Playing Style

鳥星雨 plays a slow and methodical, conservative playstyle. He focuses heavily on probability maximization as a key towards winning hands. Therefore, he relies very heavily on ryanmen and sanmenchan waits, which results in him going for the yaku Pinfu in a plurality of his hands. 鳥星雨 rarely calls tiles, and prefers to keep his hand closed. This is because he greatly values the ability to play defensively if the situation requires it. 鳥星雨 will rarely call Riichi on a poor wait, and will often times sacrifice tenpai to search for a better one, even without a valid yaku in his hand. All of this results in rather slow gameplay, leading to lower hand winrates in general.

However, 鳥星雨's specialty is defensive play. When he is ahead, he is excellent at holding onto leads. Like any good defensive player, he properly understands when to fold, and how to do so. However, his unique skill, and simultaneously his favorite play, is to deny opposing players' chances of a comeback by pushing and winning his own hands after an opposing Riichi call.

Inspired by club leaders at Waseda University, 鳥星雨 has practiced discard reading to push seemingly dangerous tiles under an opposing Riichi call and steal some wins from other players. His favorite strategy is to push hands that win off of the Riichi player's genbutsu tiles, picking off points from other players who are attempting to fold. He takes advantage of the fact that a call for Riichi not only eliminates entirely the calling player's ability to defend, but also tends to elicit folds from the remaining players. This way, he not only gains points, but crucially denies opportunities for comeback wins and gyakutens.

鳥星雨's biggest weakness is aggressive play involving fast tenpai hands. This is because of his unwillingness to call, even when it may be better to do so. This is most evident when he plays with beginners, or in the 一般 lobby of Tenhou, where although he doesn't deal in, he loses simply due to other players being faster in hitting the beginner level players. Thus, he very much dislikes playing games with beginner level players, and prefers to play with 特上 level players or better. Ultimately, he is a player that has more fun losing to skilled players than beating beginners.

Yakuman Count

Real Tiles

Date	Yakuman	Location	Notes	Source
2018/07/03	Kokushi Musou 国士無双	Waseda Mahjong Club 早稲田麻雀部	Ron: Kokushi Musou scored by houtei ron on the Hatsu. Haipai had 8 unique terminal/honor tiles. A 42.1k first place lead was acquired by South 4 Oorasu. The initial plan was to attempt a Chanta, but gradually a yakuman became a possibility. Although isshanten was achieved waiting on the East and Hatsu, a pon of Hatsu was called, and a third East tile was discarded. However, the second to last draw found the fourth and final East tile. A show of tenpai at ryuukyoku was at this point expected, but second place kamicha at 33.8k found the last Hatsu tile and pushed a ryuukyoku tenpai. The final score was a first place 74.1k.	[3]
