I think I've always been pretty good at putting myself in my opponent's place, although I'm not sure I've ever put it quite that way. I've always tried to put my opponent's on hands and tried to get a read on them as far as how they play. I try to pick up on their habits and tendencies. I do better with better players though. I've always had an easier time figuring out how good players play than bad ones. All you really have to do to understand how good players think is read several poker books. But there are no books that explain how to play like a donkey. I can figure the good players out. But every time I try to figure out what a donk is thinking, I end up getting a headache.
