All-in question

[Mad]

I was discussing this last night with a friend and we would like to get it straightened out.

Scenario:

The river card has been dealt and there are two players left. Player A has a $100 in chips. Player B has more chips than Player A.

Player A is first to act, he bets $10. Player B raises to $20. Now Player A goes all-in, pushing in his remaining $90. Player B calls.

Question:

If Player A wins, what's the maximum amount of money he can take home from this pot? Is it $100, $90, $80 or other?

[JeffreyGB]

If player A started with $100, then the max he can win is $100 from each of the other players in the hand. If it's heads up, the max he'd be able to win is $100.

If there had been a player C who called the $20 but folded to the all-in, A could win $20 from C and $100 from B for a total of $120.

Thanks for your reply, JeffreyGB.

So, in this heads-up situation the maximum amount Player A can win is $100. Is that $100 in total, or $100 from Player B? What I mean is, let's say there are $500 in the pot before going to the river. Will Player A just double-up his $100 anyway (getting a total of $200) and the rest of the pot going to Player B?

You can win up to what you bet from each player. (includeing you)

so

A: 100
B: 200
c: 500

A bets 20, B calls, C calls, A goes all in, B goes all in, C folds...

A has 100 in the pot
B has 200 in the pot
C has 20 in the pot

The most player A can win is 220.

100 that he placed in the pot.
100 of the 200 that player B placed in the pot.
20 that player C placed in the pot.

Make sense?

[JeffreyGB]

Mad, in the situation you are describing, yes, player A doubles up his $100 and the rest of the pot goes to player B.

let's say there are $500 in the pot before going to the river

Unless A was AI on a previous street, he would have a right to the whole pot.

A 350 - let's say A is SB for 25.
B 650 - B is in the BB, 50

pre flop A calls B checks - pot = 100

flop A bets 200, B calls - pot = 500

A now has 100 left, if he goes AI and is called the pot would be 700 and A would win the whole thing if his hand is best.

I think drmc answered this (and after rereading, I'm not sure I did correctly). If it's heads-up, A has put money into the pot on the flop/turn before the river for the pot to get up to $500. He has a right to all of that pot, plus a matching amount for what he puts in at the river.

The way to look at it is that as long as a player has chips left and has matched all previous bets, he can win the pot at that point. If he then pushes all-in, he can win at most the current pot PLUS his chip count from each of the calling players.

Ex.
A has $500
B has $1000
C has $1500

Blinds are 50/100.

All players call blinds. Pot = 300. A = 400; B = 900; C = 1400.

On the flop, A bets 200. The others call. Pot = 300 + 3*200 = 900. A = 200; B= 700; C = 1200.

On the turn, all check. Pot = 900. A = 200; B= 700; C = 1200.

On the river, A pushes for 200. B raises 200 to 400. C pushes. B calls. C immediately is returned the 500 that he had which B couldn't match. The total pot is now 2500. A can win at most 1500 of that. The rest is between B & C.

So if A has the best hand, A wins 1500.
If B can't beat A, but he can beat C, then B wins 1000.
If either B or C can beat A, then A wins nothing and the winner between B & C wins 2500.

If there had been a D with 2000 who called every bet, A's pot (which A/B/C/D all could win) would be 2000. B's would be 1500 (winnable by B/C/D). And C & D would have another pot for the additional 1000 (winnable by C/D).

Thanks Laeelin, drmcboy and JeffreyGB. It's all clear now.

When a player goes all in he is entitled to only as much from each player as he put in himself.

I give some examples:

Player A has 100
Player B has 200
Player C has 300
Player D has 400

Cards are dealt
Player A bets 25
Player B raises to 50
Player C calls
Player D calls
Player A re-raises all in (100 total)
-------
Main pot now has 250 in it (A100,B50,C50,D50)
-------

Player B re-raises all in (200 total)
-------
Main pot now has 300 in it (A100,B100,C50,D50)
Side pot 1 now has 100 in it (B100)
-------

Player C calls
-------
Main pot now has 350 in it (A100,B100,C100,D50)
Side pot 1 now has 200 in it (B100,C100)
-------

Player D re-raises all in (400 total)
-------
Main pot now has 400 in it (A100,B100,C100,D100)
Side pot 1 now has 300 in it (B100,C100,D100)
Side pot 2 now has 200 in it (D200)
-------

Player A is already all in so has no action here
Player B is already all in so has no action here
Player C calls with his remaining 100
-------
Main pot now has 400 in it (A100,B100,C100,D100)
Side pot 1 now has 300 in it (B100,C100,D100)
Side pot 2 now has 200 in it (C100,D100)
Side pot 3 now has 100 in it (D100)
-------

Player D is the only player in Side pot 3 so he wins that one by default.
Player D has a shot at all of the pots (Main, Side1, Side2)
Player C also has a shot at all pots (Main, Side1, Side2)
Player B only has a shot at Main and Side1
Player A only has a shot at Main
