There is no reading of opponents in black jack. The player making the flat bets is keeping a count in their head based on all the cards revealed during play. They signal the "big money" teammate when the count is high, to come place some big bets. So they are working hard keeping that count, but they are not directly playing as if they know anything. The roaming fake rich guy is.
