I agree with not using kicks, too easy to slip and being knocked over in a bum rush of multiple people while standing on one leg. I’d used my jab to keep them off me and load up my right cross or left hook to KO one at a time. I’d use my wrestling skills to keep off the ground at all cost. Hell if you end up on the ground you’re probably better off turtling up and protecting your head from the incoming foot stomps and soccer kicks.
Yes, you can carry a bottle of beer around. Done it many times!
