I just finished watching a video of a bunch of random street fights. I was not impressed, to say the least. 99% of the 'fighting' was one person grabbing the head and/or collar with the left handing and wildly swinging poorly composed strikes to the head. Occasioanly a person would attempt to slip the other over, and they both would fall, flail a bit, then either get back up or continue the above. This leads me to believe- If a person is going to fight you, he will likely go for the head. Keep your guard high, and if they rush, keep some weight off of your right foot so that you can quickly deliver a quick to the groin. If that doesnt work/the situation doesnt warrant it- Options 1) Quick strikes to the gut/kidneys, keep yourself away from the attacker. Do not let him entangle you. Hitting the face with your fist will only get you a broken knuckle. Deliver fast, sharp strikes to the throat, or open handed strikes to the neck/nose/eyes. 2) Another strategy may be to block their initial strike and go immediatly for the groin or knees. Deliver a secondary kick to the face if they jacknife in pain/go onto the knees. 3) Duck, strike to the gut then immediatly do an open palm type strike to the jaw, driving upwards. Keep your other hand up in guard. 4) Keep blocking. Wear them out, and never even need to strike. 5) Counter-strike. Block, lash out with strike. I think the important thing is to end it quickly, and do not let them 'engage' you. Aim for vital areas rather than flailing wildly. If they have you grabbed, use your feet and hands in cojunction to take them down (press with hands, pull with legs). If they are down, stomp a vital area. I know its not nearly as easy to do as to say when the blood and adrenaline are pumping, but thats why the stategies above and pretty simple. Its important to keep yourself as calm as possible- this will give you an advantage, especially over an inexperienced angry person. Dont be afraid to use kicks. It makes life easier for everyone... OK, now a disclaimer. Ive never been in a major street fight (two minor nothings and lots of sparring, a little grapling, and lots of takedowns, and tons of fights with my brother when we were younger) so i'de really like anyone with experience to add their comments. I hope my observation and thoughts were helpful.
