Example 3: you have AhKh. The flop comes 9h8c7d. You have 6 outs to TPTK. You also have a backdoor flush draw. A backdoor flush draw is worth about 1.5 outs, and these outs are to the nuts. Your 6 outs to TPTK, however, are less valuable than usual (usually an out to top pair should be counted around 1/2-3/4 depending on how many people in the pot ... the more people, the less the chance top pair will be good). If there are a lot of people in the pot, It is very likely at least one of them has an OESD. Add this to the chances that someone has made 2pair, a set, or will improve to 2 pair, and your TPTK outs are probably only worth a little over a third an out each. If you are heads up, however, I would give the TPTK outs at least 80% value. In that case, though, your chances of being ahead with A high are also significant, and it is unlikely that you are going to be folding. Let's be generous and give our TPTK outs a value of 2.5. Added to the backdoor flush outs, this gives us a hand worth 4 outs. A 4 out hand has a pot equity of 16.5% on the flop.
