The deep stack situation is more complicated, because you have position, "real outs" and "hidden outs". You can hit your frush, represent someting else, and once in a blue moon (lol Fnord's words) you hit your pair and can show it down. Sometimes you'll destack villain if he led with weaker draw and you both hit or the other way around. Count boat redraws, tainted boards etc. Basically you gotta play poker with that hand. Drawing from time to time with marginally incorrect odds can also set up some future wins, when you decide to float drawy board with air/gutshots/other crap with your "chasy" image.


btw. hitting 9-outer with 1 card to come is around 20%, which is 4:1 odds, not 5:1.

So, if pot is $10 and you face $10 bet in front, pure implied odds require to make $30 on next street(s). Doesn't matter, what street it is from mathematical standpoint.

Here is great article of Bob Ciaffone about playing draws:
