The original claim is that people misconceive "that poker is about lying or that you need to lie to play poker"

The claim is not that deception can be used as a strategy at all. That btw is actually an uninteresting claim. In almost all games, you can lie to your opponent and probably gain some advantage.

If I were coaching a beginner poker player, I would honestly tell them to play statistically sound poker. That's a good way to make a lot of money.
