I don't have a hand to show but I'll talk it down.
Yesterday on Stars I was in a hand with two opponents. Long story short is that on the flop I had a K high flush draw. I bet out and was raised with a caller in the middle. I had 4-1 to call so I did, I hit the flush, won the pot, cheered, did backflip etc....

It got me thinking though; Lets change it up, if I was against just one opponent on the turn with the same flush draw. I am about 4-1 to hit the flush on river. If I think there is a good chance the opponent will call a bet from me or lead out with a bet after I hit the flush I will call a turn bet to me if the pot odds are 3:1 (i give myself that for implied odds).
However, do my implied odds change if there is 2 opponents? If I am on the turn with the same flush draw and the betting to me with 2 opponents gives me say only 5:2 am I theoretically correct to call? Is it generally accepted that with two players in the pot I stand to have a better chance of having at least one caller out of two if I hit the flush than if I just have one opponent and hit, thus giving me better implied odds?

Hopefully I explained that properly, I look forward to advice...
