Not sure where you play, but 1/2 live games I have seen have the quality of 1cent/2cent on line.
Are you serious?
I actually went up to a charity poker event at a church. I was planning on playing $1/$2 (which would be a lot for me, although I could manage a loss there) but the table was full and I ended up not being able to get a seat all night. But I watched some of the play at the $10/$20 and $5/$10 tables and the play didn't impress me at all. I felt that if I had a steady paycheck and a few thousand bucks to spare, that I would have been one of the better players there. Unfortunately, I'm just a poor college students with an entire net worth (including savings and money for books) of a little over 3k. Guess I'll just keep grinding it out online and in my live games I play with friends ($.25/$.50, and pretty good quality) and keep working summers and hopefully someday I'll have enough to play some higher stakes games. I'm just not going to sit down with several hundred dollars because I know I could not handle losing it and thus would play scared.
Back to the original question, I agree. I used to just play live, we'd play 2-3 times a week, and then all of a sudden I could never find a game. I started playing online, could never win, worked at it, came to this site, started to win, and now I notice a huge difference in the quality of my live play. I think just seeing all the hands helps because you've pretty much played most situations when you play as many hands as you do online. I'm able to more easily recognize betting patterns. The one place I'd say my play takes a hit from playing online is staying focused and observant. It's easy online to pay attention to something else because the pot size, all the stacks, and the action to you is all very accessible. In a live game you cannot afford to ask for a pot count and give someone a chance to get a read, and you should know approximately each stack size, along with all possible draws, your ranges for each opponent, their image (no PT or PA HUD live) as well as your own hand and outs. I've been working at it but that's been the toughest part about adapting to live play.
