In chess, a grotesque is a problem or endgame study which features a particularly unlikely or impossible initial position, especially one in which White fights with a very small force against a much larger black army. [1] Grotesques are generally intended to be humorous.

A particularly extreme example by Ottó Bláthy is illustrated in the adjacent diagram. In the initial position Black has all sixteen pieces remaining and White has just a single pawn on its starting square, yet it is White who will deliver checkmate.
This position in Forsyth-Edwards Notation (FEN) is : 8/8/8/2p5/1pp5/brpp4/qpprpK1P/1nkbn3 w - - 0 1
The solution is:
The fact that the black queen must be on a1 rather than a2 when White plays Nxb3 explains why 2.h4? does not work. Similarly, if the white knight takes a more direct route to the b3-square with 8.Ng6 Qa2 9.Ne5 Qa1 10.Nxc4? Qa2 11.Na5, Black can lose a move with 11...c4! 12.Nxc4 Qa1 13.Na5 Qa2 and there is no mate. This kind of precise timing is quite a common feature in this type of problem.
The composer most closely associated with the grotesque is probably Tigran Gorgiev; here is one of his examples.
This position in Forsyth-Edwards Notation (FEN) is : 8/8/4N3/4Q3/1pp5/1p3N2/bpqp1p2/nrkrbK2 w - - 0 1

This time, White is to play and draw. This is achieved by sacrificing most of his already small force to compel Black to repeat moves:
Otherwise 2.Ne2+ leads to mate.
and Black has nothing more than a draw by repetition. Note that only the squares c4 and e5 will do for the white knight; if, for example, 4.Nd4 then 4...Nc2 allows Black to free himself (this is not possible with the knight on e5 because of Nxd3#); and if, for example, 5.Nc6 then Black can free himself with 5...Rbc1 or 5...Rdc1 (not possible with the knight on c4 because of Na3# and Ne3# respectively).

Similar play to that found in grotesques such as these may also be found in very long moremovers (problems with the stipulation "White to play and checkmate Black in no more than n moves", where n is very high, sometimes over 100), known as longmovers, of which Ottó Bláthy was also a notable composer.
To the right is a kind of problem quite closely related to these kinds of grotesques: this time it is White who has a clear material advantage, but it is difficult to make anything of it because of the locked pawn chain.
This position in Forsyth-Edwards Notation (FEN) is : 8/8/8/1k3p2/p1p1pPp1/PpPpP1Pp/1P1P3P/QNK2NRR w - - 0 1
At first glance it seems there is nothing to be done—on moves like Rg2, White cannot make progress unless Black captures—but White does have one plan: to play Qa2 at an appropriate moment in order to threaten Qxb3. Doing this immediately does not work (Black simply promotes on a1 and it is Black who wins by ...Qa2–b3–c2 mate), but there is a way:
and the connected passed b- and c-pawns will queen in short order.
The Hastings 1895 chess tournament was a round-robin tournament of chess conducted at the Brassey Institute in Hastings, England from 5 August to 2 September 1895.
Amos Burn (1848–1925) was an English chess player, one of the world's leading players at the end of the 19th century, and a chess writer.
Anderssen's Opening is a chess opening defined by the opening move:
The Wade Defence is a chess opening characterised by the initial moves:
Nolot is a chess test suite with 11 very difficult positions from real games. They were compiled by Pierre Nolot for the French chess magazine Gambisco and posted on the rec.games.chess Usenet group in 1994. Some of these positions were particularly hard to solve for chess engines at the time.
The chess endgame of a queen versus pawn is usually an easy win for the side with the queen. However, if the pawn has advanced to its seventh rank it has possibilities of reaching a draw, and there are some drawn positions with the pawn on the sixth rank. This endgame arises most often from a race of pawns to promote.
The English Defence is a chess opening characterised by the moves:
The Balogh Defense is an unusual chess opening beginning with the moves:
Deep Blue versus Garry Kasparov was a pair of six-game chess matches between then-world chess champion Garry Kasparov and an IBM supercomputer called Deep Blue. Kasparov won the first match, held in Philadelphia in 1996, by 4–2. Deep Blue won a 1997 rematch held in New York City by 3½–2½. The second match was the first defeat of a reigning world chess champion by a computer under tournament conditions, and was the subject of a documentary film, Game Over: Kasparov and the Machine.
The World Chess Championship 1889 was the second official World Chess Championship, and was between Wilhelm Steinitz and Mikhail Chigorin. It took place in Havana, Cuba. Steinitz successfully defended his world title, by being the first of the two players to reach 10½. He won the match 10½-6½.
The 1935 World Chess Championship was played between challenger Max Euwe and title-holder Alexander Alekhine. It was played in various cities and towns in the Netherlands from October 3 to December 16. Euwe was the winner by overcoming a three-point deficit as late as the ninth game.
The 1978 World Chess Championship was played between Anatoly Karpov and Viktor Korchnoi in Baguio, Philippines from July 18 to October 18, 1978. Karpov won, thereby retaining the title.
The World Chess Championship 2014 was a match between the world champion Magnus Carlsen and challenger Viswanathan Anand, to determine the World Chess Champion. It was held from 7 to 25 November 2014, under the auspices of the World Chess Federation (FIDE) in Sochi, Russia.
The Immortal Draw is a chess game played in 1872 in Vienna by Carl Hamppe and Philipp Meitner. This game is the main claim to fame of both Hamppe and Meitner, and has been reprinted widely. The variation of the Vienna Game it uses was named the Hamppe–Meitner Variation in honour of the two players. The game was played in the 19th-century Romantic style, in which rapid development and attack were considered the most effective way to win, where many gambits and countergambits were offered, and where material was often held in contempt. These games, with their rapid attacks and counterattacks, are often entertaining to review even if some of the moves would no longer be considered best by today's standards.
The 1992 match between former world chess champions Bobby Fischer and Boris Spassky was billed as a World Chess Championship, but was unofficial. It was a rematch of the 1972 World Championship match. Fischer won 10–5, with 15 draws.
The World Chess Championship 2018 was a match between the reigning world champion since 2013, Magnus Carlsen, and the challenger Fabiano Caruana to determine the World Chess Champion. The 12-game match, organised by FIDE and its commercial partner Agon, was played at The College in Holborn, London, between 9 and 28 November 2018. The games were broadcast on worldchess.com and by NRK.
The 14th season of the Top Chess Engine Championship took place between 17 November 2018 and 24 February 2019. Stockfish was the defending champion, having defeated Komodo in the previous season's superfinal.
The Berlin Defence is a chess opening that begins with the moves:
The 17th season of the Top Chess Engine Championship began on 2 January 2020 and ended on 22 April 2020. TCEC Season 16 3rd-place finisher Leela Chess Zero won the championship, defeating the defending champion Stockfish 52.5-47.5 in the superfinal.
