Is Cobra coming back for a second time?

Cheating, in my understanding, is deceiving an opponent to gain an advantage in the game. In this case, nothing like that happened. Any deception implies the hope of not being exposed; who would cheat in front of three spectators acting as judges?
I don't think there was any intention to gain an advantage either; the profit in this case was too small, it was just a small time-saving measure that would have been spent later in the game.
There was a disregard for minor (in Alex's opinion) nuances of the rules due to an inability to overcome his own curiosity.
In general, the tendency to disregard minor details and curiosity is common to many people, including myself. But in a game, the interests of two people (at least) are involved, and neither of them can decide for themselves what is a minor detail and what is not. In this regard, I believe that the rules should be followed meticulously, and if they are violated, it should be done by agreement with the opponent (at least).
Therefore, I decided not to continue this game.
I have no intention of refusing to play new games with Alex, provided that he agrees with my position regarding the rules.
