I have been re-studying my online play and have improved a little. Here's how.
I am having to be more patient and play tighter than I would like, plus if I am playing in a tournament I am seeing very few bluffs. If someone raises me or keeps calling, they usually have me beat if they already have a good size stack. Not always, but especially toward the end of a tourney, most big stacks are not just bullying. They usually have a pretty good hand.
I am raising a lot more than just calling, like everyone always tells you to but with so many people just calling, I was falling into the same habit. My biggest thing is being more patient.
Don't know if this will help anyone, since it may sound like the same old, same old to you, but it never hurts to hear some things again.
