Each bet must be 2x the bet before it. So, he must raise by $80.

In No Limit, there are very few betting restrictions that a player must follow. You must bet the minimum of the big blind and when raising, you must at least double the amount of the bet (or raise) of the previous better. Other than those two restrictions, you can bet any or all your chips at any time.


So the answer would be 80.

You seem to be the only one with that opinion Tooners :P

This from Wikipedia

"If someone wishes to re-raise, they must raise at least the amount of the previous raise. For example, if the big blind is $2 and there is a bet of $6 to a total of $8, a raise must be at least $6 more for a total of $14. If a raise or re-raise is all-in and does not equal the size of the previous raise, the initial raiser can not re-raise again."

Nothing about double the amount of the previous bet there then.

As has been pointed out by others, this is wrong.

Not every poker site implements the standard rules of poker. I believe this is one of the rules that Absolute Poker implements incorrectly (in addition to awarding pots to the wrong players in Razz). If the big blind is $1, and someone raises to $5, that is a raise of $4, and the smallest possible reraise should be to $9. However, I believe Absolute Poker incorrectly makes the smallest possible raise one to $10.

This isn't very important in normal play, since reraises postflop with are less than all-in are rare, and minimum reraises preflop are usually bad plays. However, this came up while I was analyzing hands from the recent cheating scandal on Absolute Poker. I looked at the bet sizes chosen by Potripper in the tournament where Potripper could see the other players' hole cards. In several situations, Potripper would make the smallest possible raise for value when his opponents were weak.

Hand 8
Board: T[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/club.gif[/img] A[img]/images/graemlins/heart.gif[/img] J[img]/images/graemlins/heart.gif[/img] 7[img]/images/graemlins/club.gif[/img]
Opponent (out of position): 9[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/diamond.gif[/img]
Potripper (in position): A[img]/images/graemlins/club.gif[/img] 5[img]/images/graemlins/diamond.gif[/img]

Pot: 960
Oppt checks, PR bets 399, Oppt raises to 1068, PR reraises to 2136, Oppt folds.

Potripper raised 1068 more instead of 669 more against an opponent he know was weak, but on Absolute Poker, that was the smallest allowed reraise.

There have been several televised reraises (postflop) to an amount less than twice the size of the raise. Here is an example in a blind versus blind battle from season 3 of High Stakes Poker:


Board: 9[img]/images/graemlins/club.gif[/img] J[img]/images/graemlins/diamond.gif[/img] A[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/club.gif[/img]

Pot: $13,400
B bet $18k, E raised $24k to $42k, B reraised $30k to $72k, E reraised $40k to $112k, B called.

Actually, that's wrong, too, even if you mean when it is your turn. If you bet or call a bet, and then someone raises all-in for a small amount, this does not give you the ability to reraise under normal poker rules. Your options are only to call the extra amount or to fold (unless someone else made a raise), although someone who had not yet called the initial bet would be able to raise.

For example, suppose player A bets $10, player B raises to $11, all-in, and players C calls $11 (raising was an option for C). Player A can call $1 or fold, but should not be able to reraise. This rule is also not implemented properly on some poker sites, and it is important to recognize whether you are vulnerable to a reraise or not if you are in C's position.

Where is this in the rules? Prove please..

Ok I think I get it. The minimum raise in any round is always either the BB or the last raise amount that round. In the next round, it resets back to the BB, right?

[/ QUOTE ]

That's right, except in Limit games. Then the minimum bet on 4th and 5th street starts at double the size of the BB.

It is in Robert's Rules of Poker, section 14.3:

"All raises must be equal to or greater than the size of the previous bet or raise on that betting round, except for an all-in wager. Example: Player A bets 100 and player B raises to 200. Player C wishing to raise must raise at least 100 more, "
