This argument makes no sense. People throw away quads because they sense something or get scared. By a small fraction cards aren't the winning factor in poker.
We're talking about pre-flop actions. It's literally impossible to throw away quads pre-flop in hold-em. You may be thinking about a different form of poker.
np, I was probably sloppy in my description. In the hand, two players hold AKo, there's another deadcard king in a folded hand, and Postle calls a all-in pre-flop with 54o. That's a +EV call, but only because of the exact combination of cards held by multiple players. There's no way a tell can give him this information.
Maybe saying "opponents have [2 cards not 5]" indicates pre-flop? The communal cards are often referred to as what someone "has" despite being communal.
Cards aren't the winning factor... only to the extent that the winning factor is figuring out what your opponent's cards are better than they can figure out yours. Knowing them because you're cheating is a pretty effective way to do that!
