Chihayafuru

The contrast between their behavior is what makes Chihaya so incredibly likable, and what made it so easy to hate Yumin for beating Chihaya that way last season

This is all based on the assumption that Yumin was in a 50/50 situation when she contests those cards.

-If Chihaya let Amakasu have the card 100% when she knows it was simultaneous, she'd be lying to herself.
-Similarly, if Yumin had said her strikes were simultaneous when she believes she was the faster one, she'd be lying to herself.

Also, a totally badass strategy play by Taichi. He got Retro all wound up, then made a definite fake for the card. There was no way Taichi knew which one it was, but he went so intensely for it that Retro fell for it.

I don't think he intended to make Retro commit a fault. It was just the side effect of his determination to attack Retro's side. He moved as soon as he heard "The fall", but swept upwards when he heard "wind" instead of "paddy".

Retro's fault was a bonus for him and not the intended outcome of his plan.
