On the other hand, there are people who earn their living playing poker or blackjack. It's not a game for them.
Would you say that such would be a legimate form of income generation for a christian ?
2413 Games of chance (card games, etc.) or wagers are not in themselves contrary to justice. They become morally unacceptable when they deprive someone of what is necessary to provide for his needs and those of others. The passion for gambling risks becoming an enslavement. Unfair wagers and cheating at games constitute grave matter, unless the damage inflicted is so slight that the one who suffers it cannot reasonably consider it significant.
I would say, yes if these criteria are met. I guess it hinges on what exactly is meant by "depriving" someone of "what is necessary to provide for his needs and the needs of others."
If someone is not cheating, or "enslaved" or depriving what is needed to take care of himself and family, I see no objection.
