Mahjong Biography

YuukiTheFlash is an amateur Riichi Mahjong player who first picked up the game in May 2018, at a Northwestern University Riichi Mahjong club meeting, where he was taught from scratch by Kyuu. He goes by the pseudonyms of Onjouji怜 and Kikuko<3 on Tenhou. While Yuuki regularly plays club mahjong with both Northwestern University Riichi Mahjong and Chicago Area Mahjong, he also plays online, weekly, with the Tenhou Tuesday group. In addition, Yuuki has met and played with members of USPML.

Yuuki is an avid fan of Kobayashi Ritz's Saki series, where his favorite character is Senriyama's Vanguard, Onjouji Toki. Subsequently, Yuuki's favorite yaku in the game is Ippatsu 一発, and his favorite yaku combination is Ippatsu Tsumo, as it is Toki's signature hand. Although he has never scored it or seen it live, Yuuki's favorite Yakuman is Tenhou 天和 (There was a period of time where Yuuki was obsessed with Daisangen 大三元, which has since dulled after he scored it multiple times on Tenhou). Yuuki's proudest hand that he has scored is what he refers to as his "Toki Kazoe", which was a Kazoe Yakuman he scored in casual play, where his Ippatsu Tsumo on his takame tile gave him exactly 13 Han needed for a Kazoe Yakuman (Riichi, Ippatsu, Tsumo, Pinfu, Ryanpeikou, Honitsu, Dora 2, Akadora 1).

Playing Style

YuukiTheFlash has a more aggressive leaning play-style, with an average deal in rate (放銃率 - Houjuu ritsu) of around 13.8% across his two main Tenhou accounts. This aggression is more strongly reflected in his higher than average hand win rate (和了率 - Houra ritsu), of 26.2% on his Onjouji怜 account, and an overall average of 24.2% across both accounts. In addition, Yuuki tends to be more of a Menzen-type player shown by his overall high Riichi rate (立直率 - Riichi ritsu) above 21.9%, and more often than not - refuses to Damaten unless there is a clear advantage to doing so. Nonetheless, Yuuki does at times play like Atarashi Ako, a character in the Saki series who is unmatched in her speed through calling. Yuuki's call rate across his two accounts is 36.1%, which is average, but his more recent Onjouji怜 account has a high call rate of 39.1%, showing clear influence from Ako's play. (Note that this is as of 9-05-18, and credit goes to Tina for her article on how to interpret Tenhou stats).

Yuuki tries to emulate Onjouji Toki's play-style in his overall mahjong play, by attempting to predict the tiles he will draw, and building his hand based on that. Toki, also from the Saki series, is known for just that with future sight ability, which allows her to see exactly what tiles she will draw next. This makes her specialty Ippatsu Tsumo, as she Riichis when she sees that she will tsumo the next turn. While Yuuki is far from Toki's mahjong level and ability, he has shown flashes of Toki-style with play, with instances like chasing 2 Riichis (including a dealer Riichi that happened to be a Sanmenchan wait) with a dora tanki only to Ippatsu Tsumo that hand; and his "Toki Kazoe" hand where he dama'd 3 turns before Riichi and Ippatsu Tsumo after the Riichi to get exactly 13 han.

Due to Yuuki's disdain for Miyanaga Saki, the protagonist of the Saki series, who specializes in Rinshan kaihou 嶺上開花, he often rejects calling Kan. However, when he does kan, it usually is not good for him. Instances of this including Yuuki getting hit by Chankan 搶槓, and more notably a time when he called Kan twice during his dealer Riichi, with a sanmenchan wait, but not only did he fail to Rinshan both times, but the kans gave an oikake Kamicha Riichi dora 10 after she tsumos, winning her a Sanbaiman.

Yakuman Count

Unusual Highlights

These are some unusual situations that YuukiTheFlash has been a part of, while playing Riichi Mahjong.

Date	Location	Situation	Description	Source
06-28-2018	Tenhou.net	Agari Renchan Deny West Win - First to score over 30k points in West, and still not win under normal Tenhou rules.	In South 4, Shimocha tsumo'd forcing a West round, as no one was above 30k (due to the Enchousen rule). Then in West 1, the dealer (Kamicha), and myself double ron Toimen allowing me to pass 30k (going to 31.8k), while Kamicha goes to 29.9k. However, because of agari renchan, Kamicha is entitled to another hand, which he wins, passing me in West 1 Honba 1 to win the hanchan.	[11]
08-11-2018	Chicago Area Mahjong Club Play	Perfect Houtei Sanchahou 三家和 - One of three players to call ron on the houtei tile dropped by the dealer.	In South 3 Honba 1, the dealer is in last place and needed to push tenpai, despite one riichi being on the table. The dealer draws the haitei tile but is not tenpai and decides to drop the dangerous dora, which is the 4s, as the houtei tile. This prompts the 3 others players who happen to be waiting on dora to call ron, forcing a Tochuu ryuukyoku by Sanchahou, allowing the dealer to continue his dealership. In the picture, I am Kamicha, who was waiting on 1, 4, 7s, a Sanmentan wait.	[12]
