I had this shot on the 12. I used running English, about 10:30 on the CB, about 1 tip. I was trying to go around the 2 ball three rails, coming into the shot line for the 8 in the upper right corner. I am pretty sure I hit the CB close to my intended spot, medium speed. But instead of going left off the short rail on the left, the CB made a right turn and came on the other side of the 2 ball, not even straight. It actually came off the left short rail a little bit closer to the upper long rail.

I ended up with perfect shape on the 8 in the lower side pocket, but I was surprised by the CB reaction. This is not the first time this has happened to me. I am trying to understand why.

Does the OB incur that much Cut Induced Spin as to negate the left spin I had imparted on the CB? Should I have used pure left side, rather than top left?

Thanks for your help.
