Instructions
Throw strikes in combinations when both fighters are standing. Mix up head and body shots so your opponent has a harder time blocking your strikes. Keep throwing long combinations of strikes and only move back periodically when your stamina decreases. It is very possible that one of your strikes will result in a quick knockout if you keep your pace up.
Stall the fight if you get rocked (in danger of being knocked out) or your stamina is dangerously low. Move away and clinch when your opponent gets close to you. If your opponent keeps attacking, try a take down to help reset your composure.
Avoid submissions. Submissions in UFC Undisputed 2009 rarely work and will not help you get a knockout quickly.
Throw hook punches and head kicks when close to your opponent. Most of the knockouts will come from a hook punch or a head kick, so focus on them whenever your opponent is not blocking.
