Does anyone have an easy way of translating the number of outs to the size of raises I should be calling.
Example:
Aiming of a flush after the flop I have 9 outs (and by rule of 4 and 2) a 36% of getting it. So should I call a pot sized bet, a 3/4 size, a >pot size?
Same for the 4 outs of a gut straight, I know I have less chance but can I call a 3/4 pot or not?
I'm also aware this is going to change if more people are in the pot.
To make it easier, either convert everything to ratio or percentage method.
Ratio:
There are 47 unseen cards and 9 cards help you. So 47-9 = 38 cards (that don't help): 9 cards (do help) or 38:9 = slightly better than 4:1 odds of hitting your flush.
Next, you need to figure out the pot odds in ratio form, which is: [pot + bet]:[call]. So, if the pot is $200 and your opponent bets out $50, then its [$200 + $50]:[$50] = $250:50 = 5:1 pot odds.
If the pot odds is greater than the hand odds, then it's a profitable call. So, getting 5:1 on a 4:1 shot to hit = profitable.
Percentage*:
To calculate the chances of hitting on the turn: [Outs x 2] + 1 = [9 x 2] + 1 = ~19%
To calculate the pot odds in percentage form, its: [call]/[pot + bet + (your bet call)]. So, if the pot is $100 and your opponent bet $40, then its: [$40]/[$100 + $40 + $40] = $40/$180. $40 is greater than 20% of $180.
If the pot odds percentage > hand odds percentage, it's a fold.
*When it comes to the rule of 2 and 4:
-Only use x4 if there is no more betting after the flop. If an opponent bets all-in and you're only other one in the hand, then you can use the rule of 4 to calculate the odds of hitting on either the turn or river because you are guaranteed to see both streets.
-If there is a chance of betting on future streets, then you would use the rule of 2 to calculate the odds of hitting on flop-to-turn, then the turn-to-river.
