WCA board has come to the conclusion that there is proof beyond any doubt that the 2007 world record holder for blindfolded solving has cheated in the blindfolded events of several WCA competitions. The conclusion of WCA board has come after extensive investigations and a number of conversations with the competitor. The competitor has not confessed.
Proof shows that the competitor cheated by peeking underneath the blindfold.
The proof consists of the analysis of videos of several blindfolded solves in WCA competitions. Many videos gave a strong indication of cheating, because of the applied complex method combined with a flawless accuracy (77 correct solves out of 77 solves). The method had the effect that many edge and corner pieces changed positions and/or orientation while solving the corners of the cube.
One video of the multiple blindfolded event in World Championship 2007 brought proof beyond any doubt. The video shows that the competitor made an error (incorrect undo of set-up moves) during the execution of a step, and that instead of correcting the error, the competitor started solving the cube again. This is only possible if the competitor would have seen that he had made a mistake. Otherwise he would either have undone his incorrect moves, or he would not have been able to solve the cube anymore.
WCA has come to the following verdict.
- - WCA has banned the competitor for three years for all WCA competitions, starting today. The competitor may appeal for reinstatement after two years, if he fully cooperates with WCA.
- WCA has changed all blindfolded solves of the competitor to the result DNF (did not finish).
- WCA has requested the competitor to return his prize money in blindfolded events to the competition organisers. The organisers can then redistribute the prize money.
WCA has come to the following measurement to prevent future cheating in the blindfolded event:
- A temporary regulation must be applied for all competitions under WCA Regulations 2007. For WCA Regulations 2008 (expected March 2008) the additional regulation will be fully integrated, including some other preventive measurements.
The regulation consists of placing a sheet of paper (or a similar object) between the face of a competitor and the cube during the solving phase. WCA is looking for a widely available multi-purpose (solving while sitting and while standing) device that would not require the judge to constantly hold the paper.
WCA wants to honour:
- - the new world record holders: Danyang Chen, Chris Hardwick (twice) and Dennis Strehlau.
- the new world champions of World Championship 2007: Rafal Guzewicz (twice) and Chris Hardwick.
- the new silver medal winners of World Championship 2007: Shotaro Makisumi, Dror Vomberg, Bernett Orlando
- the new bronze medal winners of World Championship 2007: Tyson Mao, Yumu Tabuchi, Sinpei Araki
- all others who were damaged by the cheating of the competitor.
WCA will not use the competitor’s name in communication because the competitor is still under 18 years of age. For the same reason WCA distributed a detailed report on this matter only to a small number of involved parties. We kindly request our community to support the privacy of the competitor.
WCA encourages members of our community who have suspicions of cheating by other members to contact the WCA board, instead of making public announcements and/or feeding unfriendly public discussions.
The verdict is a very difficult decision by the WCA, but an organised sport is meaningless if its rules are not enforced. WCA would like to extend gratitude to everyone who assisted in this investigation.
All members of our community are welcome to respond to this announcement on the WCA forum. All messages with personal references or hostile expressions will be moderated.
