Is This Cheating?

[Howard Beale]

[ QUOTE ]
what if someone has a tell where they tap their left foot on their chair leg every time they have a big hand. you are sitting on their left and are the only person at the table who can see the tell. is it unethical to exploit this without notifying the table?

This could go on and on:

I have a lucky card protector, a sure-fire guaranty that I'll be a winner everytime. Is it cheating if I bring it on every occasion? So far I only use it once in a while because I've felt guilty.
