No-Limit means what it says: there is no cap on how much you can raise or how many times. So it surprises players when, on some hands, the RAISE button is simply not there. Almost always the cause is the same: someone went all-in for less than a full raise, and you had already acted.

What counts as a full raise

A raise must be at least as large as the previous bet or raise on that street. If the pot is opened for 100, the minimum raise is to 200 — a raise of 100. If someone makes it 300, the next minimum is 500, a raise of 200. This is the minimum-raise rule, and it is the only limit No-Limit has.

The short all-in

Now suppose you bet 100, and the next player has only 140 chips. They can go all-in for 140 — a raise of 40, less than the 100 minimum. That is allowed; a player may always put in their last chips. But it is not a full raise, and the rule says an incomplete raise does not reopen the betting for anyone who has already acted.

You bet 100. You have acted. The 140 is 40 more, so you must call 40 or fold — but you cannot raise again. Anyone who has not yet acted on this street can still raise, because they are facing the bet for the first time.

Why the rule exists

Without it, two players could collude: one makes a tiny all-in that technically “raises”, and the other, having already acted, gets a fresh opportunity to raise a third player out of the pot. The rule ensures that an action too small to be a real raise cannot manufacture a new betting round. It protects the player caught in the middle.

How to recognise it at the table

  • You have already bet or raised on this street.
  • A later player went all-in, and their all-in was smaller than the size of your bet or raise.
  • The action came back to you with CALL lit and RAISE not offered.

That is the rule working. If instead the all-in was a full raise or more, or if you had not yet acted on the street, RAISE is available exactly as usual.

The related things that are not this

You cannot “raise” when nobody has bet — that is a bet, and our table labels the button RAISE either way, since in both cases you are raising the stakes. And the big blind always keeps its option to raise before the flop even after everyone limps, because posting a blind is not acting.
