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 introduced to it by 鳥星雨 and taught from scratch by Kyuu. Yuuki later learned more strategic mahjong play from ペンギンヒーロー and もふもふ藍, members of Chicago Area Mahjong. 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 occasionally plays online with the Tenhou Tuesday group. In addition, Yuuki has met and played with members of USPML.

Yuuki plays as the Vanguard of Northwestern University Riichi Mahjong club's competitive mahjong team, where he was the top scorer in the club's inaugural team tournament hosted on Tenhou, with which the NU Team won.

Yuuki is an avid fan of Kobayashi Ritz's Saki series, where his favorite character is Senriyama's Vanguard, Onjouji Toki. Subsequently, he also plays as vanguard. Furthermore, 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 scored in casual play, where Ippatsu Tsumo on his takame tile gave him exactly 13 Han needed for the Yakuman (Riichi, Ippatsu, Tsumo, Pinfu, Ryanpeikou, Honitsu, Dora 2, Akadora 1).

Playing Style

YuukiTheFlash has an aggressive leaning play-style, oftentimes pushing bigger hands, while not being afraid to attack for cheaper, faster ones. This attack-oriented style is shown by his average deal in rate (放銃率 - Houjuu ritsu) of around 13.8% across his two main Tenhou accounts. Yuuki's aggressive play 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 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 (副露率 - Fuuro ritsu) 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 9-07-18, 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, instead of going by probability. Toki is known for doing this with her 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 play, with instances including his chase of 2 Riichis (one was 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 his Ippatsu Tsumo after the Riichi got him exactly 13 han.

Yuuki's play has also seen heavy influence from Matsumi Kuro, Achiga's Vanguard in the Saki series. Kuro is hailed as Achiga's Dragon Lord due to her ability to draw every dora tile in the game. However, because Kuro values these dora highly, she refuses to discard any of them, breaking tenpai many times while adding more dora to her hand. Likewise, despite Yuuki not having the power to draw all the dora, he also tends hold onto them, opting to break better waits in favor of dora tanki.

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 include Yuuki getting hit by Chankan 搶槓 while trying to to rinshan, 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, forcing Yuuki to pay the dealer penalty plus his riichi stick.

Yakuman Count

As of 11-07-2018, YuukiTheFlash's Yakuman count is at 8 (4 via Tenhou.net and 4 on real tiles). Only Yakuman scored in 4-Player are counted. His Yakuman completion list includes: Daisangen, Kokushi Musou, Shousuushii, Suuankou Tanki, and Kazoe Yakuman.

Real Tiles

Date	Yakuman	Location	Notes	Source
06-20-2018	Kokushi Musou 国士無双	Northwestern University Riichi Mahjong Club Play	Ron: Yuuki's first Yakuman on real tiles, ron on the final 9m, ending game in East 1. Kyuu (Kamicha) had a Yakuman hand as well.	[17]
09-01-2018	Kazoe Yakuman 数え役満	Casual Play with Friends	Tsumo: "Toki Kazoe" - Ippatsu Tsumo on takame for exactly 13 han (Riichi, Ippatsu, Tsumo, Pinfu, Ryanpeikou, Honitsu, Dora 2, Akadora 1).	[18]
10-10-2018	Suuankou Tanki 四暗刻単騎	Northwestern University Riichi Mahjong Club Play	Ron: Yuuki's second ever Oya Yakuman, a gyakutan to take first after entering Oorasu in 4th at 17.1k. This was also the second ron called in the entire hanchan, (the first being called the turn before in South 3, when Yuuki ronned first place Kamicha with a mangan).	[19]
11-07-2018	Suuankou Tanki 四暗刻単騎	Northwestern University Riichi Mahjong Club Play	Ron: Yuuki's second Suuankou Tanki, coming nearly a month after his first. Interestingly enough, all of Yuuki's Suuankous to date have been won off of rons. The directed yakuman in South 2 ended the game by busting toimen, allowing Yuuki to pass Shimocha who was first at 43.8k.	[20]

Yaku Highlights

These are some of the more interesting yaku and yaku combinations (non-Yakuman) YuukiTheFlash has scored.

Date	Location	Yaku(s) of Interest	Value	Notes	Source
06-19-2018	Tenhou 7863	Chankan, Ippatsu	8000	Yuuki's first Chankan ever scored happened to be paired with his favorite yaku, Ippatsu. The winning mangan in Oorasu allowed him to take second.	[21]
07-17-2018	Tenhou 上級	Hatsu, Honitsu	5200	Almost a Ryuuiisou, but was not because of the 1s in Yuuki's winning hand. He wanted to decline the ron on Shimocha to get in tenpai for Ryuuisou with a 2s tanki, but had autowin turned on. From then on, Yuuki always has autowin turned off when playing on Tenhou.net.	[22]
08-07-2018	Tenhou 7863	Ryanpeiko, Chanta	18000	Yuuki had a Chanta haipai and later declined a Chiitoitsu tenpai by dropping an aka 5s to go for Ryanpeiko with Chanta. His wait was a kanchan 8m with one already out and another in his hand. Despite this, he decided to riichi and ended up tsumoing the 8m for an oya haneman.	[23]
09-07-2018	Tenhou 3003	Rinshan Kaihou, Haku	3900	Yuuki was in tenpai for a Haku nomi, with a bad kanchan wait on the 2m. After drawing the fourth Haku, he decides to Kan (which usually is not good for him), and tsumos the 2m to complete the Saki special, Rinshan Kaihou 嶺上開花. In hindsight, there were only two 2m tiles left, and because of Yuuki's generally terrible kan luck, this was one for him to remember.	[24]
09-10-2018	Tenhou 上級	Toi Toi, Honitsu, Hatsu, Haku, Nan	12000	Yuuki had a haipai for toi toi with yakuhai and ponned each pair as they came out. Unfortunately, he never ended up drawing either dora (east) or a chun tile, and tanki on them, otherwise he would have been able to add Honroutou with either dora 2 or Shousangen for a Sanbaiman.	[25]

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 Yuuki double ron'd Toimen allowing Yuuki 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 Yuuki in West 1 Honba 1 to win the hanchan.	[26]
08-11-2018	Chicago Area Mahjong Club Play	Perfect Houtei Sanchahou 三家和 - One of three players to ron the houtei tile dropped by the dealer.	In South 3 Honba 1, the dealer is in last 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, Yuuki is Kamicha, who was waiting on 1, 4, 7s, a Sanmentan wait.	[27]
08-11-2018	Chicago Area Mahjong Club Play	Saki Rinshan Curse - Punishing failure to Rinshan during his dealer riichi after 2 ankans.	As dealer in East 1, Yuuki is the first in tenpai with 2 ankous in his hand, and a sanmenchan wait on 5m, 8m, and East, so he Riichi's. During his Riichi he is able to Kan twice but fails to rinshan both times. Kamicha decides to oikake after receiving many dora in her hand from the kans. She ends up tsumoing and after the uradora flips she wins a Sanbaiman, (Riichi, Tsumo, Dora 6, Uradora 4).	[28]

Onjouji Toki ‎(園城寺 怜)

This final section is dedicated to YuukiTheFlash's favorite mahjong player, Onjouji Toki (‎園城寺 怜), of the Saki series. Toki is Senriyama's Ace, playing in the Vanguard position, as she possesses the future sight ability which allows her to see several turns ahead on what tiles she or her opponents will draw. Thus, Yuuki rooted for the Senriyama team during the 71st Inter High School Mahjong Championships, where the team consisting of Onjouji Toki (Vanguard), Nijou Izumi (Sergeant), Eguchi Sera (Lieutenant), Funakubo Hiroko (Vice Captain), and Shimizudani Ryuuka (Captain) placed 5th out of 52 teams. Toki personally finished the nationals tournament scoring a total of +45.6k points, or an average of +9.12k per game, across the five recorded hanchans (two in quarters and semis, one in match for fifth) she played. From those recorded stats, Toki had an average placement of 1.40, and if Tenhou oka and uma were used, (weighted properly for the five hanchans), Toki would have an average score of +37.08. Onjouji Toki is also the main character of the manga, "Toki", a spinoff of the Saki series focusing on Toki during her elementary and middle school days.
