I seem to be the only player on this website to try to adjust from live to online, rather than the opposite, and I'm I'm only 27.
I'm not part of the poker boom, or at least not as people usually define it. I didn't start after I read some random guy could win the ME after satteliting online. I hadn't seen a poker video or read a book until 6 months ago.
I started playing in Beijing, where I've been for 6 years now, around 2.5 years ago with a couple friends around the living room table on sats evening with a lot of booze. The idea was just to play a game while we were drinking. At the time we were playing Mad Dog no limit. I forgot the rules for some reason, but it's a crazy game. I think it's a 3 card draw, where the dealer decides of one card (sevens for example) that will be a wild card, it can be anything you like. Anyway, lots of fun.
After a while we started playing NLHE, almost every week. Our game took a new turn when in Nov 07 we started keeping track in a spreadsheet of all the games we play, winners, losers, total amount won/lost since Nov 07, including graphs. Every player that joined the game even only once is in the sheet. in 11 months, 45 players have played at our table. We got a casino poker table, chips... Basically we got serious. Some more than others, but keeping track pushed us to compete for the top overall spot.
Some of us got so serious that in Jan 08, we made our first deposit online. Right now, I'm the only one playing online regularily, but I hate it. Of curse I get the thrill of getting new cards each time a hand is dealt, then most of the time I don't know what to do with them. You don't have time to analyze your play right after the hand to see how bad/good you played it. It's almost impossible to have good reads on players, at least at the micro limits coz you don't know the players. Hand is over? Bam you have a new one and the timer is already screaming for you to play faster!
Live on the other hand, you have time. Time to analyze your latest play. Time to analyze your opponents. I read online players saying it's slow, you don't play enough hands... get bored. Say what? the more time you have, the more you can play thinking poker rather than probability poker. You get to talk to people too, or listen to people as I don't talk much at the table. You actually get to enjoy the game.
I'm a total amateur, never played in a tourney that had more than 30 entrants. I live in a country where gambling is harshly punished, but I will work on my live game more than online. I will go to Macau as often as I can, and I will try my best to continue building my bankroll to be able to play major tourneys. I will also however try to work on my online skill, because it is the only way for me to qualify cheap in a live tournament.
