Definition of PAT
In some poker games, such as 2-7 Triple Draw, it is possible to discard cards to get more cards. Throwing away three cards instead of one, for example, will tell our opponent that our original play was not very good, otherwise we would have kept our cards. If we decide not to change any of our cards, we are said to be PAT. The expression could be translated as "being ready". PAT is not changing any of our cards in our hands. If you play 2-7 Tiple Draw online, you will see how many cards each day has changed after each round and if a player has not changed any, you will see the phrase PAT written on that player.
PAT in chess
There is no connection with poker here, but as you will often hear the term PAT associated with the world of chess, you might as well explain what exactly it is. In chess, PAT is when a player is not in check, but every possible move he can make puts him in check. In chess, a player is not allowed to make a move that puts him in check. PAT often occurs at the end of the game when a player has only his king.
