A handicap (or "odds") in chess is a way to enable a weaker player to have a chance of winning against a stronger one. There are many kinds of such handicaps, such as material odds, extra moves (i.e. the weaker player can play the first x number of moves at the beginning of the game), extra time on the chess clock, and special conditions (such as requiring the odds-giver to deliver checkmate with a specified chess piece or pawn). Various permutations of these, such as "Pawn and two moves", are also possible. Handicaps were quite popular in the 18th and 19th centuries, when chess was often played for money stakes, in order to induce weaker players to play for wagers. Today, except for time odds, handicaps are rarely seen. However, the very strong chess engine Rybka has recently played a series of odds matches against strong human players.

Purpose and types of handicaps

Contents


The purpose of a handicap, or odds, is to compensate for the difference in skill between two chess players.[1][2][3] There are many kinds of handicaps: material odds; extra moves; time odds; special restrictions (such as pion coiffé); weighting of results (such as "draw odds" - counting a draw as a loss for the odds-giver); differential stakes; and physical restrictions, such as blindfold chess.[1][4] Many different permutations of handicaps (for example, a material handicap plus time odds) are also possible,[5][6] as are countervailing handicaps (for example, a player gives up a piece, but receives one of the opponent's pieces or pawns and/or extra moves, in return).[7][8][9]

Harry Golombek gives the following list of material odds (in increasing handicap level):[10]

Note that the odds-giver plays White unless otherwise indicated, and "pawn odds" normally refers to the f-pawn (i.e. the pawn initially located on the f2-square for White, and on the f7-square for Black).[11][12]

  • Odds of the move: Weaker player plays White.
  • Two moves: Weaker player plays White and starts the game by making two moves.
  • Pawn and move: Weaker player plays White; a black pawn (typically that on f7) is removed from the board.
  • Pawn and two moves: Weaker player plays the first two moves, and Black's pawn on f7 is removed from the board.
  • Knight odds: One of the stronger player's knights is removed, usually the queen's knight on b1.
  • Rook odds: One of the stronger player's rooks is removed, usually the queen's rook on a1.
  • Rook and pawn: Stronger player's queen rook and f-pawn are removed.
  • Two minor pieces: The odds-giver chooses which two of White's knights and/or bishops to remove.
  • Rook and knight: White's queen rook and queen knight are removed.
  • Queen odds: The stronger player's queen is removed.
  • Two rooks: Both of White's rooks are removed.
  • Strong king: The king can move up to two squares in any direction.

White mates in two moves no matter what Black plays

Larry Kaufman writes that under the chess tradition of the 18th and 19th centuries, the handicap below knight odds was:

  • Pawn and three moves: White plays the first three moves, and Black plays without the f7 pawn.[13] In odds games with extra moves (Pawn and two moves, Pawn and three moves), the odds-receiver cannot move beyond the fourth rank with those moves.[14][15] Otherwise, White could win immediately with 1.e3 2.Bd3 3.Qh5+ g6 4.Qxg6+ hxg6 5.Bxg6#.[13][14]

Even with the "no moves beyond the fourth rank" proviso, Black cannot give White an unlimited number of moves. Doing so would allow White to set up the position at right, when White's dual threats of 1.Qxf7# and 1.Ned6+ cxd6 2.Nxd6# are immediately decisive.[16]

I.A. Horowitz adds to the above list the following:[15]

  • Draw odds: The smallest of these handicaps; the stronger player plays White, and draws are counted as wins for Black.
  • Queen for a Rook: A handicap between Knight odds and Rook odds; the odds-giver's queen, and the odds-receiver's queen rook, are removed.
  • Queen for a Knight: A handicap slightly greater than Rook odds; the odds-giver's queen, and the odds-receiver's queen knight, are removed.

Other forms of handicap

Time handicaps are most often practiced in blitz games. The stronger player may be given one or two minutes to play the whole game, while the weaker player receives five minutes or more. Money odds are another way of compensating for a difference in strength; the stronger player puts up some multiple (three, five, ten, etc.) of the amount of money put up by the weaker player.[17][18]

In the 16th-19th centuries sometimes the pion coiffé (or capped pawn) handicap was used, usually for players of much different playing strengths. The stronger player must checkmate with a particular pawn, which is usually marked at the start of play. The pawn cannot be promoted. Giving checkmate with any other pawn or piece loses the game. Pietro Carrera proved that in the endgame king, queen and pawn versus king (pion coiffé), a win can be forced unless the pawn lies on a central file.[citation needed] Carrera considered pion coiffé to be about equivalent to giving odds of a queen.[19]

Similarly, games have occasionally been played with a ringed piece, where a ring or band is placed around a particular piece, and the player giving odds must checkmate with that piece.[20][21][22] (See illustrative games.) This form of odds, and pion coiffé, are very difficult for the odds-giver, who cannot allow the odds-receiver to sacrifice for the capped or ringed piece or pawn.[23][24] For instance, in pion coiffé, after 1.e4 d5 2.exd5 Qxd5, Black already threatens to sacrifice the queen for the capped pawn if it is the a, d, or g-pawn, to play 3...Qe5+ followed by such a sacrifice if it is the b or h-pawn, or to play 3...Qe4+ followed by a sacrifice if it is the c-pawn.

Staunton relied on a 1617 work by Carrera in discussing pion coiffé, the ringed piece, money odds, draw odds, and the following other "eccentric and peculiar Odds":[25]

  • Checkmate on a particular square: This may mean either that the odds-receiver's king must be mated while on the specified square, or that the odds-giver's piece must administer mate from that square. Carrera considered the first of these roughly equivalent to knight odds, the second a bit less.[26] Assiac observed of the first, "This sounds like a formidable proposition, but it really isn't. All the better player has to do is reduce the game to a favorable ending. Thereafter, having promoted a pawn or two, he will find the rest easy."[27]
  • Checkmate with a pawn: The mating pawn may be any pawn, not a specified pawn, as in pion coiffé. Carrera considered this form of odds equivalent to giving odds of two pawns.[28]
  • Giving all the pieces for two moves each time: The odds-giver begins the game with only the king and pawns, while the odds-receiver has a full complement of pieces and pawns. In exchange for this, the odds-giver plays two moves on each turn, while the odds-receiver can only play one. Carrera wrote that while some considered this an even game, he thought that it favored the pieces, although the side with the pieces must play cautiously. The player with the pieces should try to eliminate the pawns, for instance by giving up two pawns for one, or a minor piece for two pawns.[29]
  • Giving the king the knight's move: The odds-receiver's king, in addition to being able to move in the usual manner, is able to move like a knight. Carrera considered this form of odds improper because it allows the odds-receiver to use his king to checkmate the enemy king from a knight's move away (for example, with the odds-receiver's king at g6 and the odds-giver's king at h8, the latter is in check and, if no legal response is possible, is checkmated).[30] Carrera considered this form of odds equivalent to giving rook and pawn odds. Because of the king's unusual power, the odds-giver requires more material than usual in order to checkmate a bare king (for example, queen and another piece, or two rooks).[30]
  • Giving the queen the knight's move: Similarly to the above, the odds-receiver's queen (rather than king) has the additional ability to move like a knight. This makes the queen very powerful, since she has the ability to administer mate without the assistance of any other pieces (for instance, an enhanced queen on h6 mates a king on h8, since Kg8 would still leave the king in check). Carrera considered this roughly equivalent to knight odds, although it varied depending on the players' strengths.[30]
  • Odds of the castled king The odds-receiver begins the game with the positions of his king and one of his rooks interchanged (e.g., king on h8 or a8, and the displaced rook on the king's square). The first way (king on h8, rook on e8) is used unless otherwise specified before the game. Carrera thought this form of odds equivalent to the player with normally placed pieces giving a little less than two pawns, or a little less than a knight if the a8-rook and king are the ones interchanged. Staunton noted that Carrera's description and examples of these odds "are not adapted to our mode of castling" since the king and rook do not end up on the same squares they would normally occupy after castling.[31]

Staunton also mentioned the following unusual forms of odds not discussed by Carrera:

  • Odds of the losing game: The odds-giver undertakes to force the odds-receiver to checkmate him.[32] (See Paris-Marseilles, correspondence 1878, given below.)
  • Additional pawns: The odds-giver permits the odds-receiver to begin the game with a specified number of extra pawns (for example, eight extra pawns).[33] Unless specially agreed, the side with the extra pawns moves first.[34]
  • Odds of queen rook in exchange for the opponent's queen knight, or pawn and move, or pawn and two moves.[35]
  • Odds of queen knight in exchange for pawn and move, or in exchange for the first two moves.[36]

History

According to Harry Golombek, "Odds-giving reached its heyday in the eighteenth century and the early nineteenth century."[10] Indeed, it was so prevalent in the 18th century that Philidor (1726–95) played the vast majority of his games at odds.[10] About fifteen percent of the known games of Paul Morphy (1837–84) are games in which he gave odds.[37]

Howard Staunton in The Chess-Player's Handbook (1847) advised inexperienced players to accept odds offered by superior players and, upon improving to the point that they can themselves give odds to some players, to avoid playing such players on even terms, warning that doing so is apt to induce "an indolent, neglectful habit of play".[38] In 1849, Staunton published The Chess-Player's Companion, a 510-page work "chiefly directed to the exposition of openings where one party gives odds".[39] Just over 300 pages were devoted to odds games: Book I (pages 1 to 185) contained games played at various odds, and most of Book V (specifically pages 380-496) discussed various types of odds, including exotic and unusual ones.[40] The late-19th century chess opening treatise Chess Openings Ancient and Modern, by Edward Freeborough and Charles Ranken, included fourteen pages of analysis of best play in games played at odds of Pawn and move, Pawn and two moves, and either knight.[41]

Macon Shibut writes that in the mid-19th century "chess was a gambling game ... . Individual matches for stakes were the focus of organized play. Matches between leading players attracted a wide following so masters often succeeded in finding sponsors to back their personal wagers."[42] However, the available sums were generally relatively meager, and travel was arduous, so the amount of money obtained in this way was not sufficient to enable professional chess players to support themselves financially."[42] Moreover, the first major chess tournament was not organized until 1851,[43] and chess tournaments remained a rarity for several decades after that.[44] With tournaments not a reliable means of making a living, odds-giving became a way for masters to entice amateurs into playing for wagers, since the odds gave the amateur a fighting chance.[1][42][45] The odds system even became the earliest rating system: amateurs were graded according to what handicap they needed to compete against a master, and were referred to as a "Rook player" or "Pawn and Move player" as we would today speak of players by their Elo ratings, e.g. "1200 player" and "1800 player".[46]

The playing of games at odds gradually grew rarer as the nineteenth century proceeded.[10] Today, odds games, except for those at time odds, have all but disappeared.[47] Shibut posits that games played at material odds became unpopular for (1) technological, (2) political, and (3) philosophical reasons. Taking these in turn, first, the introduction of chess clocks gave rise to a new way to give odds, one that has today supplanted material odds as the preferred mode of odds-giving. Second, the Soviet Union supported chess masters and sponsored chess education, but expected chess masters "to be cultural icons, not hustlers". Third, chess began to be treated in a scientific, logical way, "with an assumption of idealized 'best play' [coming] to underpin all analysis". From this perspective, a game beginning from a "lost" position becomes less interesting, even distasteful.[4] Writings by Wilhelm Steinitz (1836–1900), the first World Champion, and James Mason (1849–1905) are consistent with the last point.[48][49]

In an interview with Ralph Ginzburg published in the January 1962 issue of Harper's Magazine, future World Champion Bobby Fischer was quoted as saying that he could successfully give knight odds to any woman in the world:[50][51][52]

They're all weak, all women. They're stupid compared to men. They shouldn't play chess, you know. They're like beginners. They lose every single game against a man. There isn't a woman player in the world I can't give knight-odds to and still beat.

Fischer later claimed that Ginzburg had distorted what he had said.[53] There is no doubt that Fischer would have failed at such an endeavor.[54] World Champion Emanuel Lasker had failed at such an endeavor in 1894, losing a match at knight odds to Jackson Showalter's wife; he scored two wins and five losses.[55]

In 2001, London businessman Terence Chapman, a master-level player, played a match against former world champion Garry Kasparov with Kasparov giving odds of two pawns in each game (the pawns to be removed being different each time); Kasparov won the match by two games to one, with one draw.[56]

The very strong chess engine Rybka has recently played a series of odds matches against strong human players. On March 6–8, 2007, Rybka gave Grandmaster (GM) Jaan Ehlvest pawn odds (removing a different pawn each time), with Rybka having White in every game. Rybka won 5.5-2.5.[57] On January 8, 2008, Rybka gave GM Joel Benjamin draw odds, with Benjamin having White in all games. Rybka won six games and drew two, thus winning the match 6-2.[58] On March 7, 2008, Rybka gave pawn and move (removing a different pawn each time) to GM Roman Dzindzichashvili, drawing the match 4-4.[59] On June 8, 2008, Rybka gave knight odds to FIDE Master John Meyer, losing 4-0.[60][61] On July 6, 2008, Rybka gave Meyer odds of pawn and three moves, winning 3-1.[62][63]

Rating equivalent

Grandmaster Larry Kaufman wrote the following about the Elo rating equivalence of giving knight odds:[64]

[T]he Elo equivalent of a given handicap degrades as you go down the scale. A knight seems to be worth around a thousand points when the "weak" player is around IM level, but it drops as you go down. For example, I'm about 2400 and I've played tons of knight odds games with students, and I would put the break-even point (for untimed but reasonably quick games) with me at around 1800, so maybe a 600 value at this level. An 1800 can probably give knight odds to a 1400, a 1400 to an 1100, an 1100 to a 900, etc. This is pretty obviously the way it must work, because the weaker the players are, the more likely the weaker one is to blunder a piece or more. When you get down to the level of the average 8 year old player, knight odds is just a slight edge, maybe 50 points or so.

Kaufman has written that Kasparov could give pawn and move odds to a low grandmaster (2500 FIDE rating) and be slightly favored, and would have even chances at knight odds against a player with a FIDE rating of 2115.[65]

    There is nothing that will improve you so much as playing with good players ; never refuse, therefore, when any one offers you odds, to accept them : you cannot expect a proficient to feel much interest in playing with you upon even terms, and as you are sure to derive both amusement and instruction from him, it is but fair that he should name the conditions. It will soon happen that you yourself will be able to give odds to many amateurs whom you meet ; when this is the case, avoid, if possible, playing them even, or you are likely to acquire an indolent, neglectful habit of play, which it will be very difficult to throw off. When you cannot induce such players to accept odds, propose to play for a small stake ; and they will soon be glad to take all the advantages you can offer.

It was only during Emanuel Lasker's 1894-1921 reign as World Champion that "the institution of the chess tournament was really developed", with "half a dozen international tournaments a year and innumerable local ones".

However, time odds have replaced material as the preferred form of handicapping." Id. at 124.
  48. ^ Steinitz wrote:

    [A] learner should seek as much as possible to play on even terms with superior players. From experience and observation we feel sure that he will learn much faster in this manner than by taking odds. The latter method of practice engenders the habit on the part of the odds-receiver of exchanging pieces without any motive other than to reduce the forces. He may also with comparative impunity commit many mistakes anyone of which would surely cost him the game if he started on even terms, and the object of the student ought to be not so much to win games as to train himself to play correctly. By taking odds a players loses the opportunity to observe the finer points of play of his adversary who on account of his inferiority in force cannot always afford to adopt the best strategy and is more apt to resort to lines of play which he knows to be unsound, relying on the inability of the weaker player to perceive the correct reply. Moreover, the openings in games at odds are quite different from those adopted in even games and, therefore, the odds-receiver is not advancing in one important branch of Chess knowledge.

    Strictly speaking, odds play is somewhat foreign to the general principles of Chess, and, therefore, less conducive to improvement of the player—giver or receiver—than serious conduct of the game on proper even terms. This would be so for the weaker party, if only because correctness of development must needs be missing, the whole theory of the opening being distorted and disturbed; and it would be so, for the stronger party, if only because of the habit of speculative and unsound combination odds play so naturally induces—a habit which if once acquired is so difficult of rejection, and whose effects cannot fail to prove inconvenient to its subject, when confronted by a foeman entirely worthy of his steel, and calling for the full exercise of all his powers.
