In For ( poker )


1) The total action to which one player is entitled, usually when side pots are involved.
"How much is he in for?" implies that one who is all in is entitled to only a certain portion of the pot.

2) All in, and thus entitled to only part of the pot. "I'm in for the antes" means I can win only the antes if I win;
"I'm in for one bet" means I get an amount equal to one bet from each player if I win.

3) How much a player is in (How many chips a player has bought altogether. "How much you in for?"
might be an attempt by another player to find out whether that large stack of chips you have is winnings or all your own money).
