Hello,! Let's assume that U are at a final WSOP table...

[SittingBull]

with one oppo. Both U and ur Oppo. have about the same #of chips.
Player1 makes a hugh all-in bet on the river. His chest continues to noticably vibrate. Do U make the call or not--assuming u have a decent hand but not strong.

Let's now assume u are at a WSOP final table with one other player2.
Player2 makes a hugh all-in bet. His chest vibration is hardly noticable. His body demeanor is rather stiff,motionless.
Do U call or fold? Again ,let's say u have a decent hand,but not strong.
Hmmm I'm also assuming that both players are UNKOWNS.
