Clearly QQ+ will be in his range then, so we need to check the next most likely hand, AKs.
Where does the above equation come from?

I am also a little fuzzy on the pot odds figure. If the villian can see our cards and play perfectly, he will only call with even odds or better, which would be S:S to S+1:S, wouldn't it?

Maybe I'm math illiterate, but it has been over 15 years since I did any serious math.
