Hello! WSOP final table event /Caro's classical tells..Hmmm..

[SittingBull]

It's heads-up when one player (unknown) makes an all-in hugh raise on the river. His chest vibrates continuously.
****************************
In another heads-up case,a player (unknown)goes all-in with a hugh raise on the river again. His chest does not experience any noticable vibration. His whole demeanor remains rather stiff.
His breathing was barely noticable.
Which player has a strong hand and which one is bluffing?
BTW,none of the oppos. was able to detect the tells.One incorrectly called the raise while the other incorrectly folded. I do not believe that any ever read up / studied Caro's Tells.
