Nobody needs to question anyone's pool credentials on this site. You have your opinion and RJ has his and neither is wrong. Pool is just fine if you're betting it up or playing for pride or funsies or anywhere in between.
Well, at lease someone understood the "point"

The "folks like Lou" meant the folks that think you need to gamble to play your best, which is false for many, many folks. Who play the same in league, for money, or at home against the ghost. They grind to the end, and many don't really even understand the term "taking a flyer" as it just does not compute in their heads
My old man, before he passed a few years ago, would play cards (a phenom at Pinochle) and pool the same way. Oh, he'd play Pinochle for everything in your pocket, he was that good....
But, he'd play the same for nothing when playing with friends and family. He didn't know any other way to play, and it was the right way. In pool, growing up, he would safety the ever living crap out of me, time and time again.
But, I learned defense wins championships. Thus, my safety game is the strongest part of my game. I wish it were pocketing balls, but playing dad, I had to hide as much as possible, and thus got stronger in that area
