The chapter was awesome but even though Byakuya's finisher was a bare handed attack, Tsuki should have been able to avoid it giving that he was fast enough to enter the hurtless area of Byakuya's blade repeatedly. He basically stood there and invited Byakuya to attack him.
Plus if some of you argue that he was not prepared for such an attack from Byakuya, I still don't see why he was standing there. Its no like because Byakuya was not holding his sword his bankai has disappeared if he claims to know him so well. So why was he there?
Yeah we all know he was too cocky like, "I can avoid all of your kidou, bankai and shikai attacks" yet is that enough excuse for Kubo to let Byakuya's speed suddenly seem higher than Tsuki's seeing that up till now he put us all under the impression that Tsuki was relatively faster or as fast as Byakuya at least?
