The wide variety of poker games is available in a poker room and to be precise we need to say that each poker room is meant for one poker variant. If all poker tables were assembled in a single poker room, it would have been difficult for the player to decide on what they want, rather having just one variant in a poker room and naming the poker room based on the variant that is being offered by the poker room eases the selection for the poker room for a typical player.
If the poker room does not offer the kind of poker variant you are interested in or if the poker room does not offer the kind of betting limit that you can afford, you need to better play in some other poker room rather than playing there because you are impatient to search for the next poker room.
Just like you will have to wait for a good starring hand to play any poker game effectively, you need to patiently wait to play in the poker room that is most suitable for you even if you are put in the waiting list. Some people get annoyed to wait anymore, they might be experts in holdem pot limit, but they will jump in to no limit because they are impatient to wait for the poker room with pot limit in which they are in the waiting list. This kind of hurried playing can cause a loss.
It is true that poker players should play any poker variant in a brilliant way, but it actually takes years of playing to master the various betting limits of the same poker variant. The strategies for limit holdem are lot different than no limit and pot limit. There is going to be no big offensive if a no limit player will play in a poker room that is offering pot limit, but unless they are experienced with strategies they are likely to miss on the performance. For the security of the bankroll, it is better to play in a poker room for the variant and betting structure that one can best manage with their skills. Every poker room is not the right cup of tea for everyone.
When you choose a poker room choose the game that you are most expert in playing, if you want to get a quick money winning look for the poker room that is of your choice with fishes as the opponents, you can make some good bucks against them , but also expect some shocking bad beats when luck is much on the crap players side.
