I don't see Moore causing a kd over tua that s for sure. I think tua takes it. Maybe Archie manages to catch him a few times with solid shots but not enough to hurt him. Tua drops him heavily around the 8 th after behind behind on the cards slightly.
Moore likely has things his own way against a passive and plodding Tua for a few rounds then lowers his guard and goes to sleep.
I think Tua slips into a brainless sleep walk following Moore around the ring and being outboxed all the way to a decision shut out loss.
