We play weekly plus a few extra sessions. We play .25-.50 with a cap of $50 for BI and reloads. We do a 4 game rotation of an orbit of NLH, PLO, a combo NLH/Omaha game we call Amarillo , and a locally developed creature we call NLH Triple Draw. We kept the stakes the same for all games.
As to adding games to your group. Do all or most of you just play poker 3-4 times a year? OR are you just talking about a game you host once a quarter? Do some or many of your group play in other home games or casinos? I ask this because if you only play poker VERY occasionally I would be very carefull about adding games like PLO to a group like that. It took our group some time and study , not to mention a lot of financial bloodshed
, to get comfortable with PLO.
So if you are casual players who only meetup rarely , I would suggest you stay with NLH. If you are regular players who attend both your games as well as lots of others then introducing PLO is a great idea that you will learn to love through the pain! LOL Good Luck to you.
