    Default Implied Odds Calculation

    Background:
    I don't normally play an Ax flush draw from early position, but the other players at the table were playing a lot of flops with limping or minraising pre-flop. So, I figured I could see a cheap flop with multiway action.

    I didn't have pot odds for the flop call, but, with the way listriton and jojoiswired played post flop, I felt they would continue betting hard, even if the flush hit. So, I was reasonably confident that I had implied odds to make the call.

    Now that I have had some time to analyze my hands for the week, I have been thinking about what is the minimum the two other players would have needed to bet if the flush hit, in order for me to have the implied odds to make the call.

    Is there a simple calculation for this?

    Thanks

    Thanks for the compliment!

    Why I posted was not that I was concerned with my play, rather what is the "break-even" point for the implied odds calculation (i.e., what is the minimum pot contribution the other players need to make in later streets to give you the implied odds to justify the call). If the two players had become limp noodles when the third diamond hit, and they only bet $0.50 a street or folded to an aggressive bet by me, I wouldn't have had the implied odds. The fact that they put their entire stacks in the middle, I clearly had the implied odds, but where is the break-even point in extra $$ required.

    Is it as simple as determining what the pot size would need to be to make the pot odds of the $15 flop call equal to the odds of hitting the flush (in this case an extra $7.61 over the pot size at flop if I have my math correct).

    All assistance appreciated.

    I would probably have check-raised all-in with 12 outs to the nuts and the slim possibility that my A outs are good.

    You don't need implied odds to continue here, especially with two opponents.

    You definately need implied odds to continue here, if he hits his flush on the turn and both his opponents lose he will lose money in the long run.

    For the math though lets see, the pot was at 37 dollars and you needed to put in 15 dollars so you had 2.7 to 1 pot odds and you';ll make your flush 8/47 times on the turn for 5.9 to 1 pot odds.

    So then $15 * 5.9 = $88.50, so you should need the pot to get to 88.50, which means you need to get 52 more dollars in the pot, which with two oponents already in the hand calling big bets is pretty likely.

    The gutshot straight that you've got doesn't really count because you will almost always be splitting the pot, or occasionally taking it down right away because no one has an ace.

    Somebody correct me if i've made any mistakes.

    My gut also said move in on the flop, but I don't know if you could have folded them out anyway. On the other hand, moving in probably takes care of your pot odds if you get called- if you don't, great.

    yeah the all in on the flop might have been best...

    say you call the $15 on the flop and miss... then they bet out big on the turn...what do you do now? your chances are severely reduced for making your flush and even if you do call all your check/calling could definately raise a draw flag even to the weakest player. So if it hits the river you might not get any additional action. So why even put yourself in this situation...just my opinion
