Zhang Yong harbored deep resentments, feeling that he had been deceived by Yang Yi, because although he knew Yang Yi was smart, he was unaware that Yang Yi possessed an eidetic memory bordering on genius.
It's easy to say "just remember the cards," but how many people can truly memorize an entire deck? Not to mention that card counting is practically impossible in blackjack and Texas Hold'em when only a few cards are dealt. Even in a relatively simpler game like Fight the Landlord, few can clearly recall every card that's been played.
Thus, Yang Yi could only promise to teach Zhang Yong a mnemonic method. Just like starting with physical strength when training in martial arts, learning to play cards with Zhang Yong began with memorization, alongside some simple formulas to calculate odds and probabilities.
