In E1-0, Uotani starts out with a 4-shanten hand (3-shanten for chiitoi) with a pair of 3p dora. Through the first row, Uotani draws another dora, makes some ankous and is 2-shanten by the end of the row. She advances slowly but surely in the 2nd row and at the start of the 3rd row, Uotani calls riichi on a 47m ryanmen wait. Despite there being little time to draw the winning tile, the good wait gives her a chance to get it. On Uotani’s last draw, she finds the 7m to win the hand. Revealing the 3s ankou to also be the ura dora, Uotani wins with Riichi/Tsumo/Dora 3/Ura 3 for a surprising 4,000/8,000 win.

In E2-0, Uotani starts out with a 5-shanten hand (4-shanten for chiitoi) with an ankou of 7m dora. With bad hand shapes and Okada making two early calls, Uotani’s chances seemed slim. However, Uotani managed to get to iishanten near the start of the 2nd row. In the middle of the row, Uotani gets to tenpai and stays dama on a 4m kanchan wait. Soon after, Murakami gets to tenpai and calls riichi on a 7m dora kanchan wait. Looking around the table, there are no 7m left in the wall and one 4m left in the wall, meaning that the hand is likely going to a draw. However, Murakami manages to draw the last 4m and deals into Uotani. Uotani wins the hand with Tanyao/Dora 3 for 8,000. Adding on Murakami’s riichi stick, she adds 9,000 points to her score. With the 16,000 from the previous hand, her score becomes exactly 50,000 in two hands.

Through the first row, Sonoda calls pon on the 8s, 2s and 9s and gets to tenpai on a 1s/3s shanpon wait for haneman.
At this, Kobayashi is still iishanten and will almost certainly need to throw dangerous tiles. In the 2nd row, Kobayashi calls pon on Sonoda’s thrown 5s. He takes the risk and throws the 6s, successfully surviving and getting to tenpai on a 58p ryanmen wait. He keeps pushing with the north and the east, keeping the tenpai.

Unexpected

December 10, Game 2, S4-0
In S4-0, 4th place Date is 600 behind 3rd place Katsumata and 2nd place Mizuhara is 2,600 behind 1st place Taro. Mizuhara starts out with a 2-shanten hand without the value she needs, while Date is 3-shanten with a hand looking like it will be riichi only. At the end of the 1st row, Date gets to tenpai and calls riichi on a 7p penchan wait.

Within the ippatsu turn, Mizuhara has a chance to get to tenpai. Her hand currently has no yaku and winning with riichi only would give her a 2,300 gain on Taro, not enough to advance in placement. However, a single han would do it. Mizuhara decides not to call riichi, staying dama on a yakuless 5s to look for other options.

On Mizuhara’s very next draw, she gets the red 5s and wins the hand. Because of the red dora, Mizuhara gets a Tsumo/Aka 1 win for 700/1,300 (plus Date’s riichi stick) to get an unexpected 1st.
