Calling an all in below the minimum raise

[Dangermoose]

How much do you need to call an all in if it raises the pot by an amount less than the minimum raise and there are still players to act?

eg small blind (10), big blind (20), player 1 calls (20), player 2 calls (20), small blind calls(10+10-20), big blind goes all in (20+5=25). Normally we would say the minimum raise is 20. but what does player 1 need to put in to call given there are still other players to act? is it another 5 or another 20?

if it is another 20 and player 2 and the small blind call the 20 then there would be a side pot for the bibg blind and an extra 45 in the main pot i suppose...

what do you think people?

just 5 more.

But, the key here, is that the all-in does not re-open the betting.

You'll have to look for the rule yourself to be sure, but I believe if an all-in bet is a raise of one-half of the minimum bet or more, it is not re-raisable by the rest of the field.

However, if the all-in took 10 or more chips, the other players could raise on top of that.

Yeah the Dog is right!

If the short stack all in represent less then half the size of a normal raise then all players who already acted have only two options: call or fold. They can not raise again.
however if you didn't act yet, you are allowed to raise and create a side pot!
