I don't think that Chess or Go players, when they are playing Chess or Go, are dumb enough to fall for that. But when a Chess player is playing poker, bets are off! I remember a pretty good chess player who was pretty good at poker and won money locally, but after he came back from Vegas, he admitted that he realized only too late that many if not all of the other elements at the poker table were there to fleece his local winnings. It's even worse online as everything is hidden from view and executed in nanoseconds rather than the "blink of an eye". The ease of using a chess engine to assist one's play is one reason that real money chess tournaments still take place largely in the real world.
