I've noticed a trend (read: I might be deceiving myself, or falling victim to variance): it seems like I make the most money when I'm new to a table, and after that the gains slow down.
Anyone else notice something similar? I'd describe it as the table is willing to try bluffs more against a new player, and if you've got the goods (or the guts) to call you can see a quick early gain.
Or, it could be a fluke...
