hello, well i have this doubts about some stuff.
1.- is it a sin to deceive people in this situations:
for example when you are playing poker, you deceive the others by bluffing, or like in a computer game I like where one of the characters abilities is to look like any of the other characters in order to deceive people into thinking you are on their team or are another class or player, this also has to be helped by some acting by yourself if you want the other team to buy it like using the automatic messages to confuse them and stuff.
or is it allowed because it is a thing everyone accepts since the begining, that it is part of the game to try to deceive others while the others will try to do the same, and the deceiving only affects the game.
also in the same stuff, what about the feints? like in sports or in a fight when you make it look like you are going to do something to make them do a mistake.
