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.

It has nothing to do with pot size bets or 3/4 size pot bets. You know much is in the pot and how much it is going to cost to bet and stay in the pot. If this ratio is less than your hand odds, you fold.

Sorry to say Nefertite, Rule 4 and 2 is long gone with the poker conoscenti because of its innacuracy. It has been supercede by Rule 2 and 2, which reflects the odds more accurately. For example, a flush draw with 9 outs of gives 18%, (4/1) against the true odds of4.22/1

Is this what you are looking for?
Yes, for most cases is enough to remember pot size bet 33%, half pot bet 25% and anything else between.


Please don’t give inaccurate results like this, it is well known that correct number is 1/4.22222 you Need to use minimum 5 decimals not to have rounding errors in EV calculations , that is imperative.

Please expand on this topic. And regale us with a few tales of the poker "conoscenti".

This is poker ffs, who ever calculates to five decimal places, and will it make any difference. Most players will settle for 4/1 with a flush draw. Get real man!

this is what I wrote out to help me with this question
Facing bet 1/5 pot, you need to call 1 to win 6, pot odds 6:1 You need 1/7 = 14%
…bet 1/4 pot, you need to call 1 to win 5 Pot odds 5:1 You need 1/6 = 16.6%
…bet 1/3 pot …call 1 to win 4 Pot odds 4:1 You need 1/5 = 20%
…bet ½ pot …. Call 1 to win 3 Pot odds 3:1 You need 1/4 =25%
… bet 2/3 pot …. Call 2 to win 5 Pot odds 5:2 You need 2/7 = 28%
….bet 3/4 pot …. Call 3 to win 7 Pot odds 7:3 You need 3/10 = 30%
…bet pot… Call 1 to win 2 Pot odds 2:1 You need 1/3= 33%
…bet 1 and 1/3 pot 4/3, Call 4 to win 7 Pot odds 7:4 You need 4/11 = 36%
…bet 1 and ½ pot 3/2 Call 3 to win 5 Pot odds 5: 3 You need 3/8= 37.5%
…bet 1 and 2/3 pot 5/3 Call 5 to win 8 Pot odds 8:5 You need 5/13=38.4%
…bet 2 times pot, Call 2 to win 3 Pot odds 3:2 You need 2/5 = 40%
…bet 3 times pot Call 3 to win 4 Pot odds 4:3 You need 3/7 = 43%
If bet is so large pot becomes irrelevant you will approach needing 50% to call.

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.
