Don’t underestimate someone who, perhaps purposely, does something known to be wrong but actually is barely worse than its alternative. Making the two point with 6-4. Reraising early with 55. Other stuff from real life. They may be trying to lull you into making your own much worse mistakes.
No further explanation needed. All comments welcome.
If someone is playing a game against the house, for example blackjack, and they do something stupid like hitting 16 against the dealer’s up card of a 2, they are either impaired, there is some sort of collusion with the dealer, or they are willing to lose a small amount to sucker a bystander into thinking that they are impaired or incompetent in order to make one or more larger bets with that person in the near future.
