I've never understand the "moves" game at the highest levels. When Corey tried such things in the past it didn't make sense to me either. The math just doesn't add up. I know Alex won the previous match but I really have no idea how. What's a reasonable advantage to give to Alex in a 10 ball rack where he sort of safe breaks? 60 percent would be very high if you ask me. In exchange, he gives up any chance of stringing racks together, while his opponent can. Lower his percentage down to 55% and it becomes a strategy only for those who are mathematically challenged.
Pretty sure there's a SVB vs Corey match that points out the futility of this strategy. Corey attempted to grind out racks but of course couldn't win all the safety battles, then SVB would just break and run, and string racks together.
I don't even know if Alex is employing this tactic, but I know there was talk about it leading up to this match.
