Being fairly familiar with limit Texas Hold 'Em (where the amounts of bets and raises are fixed at specific amounts, e.g., $2 before the flop and on the flop and $4 on the turn and river) and Omaha High/Low, I have spent most of my time playing those games for manageable limits. I started playing a the tables with 25¢/50¢ limits and worked my way up to the $3/$6 limits.
Lately, however, I have tired my hand at No-Limit Texas Hold 'Em. At first, I limited myself to tournaments. For a fixed buy-in of anywhere from $1 to $10, I could get some experience and a chance for a decent payoff. The bad thing about these, however, was that they required a big chunk of dedicated time. So, last week, I started playing the ring games where you bring in a chunk of money and play for as long as you like (or until you run out of cash).
I've been having a good run. For the last week or so, I built up enough profit to take $270 out of my poker account and back into my bank account.
Today, my luck has been incredible and I just cashed out another $500 dollars. Not quitting the day job, but it's been a nice little bonus.
