How would we settle a bet about it?
It's extra friction between the two balls that causes the CB to "climb" the OB - the same ball/ball friction that causes the "extra throw" we call skids. In fact, the same friction that causes normal throw, just more of it (because of chalk or other stuff between the balls).
If the object ball is allowed to slide from its position first, before it starts to roll, the friction of sitting on the cloth is out of play. Clean, waxed balls present no sitting friction, and slide before rolling.[.quote]
Clean waxed balls also have less friction between them...

In playing pool for more than 50 years, as well as working on pool tables, and all sorts of cloth over the last 38 years, one thing I've noticed over the years is balls skid more on todays cloth than they ever did on the Steven's 22oz Superweave cloth used during the 50's through the mid 80's, that's a fact.
