The next consideration is whether or not your favorite
games and limits regularly spread. If you love playing
Omaha, the fact that a site offers a hundred different
hold'em games doesn't do you much good. If you like
playing $2-4 limits, there's no need to play at a site
that regularly gets only $1-2 and $4-8 games.
Almost all large sites "offer" just about
every game and every possible betting limit, but offering
those games and actually having those games regularly
populated with players are entirely different matters.
Downloading software from a number of different big
sites is quick, easy, and it enables you to look not
just at what games are theoretically available, but
what games actually run at the times of day you like
Theoretically you could open accounts at a dozen or
more different cardrooms, giving you the maximum chance
to find an open seat in your game of choice at any given
moment. As a practical matter, you don't even need to
have a very large poker bankroll to take this approach,
so long as all of your rooms are quick to accept deposits
from your credit card or a service like Neteller.
