No, it is not "Artificial Intelligence" but rather the abbreviation of “all in” in English that is often translated as "tapis" in French. The expression "all in" means that all chips are at risk in one move. When playing in a casino, it should be mentioned loud and clear. You have bet of your last 150 chips and you say "I am in all". The expression AI is often used when writing the history of a hand.
Example of the use of the AI expression
We are in a tournament and the players have a small tapis. One player raises preflop, another calls. On the flop, the player to talk first check. The player in the betting position and the player who has check decides to make a check-raise all in. The hand can be written as follows for the flop.
SB c-r AI
The c-r indicates that the player on the small blind has made a check-raise. The AI indicates that the options are now restricted and that players will not play a turn or river. The player's option on the button (BTN) is therefore to call and go to abattage or fold without seeing his opponent's cards and conceding him the pot.
