when he winds up with the big uppercuts, dodge and then hit him in the face 10 times, DO NOT PUNCH MORE THAN 10!
When he blinks, block the 4 body shots, then duck under the hook that follows the 4 body shots.
When he blinks again, punch him in the face until you get the knockdown, he will get back up, but get him down twice in the 2nd round, and then repeat the same process for the TKO knock down in the 3rd round.
