No, not necessarily. For the most past, when i am playing I know when someone is sharing an out with me to one half of the pot, but I will also know I have him beat to the high side. So he may think he is sucking out and winning, but I will give him a dose of reality (usually).
Basically, after the flop, I know who will win what if certain cards come up. It's a gift I have for this game. Days and weeks and months of dedication have helped me. I have to get a life outside of poker, IMO.
