I noticed some differences between UFC and street fights in terms of tactics after watching some recordings of UFC matches, and I wonder why such differences exist (since those two were kind of similar).
Feints. Many self defence related websites recommends not using feints in street fights and regards them as unnecessary moves that increases risk. But sometimes UFC fighters use them in matches for reasons I am unable to comprehend. So are feints actually realistic/useful in street fights?
Variation in technique (while standing). There seems to be very little variation in technique during UFC fights while standing. Mostly jabs, punches to the left/right temple or abdomen. Is this the optimal technique for street fights? Or should one use a combination of punches, elbow strikes, palm strikes, brachial stuns, etc?
Defense & Offense. The UFC fighters seems to exchange punches blindly a lot, and the results sometimes depend on who were throwing the most punches. Is it the same in street fights (they end significantly quicker)? Is it advisable to counter this type of continuous punches with sidestepping and counterattacking?
Speed vs Strength. Some matches include both sides throwing (comparatively) slow but powerful punches. Are these punches more useful than punches that emphasize speed in street fights? Can one counter them with fast punches?
