Oh, and just some more incentive to move up to $0.25/$0.50 (or higher) if your bankroll can afford it:
Max rake @ $0.02/$0.04 is $0.04 or 1 big bet.
Max rake @ $0.10/$0.20 is $0.20 or 1 big bet.
Max rake @ $0.25/$0.50 is $0.40 or 0.8 big bets.
Max rake @ $0.50/$1.00 is $0.50 or 0.5 big bets.
If you think that's a small difference, consider the following:
1) Most limit game win-rates are usually only in the range of 1-2 BB/100 hands.
2) You pay that rake *every pot you play*, and it adds up wicked fast.
So getting your bankroll up to the point where you can play at least $0.50/$1 will make it a lot easier for you to win, and the play is pretty equally bad all the way up to $1/$2. So if I were going to make a deposit to play LHE, I'd be depositing at least $350-$400 so I could play at least $0.50/$1.
