The '''Snyder Method''', invented by [[Anthony Snyder]] in 1982, is both a [[fewest moves]] and a [[speedsolving]] [[method]] for the [[3x3x3 cube]]. The start is similar to [[Petrus]], forming a 2x2x2 block with optional [[XCross]]. Then a variety of methods may be used to complete the rest of the F2L except for one CE. (Anthony has since added optional starts using a 1x2x3 or a 2x2x3, also with or without the cross.) Then the final CE pair is placed while simultaneously orienting and placing a minimum of one LLE. Then all LL edges are solved together with one corner. Then the [[last three corners]] are solved.

== Claimed advantages ==
A salient characteristic of the Snyder Method is to orient and permute each piece at each stage simultaneously. Anthony claims several advantages for this:
* Simultaneous orientation and permutation helps to visualize piece relationships, useful to intuitive solving.
* There is a mathematical advantage.
Furthermore, all such last-layer algorithms will be a subset of [[1LLL]], making the Snyder Method a possible candidate as an intermediate method for [[1LLL]].

Though there are many cases to first solving the LLE+1C, the more common cases can generally be solved in 6-10 turns, making it quite turn efficient.

Although the Snyder Method closely resembles the [[Petrus Method]] in its F2L approach, its last-layer method differs considerably. This last-layer method was independently proposed in 2005 by [[Kenneth Gustavsson]], who called it "Fish & Chips."

== A word about algorithms ==
Anthony found almost all of his algorithms independently and without computer aid, and claims that his method is one of the most efficient based primarily on human-generated algorithms. Anthony explained this as follows: "In the 80's there was a general stereotype that using a computer was cheating, plus [I] enjoyed thinking up [my] own algorithms." However, he plans to upgrade his method using a computer in the near future.

== Variations ==
The Snyder Method allows a number of variations to be applied wherever convenient.
* when a 2x2x3 block is not immediately apparent he will start with either a 1x2x3 or a 2x2x2, then immediately finish the 2x2x3 block with a second look, or, he puts together several CE pairs as in [[Heise]], then assembles those into a F2L minus one CE
* two or more CE may be solved simultaneously to complete the F2L faster
* the LL may be solved in 1 look rather than 2, using either a shortest-move algorithm, combination, or substitution

In the early 80's, Anthony developed a complete set of fewest-move solutions for the CE pair cases and for the [[last three corners]] cases. However, he relied more extensively on the use of combinations and exchanges to efficiently put in the LL edges + corner. He makes up for this with a large selection of approximate direct-solves on the entire LL, claiming to switch to this mode about 20% of the time.

This method requires 1-2 looks for the block+cross start, then up to 1 look each for the 1-3 CE pairs, then 1-2 looks for the last layer. Though there are a lot of looks, an attentive solver can be quite efficient, and average around 40 turns. Though a beginner will likely take a lot more than this, and a pro taking their time may get his/her average down to about 36. Many of the shorter algorithms were added throughout the 80's and 90's, and the library of LL direct solves were mostly added in the 00's.

== Publication ==
In 1981 he printed his simple solution, a 7 algorithm system that is easy to learn. It was entitled, "Tony Snyder's Simplest Solution to Solve a Rubik's Cube", and though he personally only taught a handful of people this technique, a classmate took a copy and passed it out to students in a number of schools. He has not yet put to print his advanced technique.

<small>'''Note:''' Having complete sets of short algorithms was very unusual in the 1980s (combining 2 algs in 1-look was a common solution). [[Kenneth Gustavsson]] suggested the same LL-method ('Fish & Chips') in 2005 but with [[VHF2L]] and the rest in two clearly defined steps, [[EP]] + 1 corner (36 cases, the 'fish' step) and then [[L3C]] (22 cases, the 'chips' step), this makes a 2-look [[ZBLL]], often a little more effective than [[COLL]]/[[EPLL]].</small>

== Example solves ==
Here are some of Anthony's solves.

If you have edges oriented when starting the last layer you can often do using only Sune, double Sune (or inverse and/or mirrors), J-PLL a/b or U-PLL a/b for the first look. Here are a couple of examples that show how this is done:

'''Scramble''' '''Solution'''
F U F' L2 B' U' B U L2 F U' F' U AUF to U-PLL a on the left side, (L3C 3-twist).
L' U R U' B2 U' B2 U B2 R' L U' AUF J-PLL b, (L3C 'Anti Niklas')
B' F R2 U' R2 U R2 U F' U' B U' J-PLL b, (L3C Niklas)
R2 F2 R2 U R' F2 R U' R2 F2 R U R U left side double Antisune (L' U2 L U...)
R' F U2 F U L' U L F U' F U F R U2 left side double Antisune (again!)
B L2 F' D F' D' F2 L2 B' U' y J-PLL a (setup L' before the y for [[1LLL]])
L U2 L D' B2 D L' U2 L D' B2 D L2 U' y2 left Antisune.

Sometimes more than one of these solutions are possible. Working like this solves the step in an easy 2:5 times, maybe more. It is effective, fast and OH-friendly, but recogniton for the sune/doublesune cases is horrible without loads of practice. For the cases where two opposite edges needs to be swapped [[COLL]] is a recommended alternative and for the cases with edges correct, one or two look [[L4C]].

'''Korea''' is a country in [[Asia]]. Korean cubers have held [[WCA]] world records in 4 events.

== History of cubing in Korea ==
=== Pre-WCA (2001-2005) ===
There were multiple online cubing communities in Korea, corresponding to different portal sites. The oldest cubing community, "Solving the Cube" group, existed since 2001. One other major group, KCRC, was founded in 2005 or 2006.

=== Beginning of WCA competitions in Korea (2005-2006) ===
Since 2005, the most important members of the Korean cubing community were thus split between these two groups; this is the cause of the cubing politics at the beginning of the Korean WCA competitions in 2005.

The first South Korean from Korea to speedsolve was [[Lee Jun-Kyo]], who competed in the [[World Championship 2005]]. (The first South Korean competitor was James Song in 2005, who lived in Southern California.) Upon coming back to Korea, he became the first to let known in Korea that such competitions existed. At the time, there was one big cube group, a community page in one of the Korean community websites, translating to "solving the Rubik's Cube." Jun-Kyo was a member of the group and suggested there that such competitionts should be held in Korea. The administrators of the group found members who could speak another language. One such competitotor was [[Ilkyoo Choi]].

Ilkyoo sent emails back and forth with [[Tyson Mao]] and [[Ron van Bruchem]], but there were miscommunications. Mr. Hwang, the distributor of Rubik's Cube in Korea and who worked for Seven Towns, became the first delegate. The first competition held in Korea was delegated by Mr. Hwang. The president of the KCRC lost faith in Mr. Hwang after this competition. Ilkyoo planned to hold competitions in summer 2006 with Mr. Hwang as the delegate. Because KCRC did not like the idea that Solving the Cube would host a competition, their members were not motivated in carrying out this competition, which resulted in the competition not happening. Also, in summer 2006, Ilkyoo came to the United States to study.

The Korea Cube Association was founded in early 2006, with board members from Solving the Cube and KCRC.

After this, the main Korean organizers wanted hold another competition, but with a new delegate. Coincidentally, one of the administrators of Solving the Cube group, [[Cho Won-Bang]], was planning to visit [[Europe]]. In 2006, as planned, he competed in a European competition, met Ron van Bruchem, and became a new delegate. In January 2007, KCRC hosted another competition with Cho Won-Bang as the delegate. Wong-Bang left the competition for about an hour during the competition. Because president of the KCA (who was also the aforementioned president of KCRC) did not like the fact that the delegate was from Solving the Cube, he complained about this based on the WCA regulation stating that the delegate must be at the competition at all times. Seeing this discord within the Korean cubing community, Ron proposed having a delegate from each major group. As a result, [[Choi Jae-Jung]] from KCRC became a new WCA delegate.

=== World-wide recognition (2007-2008)===
In January 2007, at KCRC2007, [[Yu Jeong-Min]] (Gungz) set the 3x3 speedsolve average (11.76) and OH single (19.34) world record. The 3x3 speedsolve average was especially greeted with surprise in the western world since it shattered [[Anssi Vanhala]]'s previous record of 13.22. The news immediately placed Korea on the map in these events. Shortly after this competition, [[Tyson Mao]] emailed Ilkyoo, offering to pay both Gungz and Ilkyoo to fly to US Nationals. However, the sponsor refused to pay for their trip because Gungz and Ilkyoo were not US citizens.

=== Further growth (2008-2011) ===
In January of 2008, the national competition was held. There were four other competitions held in 2008. The WCA regulations allow ticket system; results in one round can be used to decide qualifications for another round. The competition of January 2009 was planned to be only for those competitors who had obtained a ticket through their performances in 2008. It was during one of these 2008 competitions that [[Lee Seung-Woon]] set the OH single world record of 14.34.

=== KCA dominance (2008-2011) ===
After this, Won-Bang went to the military, so that Jae-Jung became the only delegate in Korea. Because of the close relationship between Jae-Jung and the KCA, during this time, KCA had almost complete control over official competitions in Korea. Thus, until 2011, competitions that were not hosted by KCA were not held officially since Jae-Jung refused to delegate them.

=== End of KCA, beginning free competitions (2011-present) ===
In 2011, four Korean cubers went to the World Championships in [[Thailand]] and informed [[Filippo Brancaleoni]], an Italian delegate, about the situation in Korea, that not everyone in Korea was able to organize a competition because of this polarity between KCA/KCRC and Solving the Cube. Filippo communicated the situation to the WCA Board, including Tyson. Tyson and Ilkyoo Choi worked together to solve this situation. Ilkyoo became a delegate and hosted a number of competitions in Korea, while Jae-Jung was demoted to an inactive delegate by Tyson because all recent results from Korean competitions had been sent by the KCA president rather than Jae-Jung. As a delegate, Ilkyoo was able to subvert KCA's claim on their website that KCA is the only organization allowed to host official WCA competitions in Korea.

Ilkyoo returned to Korea for a month, between December 2011 to January 2012 and held four competitions (all competition names starting with "Cubing Korea"), one a week. Numerous national records were broken at these competitions. During January 2012, KCA made an announcement that they would become inactive because they no longer had the delegate. Since Ilkyoo still studies in the US and there is no other delegate, he currently emphasizes unofficial competitions in Korea.

== Korean name transliteration ==
Transliteration of Korean names in the WCA database was changed in 2011 by Ilkyoo Choi. The original format was decided by the KCA, who allowed registration using only Korean and decided on the transliteration himself. Ilkyoo called for Korean competitors to request transliteration changes and have changes dozens of names.

== Notable cubers ==
Notable cubers from Korea include
* [[Ilkyoo Choi]]
* [[Yu Jeong-Min]]
* [[Lee Seung-Woon]]

* [[Kang Ji-Jon]]

The Korea Cube Association was founded in early 2006, with board members from Solving the Cube and KCRC.

After this, the main Korean organizers wanted hold another competition, but with a new delegate. Coincidentally, one of the administrators of Solving the Cube group, [[Cho Won-Bang]], was planning to visit [[Europe]]. In 2006, as planned, he competed in several European competitions, met Ron van Bruchem, and became a new delegate. In January 2007, KCRC hosted another competition with Cho Won-Bang as the delegate. Wong-Bang left the competition for about an hour during the competition. Because president of the KCA (who was also the aforementioned president of KCRC) did not like the fact that the delegate was from Solving the Cube, he complained about this based on the WCA regulation stating that the delegate must be at the competition at all times. Seeing this discord within the Korean cubing community, Ron proposed having a delegate from each major group. As a result, [[Choi Jae-Jung]] from KCRC became a new WCA delegate.

=== World-wide recognition (2007-2008)===
In January 2007, at KCRC2007, [[Yu Jeong-Min]] (Gungz) set the 3x3 speedsolve average (11.76) and OH single (19.34) world record. The 3x3 speedsolve average was especially greeted with surprise in the western world since it shattered [[Anssi Vanhala]]'s previous record of 13.22. The news immediately placed Korea on the map in these events. Shortly after this competition, [[Tyson Mao]] emailed Ilkyoo, offering to pay both Gungz and Ilkyoo to fly to US Nationals. However, the sponsor refused to pay for their trip because Gungz and Ilkyoo were not US citizens.

=== Further growth (2008-2011) ===
In January of 2008, the national competition was held. There were four other competitions held in 2008. The WCA regulations allow ticket system; results in one round can be used to decide qualifications for another round. The competition of January 2009 was planned to be only for those competitors who had obtained a ticket through their performances in 2008. It was during one of these 2008 competitions that [[Lee Seung-Woon]] set the OH single world record of 14.34.

=== KCA dominance (2008-2011) ===
After this, Won-Bang went to the military, so that Jae-Jung became the only delegate in Korea. Because of the close relationship between Jae-Jung and the KCA, during this time, KCA had almost complete control over official competitions in Korea. Thus, until 2011, competitions that were not hosted by KCA were rarely held officially.

=== End of KCA, beginning free competitions (2011-present) ===
In 2011, four Korean cubers went to a WCA competition in [[Taiwan]] and informed [[Filippo Brancaleoni]], a Italian delegate, about the situation in Korea, that not everyone in Korea was able to organize a competition because of this polarity between KCA/KCRC and Solving the Cube. Filippo communicated the situation to the WCA Board, including Tyson. Tyson and Ilkyoo Choi worked together to solve this situation. Ilkyoo became a delegate and hosted a number of competitions in Korea, while Jae-Jung was demoted to an inactive delegate by Tyson because all recent results from Korean competitions had been sent by the KCA president rather than Jae-Jung. As a delegate, Ilkyoo was able to subvert KCA's claim on their website that KCA is the only organization allowed to host official WCA competitions in Korea. Tyson also fired Jae-Jung.

Ilkyoo returned to Korea for a month, between December 2011 to January 2012 (all competition names starting with "Cubing Korea"), and held four competitions, one a week. Numerous national records were broken at these competitions. During January 2012, KCA made an announcement that they would become inactive because they no longer had the delegate. Since Ilkyoo still studies in the US and there is no other delegate, he currently emphasizes unofficial competitions in Korea.

== Korean name transliteration ==
Transliteration of Korean names in the WCA database was changed in 2011 by Ilkyoo Choi. The original format was decided by the KCA, who allowed registration using only Korean and decided on the transliteration himself. Ilkyoo called for Korean competitors to request transliteration changes and have changes dozens of names.

Ilkyoochoi: /* Beginning of WCA competitions in Korea (2005-2006) */

'''Korea''' is a country in [[Asia]]. Korean cubers have held [[WCA]] world records in 4 events.

== History of cubing in Korea ==
=== Pre-WCA (2001-2005) ===
There were multiple online cubing communities in Korea, corresponding to different portal sites. The oldest cubing community, "Solving the Cube" group, existed since 2001. One other major group, KCRC, was founded in 2005 or 2006.

=== Beginning of WCA competitions in Korea (2005-2006) ===
Since 2005, the most important members of the Korean cubing community were thus split between these two groups; this is the cause of the cubing politics at the beginning of the Korean WCA competitions in 2005.

The first South Korean from Korea to speedsolve was [[Lee Jun-Kyo]], who competed in the [[World Championship 2005]]. (The first South Korean competitor was James Song in 2005, who lived in Southern California.) Upon coming back to Korea, he became the first to let known in Korea that such competitions existed. At the time, there was one big cube group, a community page in one of the Korean community websites, translating to "solving the Rubik's Cube." Jun-Kyo was a member of the group and suggested there that such competitionts should be held in Korea. The administrators of the group found members who could speak another language. One such competitotor was [[Ilkyoo Choi]].

Ilkyoo sent emails back and forth with [[Tyson Mao]] and [[Ron van Bruchem]], but there were miscommunications. Mr. Hwang, the distributor of Rubik's Cube in Korea and who worked for Seven Towns, became the first delegate. The first competition held in Korea was delegated by Mr. Hwang. The president of the KCRC lost faith in Mr. Hwang after this competition. Ilkyoo planned to hold competitions in summer 2006 with Mr. Hwang as the delegate. Because KRCA did not like the idea that Solving the Cube would host the first competition, their members refused to participate in this competition.

Also in summer 2006, Ilkyoo came to the United States to study. The only person left who spoke English was a member of KCRC, who actually held a competition, the president of KCA. The president of KCRC suggested that there should be a national organization. KCA was therefore founded in 2006.

After this, the main Korean organizers wanted hold another competition, but with a new delegate. Coincidentally, one of the administrators of Solving the Cube group, [[Cho Won-Bang]], was planning to visit [[Europe]]. In 2006, as planned, he competed in several European competitions, met Ron van Bruchem, and became a new delegate. In January 2007, KCRC hosted another competition with Cho Won-Bang as the delegate.
