Spoiler for outline:

The main gist of Tacos' play is this.

In the 2nd round, she didn't call tiles so everyone thought she will be doing the same in the semis, including Suzu, who remembers playing into Yuuki a few times, and losing nearly 20K points in the East round.

In the semis, Tacos will call tiles as fast as possible, to disrupt the plans of the others who are guarding her, and also to make use of her East dominance.

Apparently, during the training camp, Tacos had practice in doing that, and Jun inferred why she did not do so in the 2nd round, and use it in the semis, is due to Hisa's instructions.

Last line of chapter: I won't let anyone spin the dice in this round!
