Hey Tim.. Only habit i have,playing online poker is to say loud to myself ''Hold'' when i am engaged to an important all-in..(especially when i am in final table)
If I get to play, I try to win as much as possible - that can become a habit I guess.
Never found anything that makes me more lucky with any sites' random number generator... or those darn shuffle machines when playing live for that matter.
While playing early and you got the nuts I don't insta-push my calls/raises. Most people early think you're weak or missed cause of it. Late you can get away with doing the same thing too if your versing somebody that is a bit of a bully and want them to call.
I noticed a thing when playing poker. Last time I visited portugal, I bought a watch. When I wore it, I was better at poker, and when I did not have it, it did not work well. So, every time I play poker, I wear this lucky clock ...
