Right now I co-host a T5 tournament. A friend of mine and I started this on a whim.
The reason we go T5? A couple.
- First of all, almost everyone is an amatuer player. This is a low-stakes home game ($30 buy-in). We have a lot of people playing poker the first time in ANY format, and there's already some confusion about why they pay $30 for a buy-in and get $1500 in chips and not $30. Keeping it lower at T5 is less intimidating for a lot of people. A starting stack of T1500 is easily divisible by $30 for most people.
- The chips I have been using don't have denominations on them. They are second-hand chips (not dice ones), but I got a great deal on them (600 for $80) on a whim. Because of that, I decided the denominations the first night. I decided for T5s (whites), T20s (reds), T50s (blues) and T100s (blacks). On the first color-up we repurpose the whites to be $500, then the reds to be $1000 a few rounds later.
Again, I kind of put this together myself on a whim in one day, and didn't really have time to research what was best. I didn't know T20s and T50s weren't common denominations (and I don't really understand why... going from $5 to $25 chips makes little sense to me).
That being said, I've done a lot of research since the first time we did this 3 months ago. If our game continues to grow, I want to invest in some Majestic chips, and I will likely shift the format to a T25 one out of sheer convenience for making change.
Until then, I think T5 for super, super amateur players is the best way to go, at least for my friends.
