Great post. Now dissect these statements mathematically, they drowned in the Folding AK preflop thread when it descended into luck hell:
Thread is a bit old but I believe all the posters stating that this is largely a "math" call have missed one important part. The fact that there were six callers lead to the not unreasonable conclusion that one or more of the outs are missing. People tend to play aces and kings so I don't think it unreasonable to expect two outs to be gone. Not sure what this does to the calculations. Obviously, you can't know this but they're not all holding pocket pairs.
this is dumb
What's wrong with this idea? It's in NLHETP. I'm sure Sklansky would believe one or two of the six is holding an ace or king. The fact that they're weak, live players only increases the odds of holding an ace. They always limp with Ax. Sure, they can limp with most anything, but aces and kings are good possibilities.
Stop discussing "luck" and discuss this!

Can one assign a % to the chance that someone folded one or more of our cards?

At any rate, this % is probably negated by the % that he has a worse A himself or some random junk hand.
I believe Bob Chiaffone says something similar in one of his books ("Improve your poker"?).
