I got to thinking about this reading your reply about inducing bluffs. I tend to think in terms of the unchanging nature of the math of poker. Of course I adjust to the styles of play of the players at my table and try to exploit them. What I don't think about so much is trends or fashion on a more general level. I guess one reason is that regardless of trends, if I can read individual styles for each sesssion, that trumps trends. Even so, with lack of information trends should factor in.
So what are some of the more important "fashions" you see playing today and how to exploit them? These might be things you'd take into account when playing at a new table before you've had time to study individual tendencies for very long. What are some of the more important fashions we should try to be conscious of monitoring as years go by?
