a 60-minute game, not a 65-minute game.

As of March 2013, the USCF has also added a separate Blitz class rating, for any time control between 5 and 10 minutes per player.[6] It is not possible for a game to be dual rated as both Blitz and Quick. Unlike Quick chess, 5 minutes can also mean game 3+2 (three minutes with a two-second increment).

World championships

Both FIDE sponsored official, and unofficial, World championships for fast chess have been held since the seventies. The World Rapid and Blitz Championships 2016, as well as the Women's World Rapid and Blitz Championships 2016, were held in Doha, Qatar in December 2016.[15]

World Rapid championships before 2012

In 1987, Garry Kasparov (the World Champion of classical chess at the time) and Nigel Short played a 6-game exhibition Rapid match ("Speed Chess Challenge") at the London Hippodrome, won by Kasparov 4-2.[16][17]

The 1988 victory by Anatoly Karpov in Mazatlan was officially called the World Active Championship, but FIDE changed the word 'active' to 'rapid' soon after.[7]

In 1992 FIDE held the Women’s World Rapid and Blitz Championship in Budapest, Hungary. Both Rapid and Blitz Championships were won by Susan Polgar.[18]

The 2001 victory by Garry Kasparov in the FIDE World Cup of Rapid Chess (organized by the French Chess Federation in Cannes) was held contemporaneously to the Melody Amber rapids (thus splitting the top players between the two events),[19] and is sometimes considered to be official, but it was never named as a "championship" but rather a "world cup".[20]

Viswanathan Anand won the official FIDE 2003 Rapid Championship at the 6th Cap d'Agde event.[21] After no bids in 2004, FIDE optioned the 2005 Rapid to Cap d'Agde, but it was not held.[22] Teimour Radjabov won the 2006 7th Cap d’Agde Rapid Chess Tournament, but this had no FIDE status.[23]

The yearly Frankfurt or Mainz events hosted by the Chess Tigers (2001-2010) were considered as the traditional rapid chess championship,[24] sometimes being billed as a world championship.[25] In its last two years, the 2009 Grenkeleasing World Rapid Chess Championship in Mainz was won by Levon Aronian,[26] and the 2010 Open GRENKE Rapid World Championship in Mainz was won by Gata Kamsky.[27] However, these are not official titles. The Association of Chess Professionals (ACP) also held a World Rapid Cup in some of these years, and the annual Amber chess tournament (1992 to 2011) also had a rapid segment. There was also occasionally a Eurotel Trophy or Intel Grand Prix event, each of which would be of high stature.

World Blitz championships before 2012

The first unofficial Speed Chess Championship of the World (or World Blitz Championship) was held in Herceg Novi on 8 April 1970. This was shortly after the first USSR versus the rest of the world match (in Belgrade), in which ten of these players also competed. Eleven Grandmasters and one International Master played a double round-robin tournament. Bobby Fischer won first place, with a score of 19 points out of a possible 22. Fischer scored seventeen wins, four draws, and one loss (to Korchnoi). Mikhail Tal was a distant second, 4½ points behind.[28] Fischer won both games against each of Tal, Tigran Petrosian, and Vasily Smyslov; all of them being past World Champions.

By 1971 the Russian and Moscow five-minute championships had been going several years, with Tal, Bronstein and Petrosian all having success. That year Fischer played in a blitz tournament organised by the Manhattan Chess Club, who scored 21½/22.[29] There were also strong tournaments in Bugojno (in 1978), which was won by Karpov; and Nikšić (in 1983), which was won by Kasparov.[30]

The 1st World Blitz Championship was won by Mikhail Tal in 1988.[30]

In 1992 FIDE held the Women’s World Rapid and Blitz Championship in Budapest, Hungary. Both Rapid and Blitz Championships were won by Susan Polgar.[18]

In 2000 Anand won the Plus GSM World Blitz Chess Cup,[31] which has been sometimes referred to as a Championship,[32] but there is no contemporary acknowledgement of this title.

The 2nd World Blitz Championship was won by Alexander Grischuk in 2006;[30] the 3rd World Blitz Championship was won by Vassily Ivanchuk in 2007.[30] The 4th World Blitz Championship was held in Almaty in 2008, and was won by Leinier Dominguez Pérez of Cuba.[33][30]

In 2009 and 2010 there was an event called the World Blitz Championship, held after the Tal Memorial in Moscow in November. They were won by Magnus Carlsen (in 2009)[34] and Levon Aronian (in 2010),[35] with the Women's Championship being won by Kateryna Lagno (in 2010).[36] There is no record of 2009 event in the FIDE Calendar for that year.[37] However, the minutes of the October 2009 FIDE Congress discussed whether it should be a "proper" Championship (given the qualification scheme), and left the decision to the corresponding internal Commission.[38] For 2010, it was organized in conjunction with FIDE from the beginning.[35] However, in neither case was an arbiter's report presented to the next FIDE Congress or General Assembly, as would be expected for a World Championship and indeed occurred previously with the 2008 Blitz Championship.[39] The 2012 Arbiter's report refers to 7th World Blitz Championship thus seeming to imply that 2009 and 2010 events were indeed Championships;[40] although this report can be faulted for referring to the rapid championship of 2012 as being the 1st World Rapid Championship, which at the very least forgets Anand's official Rapid Championship in 2003. The balance of the evidence favors these Blitz Championships as being counted as official.

In 2011 there was no official blitz championship held, but FIDE was involved with the Sport Accord Mind Games blitz won by Maxime Vachier-Lagrave, with Hou Yifan winning the women's division.[41]

World Championships since 2012

Since 2012 FIDE have held joint World Rapid and Blitz Championships, with some years Women's World Rapid and Blitz Championships also being held.

In 2012 the World Rapid and Blitz Championships were held at Batumi, Georgia and Astana, Kazakhstan (Women's Championships).[43] Sergey Karjakin won the Rapid Championship.[44] Alexander Grischuk won the Blitz Championship.[45] Antoaneta Stefanova won the Women's Rapid Championship.[46] Valentina Gunina won the Women's Blitz Championship.[46]

In 2013 the World Rapid and Blitz Championships were held at Khanty-Mansiysk, Russia.[43] Shakhriyar Mamedyarov won the Rapid Championship.[47] Lê Quang Liêm won the Blitz Championship.[48]

In 2014 the World Rapid and Blitz Championships were held at Dubai, UAE and Khanty-Mansiysk, Russia (Women's Championships).[43] Magnus Carlsen won both Rapid and Blitz Championships.[49][50] Kateryna Lagno won the Women's Rapid Championship.[51] Anna Muzychuk won the Women's Blitz Championship.[52]

In 2015 the World Rapid and Blitz Championships were held in Berlin, Germany. Magnus Carlsen won the Rapid Championship.[53] He also received the privilege of playing at a dedicated Board 1 the whole time, not having to move while others did. The given reason was that Norwegian television was sponsoring the event, and moving the heavy cameras around would be too much hassle.[54] After his first round draw, he should not have been on Board 1 until Round 8 when he caught the leaders.[55] Carlsen himself later called this "weird" that board one would be reserved for him.[56] Alexander Grischuk won the Blitz Championship.[57]

In 2015, FIDE did not receive the expected 80000 euros from Agon's organization of the event, causing a budget shortfall of 55000 euros.[58][59] It was later announced that approximately 200000 euros were lost on the event.[60]

In 2016, the World Rapid Championships were held at the Ali Bin Hamad Al Attiya Arena in Doha, Qatar. Vassily Ivanchuk of Ukraine won the 2016 World Rapid Championship, while Carlsen, after defending his title with difficulty in 2015, came in third place. In the Blitz Championship, Sergey Karjakin of Russia and contender in the recently held World Chess Championship 2016 won the championship title albeit due to a better tiebrake over the second place Carlsen. Karjakin defeated Carlsen in their individual encounter. Carlsen was once again reserved board 1 for both championships. Anna Muzychuk also from Ukraine, won both the 2016 Women World Rapid and Blitz Championshipship.

At the FIDE Presidential Board meeting at the end of March 2016, they gave Agon 6 months to find an organizer for the 2017 event.[61] At the Baku General Assembly in September it was announced they had extended this deadline until the end of 2016.[62] The issue of the non-payment of the players for the IMSA Mind Games was also brought up.[62]

Criticism

Many top chess players do not take rapid, blitz and bullet chess as seriously as chess with standard time controls. Some dismissive quotes from top chess players may serve to illustrate this:

  • "Rapid and blitz chess are first of all for enjoyment." – Magnus Carlsen[74]
  • "Playing rapid chess, one can lose the habit of concentrating for several hours in serious chess. That is why, if a player has big aims, he should limit his rapidplay in favour of serious chess." – Vladimir Kramnik[75]
  • "Yes, I have played a blitz game once. It was on a train, in 1929." – Mikhail Botvinnik[75]
  • "He who analyses blitz is stupid." – Rashid Nezhmetdinov[75]
  • "Blitz chess kills your ideas." – Bobby Fischer[75]
  • "To be honest, I consider [bullet chess] a bit moronic, and therefore I never play it." – Vladimir Kramnik[76]
  • "Blitz – it's just a pleasure." – Vladimir Kramnik[77]
  • "I play way too much blitz chess. It rots the brain just as surely as alcohol." – Nigel Short[78]
  • "Blitz is simply a waste of time." – Vladimir Malakhov[79]
  • "[Blitz] is just getting positions where you can move fast. I mean, it's not chess." – Hikaru Nakamura[80]
