Ryūō

It can move as both a rook (hisha 飛車) and a silver (ginshō 銀将) during a turn and is one of the two most powerful pieces in shogi.

[21][22] Hiroyuki Miura won the three-game challenger playoff match for the 29th Ryūō tournament by defeating Tadahisa Maruyama two games to one in early September 2016.

Miura denied the accusations at a meeting of the JSA managing directors on October 11, and said he was withdrawing from the upcoming title match because he could not play shogi under such circumstances.

[26][27] The JSA subsequently established an independent investigative panel at the end of October 2016 to determine whether Miura had actually done anything wrong and to evaluate the appropriateness of its response to the allegations.

The panel found there was insufficient evidence to support the accusations of cheating made against Miura and that the claim that he had excessively left his seat during official games was false.

JSA president Koji Tanigawa apologized to Miura and announced he was being allowed to return to active status in January.

[31] Miura criticized the JSA in his press conference and stated that "he wonders why the association banned him from participating in the Ryu-oh championship match since there was no evidence of wrongdoing" and that "he wants things to be settled as soon as possible and that he will try hard to get back to his winning ways".

The meeting took place via teleconferencing at JSA offices in Tokyo and Osaka, and a vote was held to determine whether the five should be asked to step down.

[35][36] On May 24, 2017, Miura and new JSA president Yasumitsu Satō held a joint press conference to announce that a settlement had been reached to resolve any outstanding issues between the two sides.

Both sides acknowledged their acceptance of the findings in the independent investigative panel's report and expressed their desire to move on from the matter.

It was also announced that the JSA agreed to pay Miura an undisclosed financial settlement to compensate him for not only lost game fees, but also for the mental anguish and damage caused to his reputation.
