long run takes into account each situation. it is saying, if i am in this exact same situation against this exact same player, what is the best move I can make. i don't really see why i would have to ignore reads, for example why the long run has to ignore that this player might be a maniac or a good lag. given the sum total of all the information I have about a player, there is a move that I should make every time from now until eternity, that is the best move. short/long run really has nothing to do with that decision, except for causing $$ won to equal out with actual equity.
