This should be a fundamental in NL, but I see players do this often.
Much less could have saved a ton in this hand-

Yeah but if the player doesn't have 88 here he can't call. What's worse is if the other guy has AA then he's really in trouble.

Am i missing something here? What is the worst hand that you call with here when he raises all-in? And wtf is this guy raising all-in with against a competent player with some BS? hmm....confused...right here!
