All-In

Also known as: All In, Allin, Shove, Jam

Committing your entire stack to the pot. You can only win as much as your **effective stack**, and the bet is capped at the smaller stack in the hand.

What All-In means

Going all-in means pushing your entire remaining stack into the pot. Once you are all-in you have no further action — you cannot bet, call or fold for the rest of the hand, you simply wait for showdown.

Capped at the effective stack

You can only win as much as you put in. The amount actually at risk is the effective stack — the smaller of the two stacks. If a deeper opponent calls, any chips of theirs beyond your stack are not in play against you.

When stacks differ → side pots

If you are all-in for less than the others, the excess forms one or more side pots contested only by the still-active players. You remain eligible only for the main pot.

All-ins dominate short-stack play: see push/fold, resteal and Nash push/fold.
