Table stakes
The rule that you can only wager the chips in front of you at the start of a hand — no reaching into your pocket mid-hand, and no being bet out of a pot you cannot cover. It is why side pots and all-ins exist, and it applies in every regulated poker game.
Frequently asked questions
What does table stakes mean in poker?
That you may only bet the chips in front of you at the start of a hand, and you can never be forced out of a pot for lacking money. It is the universal rule in modern poker, cash and tournament alike.
What happens if someone cannot cover a bet?
They go all in for what they have, and a side pot is created for the remaining players' further betting. The all-in player can win only the main pot, which is capped at their contribution matched by each opponent.
Can you add chips during a hand?
No. You may add to your stack between hands in a cash game, but never mid-hand — and money in your pocket or wallet does not play. Taking chips off the table while the game continues is also prohibited; that is ratholing.
