}}&lt;br /&gt;
&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{w|Chess}} is a centuries-old board game in which two players take turns moving one of their 16 pieces to try and checkmate the other player's king (one of the pieces). When one player is in a position to capture his or her opponent's king on their next move, and the opponent has no legal move available to avoid such capture, the opponent is said to be in &amp;quot;checkmate&amp;quot;, and by definition immediately loses.&lt;br /&gt;
&lt;br /&gt;
The game, with origins around the 6th century, and with the modern rules being essentially set in the late 15th century, has a significant amount of history. The rules and traditions are well established. The knight is a piece that can only move in an L-shaped pattern (two squares in one direction, and one square perpendicular), but has the unique ability to jump over other pieces.&lt;br /&gt;
&lt;br /&gt;
The comic highlights two mistakes players often make in chess: complete fixation on the king at the cost of their other pieces, and failure to take advantage of the knight's movement patterns. At the same time this is a jab at how people sometimes oversimplify an argument when confronted with a topic they are not familiar with. Previously this was depicted in [[675: Revolutionary]] and [[793: Physicists]]. See also the {{w|Dunning–Kruger effect}}. The units in chess are widely agreed to be well-balanced, and [[Cueball|Cueball's]] criticism of the knight shows an obvious lack of knowledge of the knight's potential.&lt;br /&gt;
&lt;br /&gt;
Given the long history of chess, a significant amount of writing and research has been dedicated to the game and its strategies. This is inadvertently mocked by Cueball who naively suggests it would be trivial to make a list of all situations in which a piece would move backwards (called a &amp;quot;retreat&amp;quot; in chess). Such a list — at least a partial one — certainly does exist, as do lists of numerous other chess moves and situations.&lt;br /&gt;
&lt;br /&gt;
Cueball's friend, a guy with {{w|knit cap}} (see the [http://xkcd.com/1112/info.0.json official transcript]) proceeds to demonstrate Cueball's lack of knowledge by beating him in four moves, which typically would only occur when an experienced player plays a novice. The checkmate depicted is likely the {{w|Scholar's mate|scholar's mate}}, or the {{w|Fool’s mate|fool’s mate}}, with both being classic checkmates in chess. It is in fact extremely easy to defend against both checkmates, moving your knights in the two knight defense would do, thus proving Cueball's inexperience. Although the scholar’s mate occurs often among amateurs, the fool’s mate is rare even among rank beginners.&lt;br /&gt;
Cueball, instead of admitting he underestimated the game, believes the failure is in the game itself. The title text indicates that Cueball attempted to suggest revisions to the rules of chess. Given that Cueball has no experience as a chess player, it is likely many of the changes are illogical or ridiculous. In the face of hundreds of years of history, it is not surprising that the chess community is ignoring them. The last major changes to the rules of chess occurred more than 400 years ago when, among other things, the pawn was given its two-space starting move and the queen was made into the most powerful piece (previously it was the weakest). The chess community's ties to the traditions of the game and their refusal to accept Cueball's suggestions are written off by Cueball as &amp;quot;{{w|emotional bias}}&amp;quot; suggesting his changes are logical, but that the community is letting their emotions cloud their rational decision making abilities, while in reality it is he who is being affected. If that can make Cueball feel any better, it could be pointed out to him that dozens and dozens of {{w|Chess variants|chess variants}} do exist out there.&lt;br /&gt;
&lt;br /&gt;
The comic may also be a jab at competitive online games whose fans call for &amp;quot;buffs&amp;quot; (power additions) and &amp;quot;nerfs&amp;quot; (power reductions) to characters they believe to be underpowered or overpowered, often with inadequate knowledge of those characters. On the other hand, some online games and multiplayer computer games in general are unbalanced since they lack centuries of history to balance themselves, unlike chess.&lt;br /&gt;
&lt;br /&gt;
The guy with the knit cap could either have been a man or a woman as from the drawing, but the [http://xkcd.com/1112/info.0.json official transcript] calls him ''knit hat guy''. In the two other cases (after this comic) where a person with hair has been shown with a knit cap it have been women. The first was [[Randall|Randall's]] wife after chemotherapy in [[1141: Two Years]] and the second time it was [[1350:_Lorenz#Knit_Cap_Girl|Knit Cap Girl]] in [[1350: Lorenz]]. Two Cueballs have also been shown using knit caps in [[1321: Cold]].&lt;br /&gt;
&lt;br /&gt;
==Transcript==&lt;br /&gt;
:[A guy wearing a knit cap over short black hair is sitting down at a computer touching the keyboard with one hand. Cueball is standing behind watching the screen.]&lt;br /&gt;
:Laptop: ''*Move*''&lt;br /&gt;
:Cueball: Why'd you move your knight away?&lt;br /&gt;
&lt;br /&gt;
:[Knit cap turns around and rests an arm on the chair looking at Cueball who holds out both arms.]&lt;br /&gt;
:Cueball: Just think ''logically''. The goal is checkmate, so you should always move pieces ''toward'' the other player's king.&lt;br /&gt;
&lt;br /&gt;
:[Closeup of Cueball holding a hand to his chin.]&lt;br /&gt;
:Cueball: I guess occasionally you need to move backward, but it'd be trivial to make a list of those circumstances and-&lt;br /&gt;
&lt;br /&gt;
:[Knit cap is leaning back in chair facing Cueball, panel is so slim that the lap top is not included.]&lt;br /&gt;
:Knit cap: Have you ever ''played'' chess?&lt;br /&gt;
:Cueball: Not much, but—&lt;br /&gt;
:Knit cap: Wanna?&lt;br /&gt;
:Cueball: Uh, ok.&lt;br /&gt;
&lt;br /&gt;
:[Knit cap sitting and Cueball standing is playing chess with a board standing between them on a very small table or a four legged stool. The board extends quite far out on either side. Their moves are indicated above with four towards knit cap and three towards Cueball. It is clear both from this and from the pieces visible on the board that knit cap is playing white]&lt;br /&gt;

:Knit cap: Checkmate.&lt;br /&gt;
&lt;br /&gt;
:[In a panel without frame Cueball is standing staring at the chess board, where there clearly are more pieces on his side of the board.]&lt;br /&gt;
&lt;br /&gt;
:[Knit cap has turned back to the laptop with both hands on the keyboard. Cueball is standing behind the chess board holding a finger up in the air.]&lt;br /&gt;
:Cueball: This game isn't very well-designed. For starters, knights are too weak...&lt;br /&gt;

Well bugger me (METAPHOR! METAPHOR!) but my current Master thesis in Computer Science could use that term without much shoehorning. (tl;dr: Binary search trees that adapt, =dynamic, can serve a query series faster than static, and the gain depends on the structure of the query series, =entropy. I prefer the good old &amp;quot;instance optimality&amp;quot;, though...) [[Special:Contributions/162.158.159.122|162.158.159.122]] 08:58, 11 June 2020 (UTC)&lt;br /&gt;
&lt;br /&gt;
This seems to tie in with the recent comic [[2315]]: ''Eventual Consistency'', which is also about entropy (in a thermodynamic(al) sense), but I guess that like the rest of the world I don't know what entropy really is, because if [[wikipedia:Entropy (information theory)|entropy]] is a measure of how &amp;quot;surprising&amp;quot; a variable is, why is everything being flat and spread out evenly called a state of maximum entropy? Everything being the same doesn't sound very surprising to me... --[[User:IByte|IByte]] ([[User talk:IByte|talk]]) 09:08, 11 June 2020 (UTC)&lt;br /&gt;
::Because entropy is the ''inverse'' of how &amp;quot;surprising&amp;quot; or organized or full of information a system is. [[User:Bugstomper|Bugstomper]] ([[User talk:Bugstomper|talk]]) 09:27, 11 June 2020 (UTC)&lt;br /&gt;
::It's not about &amp;quot;surprising&amp;quot; but about an even spread of probability, so for matter a complex molecule has less entropy than a smaller molecule because the atoms are held in place, and if the quarks in the atoms aren't even held together in subatomic particles then that is ultimate entropy. For information having more possible choices for the message or password spreads the probability of any one occurrence around more possibilities. If it is narrowly defined it has low entropy because the probability is concentrated in a few items.[[Special:Contributions/162.158.75.104|162.158.75.104]] 13:53, 11 June 2020 (UTC)&lt;br /&gt;

I can think of a number of cases where &amp;quot;dynamic&amp;quot; would be a bad thing, but not necessarily pejorative. The structure of a building had better not be dynamic (think &amp;quot;sudden energetic disassembly&amp;quot;), and when my (salaried, should be steady) paycheck becomes dynamic, I have to talk to HR. Can someone come up with a pejorative? [[Special:Contributions/162.158.78.212|162.158.78.212]] 11:16, 11 June 2020 (UTC)&lt;br /&gt;

As there exists such a thing as resilience by explicitness, when it comes to type system discussions in computer programming language design the term 'dynamic' can be pretty condemning. {{unsigned ip|141.101.76.204}}&lt;br /&gt;

(Looks like people aren't &amp;lt;nowiki&amp;gt;~~~~&amp;lt;/nowiki&amp;gt;ing. My contribution starts here.)

&lt;div&gt;How does the mimic octopus manage to mimic multiple fish? Does it split it's own body up or something?

:&amp;quot;When under attack, some octopuses can perform arm autotomy, in a similar manner to the way skinks and other lizards detach their tails. The crawling arm serves as a distraction to would-be predators. Such severed arms remain sensitive to stimuli and move away from unpleasant sensations.[23]&amp;quot;[http://en.wikipedia.org/wiki/Octopus#Defense] {{unsigned ip|173.245.48.113}}&lt;br /&gt;

&lt;br /&gt;
For the record, octopus is from the Greek ὀκτάπους, a compound of ὀκτά (eight) and πούς (foot); πούς is a third declension masculine noun, whose plural is πόδες. Therefore, the etymologically correct plural of octopus should be octopodes, not (as Orson Scott Card suggests) octopoda, since πούς is not a neuter.&lt;br /&gt;
:Actually, it would be &amp;quot;octopuses&amp;quot;, as it showed up ''after'' the regularization of English plurals to a final -s. As the video in the explanation explains, someone in the Victorian Grammarian Era &amp;quot;realized&amp;quot; it was &amp;quot;Latin&amp;quot; and pluralized it as such. This caught on and still haunts us to this day. &amp;quot;Octopdes&amp;quot; was coined around the same time by a more observant someone, who realized it was actually Greek. Personally, I avoid the whole trichotomy by saying &amp;quot;octopods&amp;quot;. Unrelated etymologically, but has the same meaning and is unequivocally regular.

I had a very different impression of this comic when I first read it. I had never heard of a mimic octopus, and I assumed that the comic was making fun of calling a food dish &amp;quot;octopus&amp;quot; when it really wasn't. As in, a restaurant might feed you whatever they caught in a net and call it octopus, no matter how absurd it was. And if they ever did catch an octopus, they split it in two. Very cynical, but not nearly as cool. {{unsigned ip|108.162.246.115}}&lt;br /&gt;

I am not getting the &amp;quot;pun&amp;quot; of two mimic octopuses. Could anyone elaborate a little bit more? I never thought it as a pun, but rather implying that a mimic octopus, or any creature mirroring what it see, can only reveal its natural form by mimicking other mimic octopus. Though I think it makes sense, this is a bit different from other topics in xkcd, so I doubt it.  12:37, 22 August 2017 (UTC)&lt;br /&gt;
&lt;br /&gt;
I agree with the above comment. Where's the &amp;quot;pun&amp;quot;? &amp;quot;Two Mimic Octopuses&amp;quot; doesn't sound like any other phrase. Maybe, at a stretch, &amp;quot;too many octopuses&amp;quot;? Moreover I don't think &amp;quot;… which is the pun of this comic&amp;quot; makes sense in any way. Comics don't all have puns, and comics with puns aren't limited to one. Perhaps it's a typo for &amp;quot;the point of this comic&amp;quot; or something? I'm going to remove that clause in 24 hours unless someone comes up with a convincing justification.

I am surprised that nobody mentioned the very similar mock identification charts such as [http://i.imgur.com/4ufx1.jpg this one] or [https://imgur.com/gallery/O5jlE7U that one]. Given the silhoutetted style of Randall's drawing, I'm pretty sure he had one or both in mind. [[Special:Contributions/141.101.105.204|141.101.105.204]] 15:36, 19 October 2017 (UTC)&lt;br /&gt;

The (visual) pun is that the one image out of all of them that actually looks like it could be an octopus, is actually not a (single) octopus.  See the identification charts in the comment above for similar concept. [[Special:Contributions/172.69.62.148|172.69.62.148]] 20:38, 11 October 2019 (UTC)&lt;/div&gt;</summary>

This comic is making fun of the three-letter codes assigned to all airports. These codes are overseen by the IATA (International Air Transport Association). Some airport codes are very intuitive, taking letters from the city name (e.g., DEN for Denver). Other codes are somewhat intuitive, taking a letter or two from the nearby city name but adding an additional letter (e.g., LAX for Los Angeles). Other codes make seemingly no sense at all (e.g., ORD for Chicago's O'Hare International, due to it formerly being named Orchard Field). In many cases, the airport codes appear to have been chosen (or invented) because they are also common abbreviations and acronyms. &lt;br /&gt;
&lt;br /&gt;
If we use the table provided, Randall's friend is flying into Edwards Air Force Base and then down to whatever. This is not a typical flight{{Citation needed}}. In actuality, the friend is flying into Newark tonight and Detroit tomorrow.&lt;br /&gt;

 |-&lt;br /&gt;
 | DFW || Dallas/Fort Worth || Down For Whatever&lt;br /&gt;
 |-&lt;br /&gt;
 | DTF || not assigned || Dartford || &amp;quot;DTF&amp;quot; is an acronym used to indicate &amp;quot;Down To Fuck&amp;quot;. Dartford is a town in Kent, UK, about 10 miles SE of London.&lt;br /&gt;

 |-&lt;br /&gt;

The Idaho Falls airport is IDA, while Idaho (Boise) is BOI, so it's unclear why BOI was chosen instead of IDA.&lt;br /&gt;
 |-&lt;br /&gt;
 | IUD || Doha || Washington (Dulles) || An &amp;quot;IUD&amp;quot; is an &amp;quot;IntraUterine Device,&amp;quot; or form of birth control.&lt;br /&gt;

 | ORD || Chicago, IL (O'Hare) || Orlando || O'Hare was once known as Orchard Place/Douglas Field, hence ORD&lt;br /&gt;
 |-&lt;br /&gt;

 |-&lt;br /&gt;
 | SEA || Seattle/Tacoma or SeaTac || [Indicates Water Landing] || This is possibly a reference to the fact that &amp;quot;SEA&amp;quot; could be interpreted as &amp;quot;Sea&amp;quot;. Like some other major airports (e.g., {{w|San Francisco International Airport}} and {{w|LaGuardia Airport}}), SEA is very close to a large body of water, in SeaTac's case {{w|Puget Sound}}: thus, missing the airport may end up in a water landing.

 |-&lt;br /&gt;

 |-&lt;br /&gt;
 | YYZ || Toronto || Toronto Pearson || This one is correct. The band Rush are from Toronto and named an instrumental after the airport call sign. See {{w|YYZ (instrumental)}}&lt;br /&gt;
