I am sure CJ thinks he can win or he would not be playing.
Like most 10 ball matches this will come down to who is breaking better. CJ can run out most 10 ball racks (especially to the 7) where he has the first open shot.
He played Efren on a brutal table several months back and lost 15-12. That match could have easily gone the other way. Granted Efren doesn't play as well as Dennis these days, but they were playing even.
CJ might want to bring an actual break cue this time. Breaking with his playing cue won't cut it against Dennis.
