Hi,

I play on several networks and I also play live.
I think that I unconsciously use different raising sizes depending on where I play, what the default value of the "raise" button is, etc...

Also, sometimes, I select a sizing following what I feel to be good, and later I realize that it was too small.

So I'd like to know how the value of a size is calculated.

Example A :

On flop vs a Cbet.
Pot size before the CB = P
Cbet size = C

What is the formula for a pot size raise?
What is the formula for a 50% pot size raise?
What is the formula for a 75% pot size raise?

Example B :

I am BTN and the CO opened preflop.
Pot size before the OPR = P
OPR size = O

What is the formula for a pot size raise?
What is the formula for a 50% pot size raise?
What is the formula for a 75% pot size raise?

Example C :

I am SB and the CO opened preflop.
Pot size before the OPR = P
OPR size = O
But now there's the SB post to take into account I guess.

What is the formula for a pot size raise?
What is the formula for a 50% pot size raise?
What is the formula for a 75% pot size raise?

Example D :

I am BB and the CO opened preflop.
Pot size before the OPR = P
OPR size = O
Now there's the BB post to take into account.

What is the formula for a 50% pot size raise?
What is the formula for a 75% pot size raise?


I start this thread to succeed in understanding precisely how the raise sizings are calculated in poker, so please don't tell me to raise 3x and it'll be fine, or things like that, because this is more or less how I already think and I realize that in some spots, this is not accurate enough.

Thanks

I don't really understand your question. The formula for the a pot sized raise is "tally up the size of the pot, and then raise that much"

If the pot is $10, and you want a pot sized raise, raise $10. If you want a half-pot sized raise, raise $5, because $5 is half the pot

I am talking about spots were I face a bet and I want to raise.

In every example, the final sizing depends on Villain's bet size and the pot size before Villain's bet.

Its easier to think of it as a two step process:

1. you call villain's bet
2. then you tally up how much is in the pot and raise that amount

So if you're playing a .5/1 PLO game, and are first to act, first you call the 1. Then there is 2.50 in the pot so you "raise" that amount, as in put it on top of your initial 1, making your open size 3.50.

"the pot" includes villian's bet and your call. So a pot sized raise is that much.

This question comes up from time to time.

Here is a link that explains a couple of common situations and the formulas needed therein to determine the maximum amount you can raise.

Have to bump this kinda old thread, but in that article and all over the internet I can find the formula for a pot-sized raise:

r = 3*b + p

p - pot before opponents bet
b - opponents bet
r - our raise

But in reality if Hero has bet out that amount doesn't count as a part of the pot before opponents raise which is blowing my mind. How this isn't a part of the formula?

Formula should be like r = 3*b + (p-v), where v= Hero's bet <--- I can't prove this being correct by math.

Not trying to be a smartass, just wanna make this clear for myself. The original formula works when Hero hasn't bet, but facing a raise that formula doens't work anymore since the first bet isn't calculated in the pot before opponents bet.

See this screenshot and if you calculate that 200 as a part of the pot before opponents bet the formula doesn't work anymore.



So I would like to know the correct formula calculating the pot-sized raise.

simply this
189 + 100 + 200 +300 = 789
raise size: 100 + 789 = 889
total bet = 200 + 889 = 1089


pot 189
hero bet 200
vilain raises to 300

1: call 100
2: we have now 300 in front of us + 789 for pot size


ALSO: The article states:
Raising TO pot size

r = 3 * 300 +189
r = 1089

so hero has to raise TO 1089


For raising BY potsize please see examples 4 and 5 in the article or several of the above responses
