wow...that's a really open question.
in competition, it depended on the competition:
wrestling, i won a lot of matches with a granby throw, although i think really i won most matches by being in better shape (this was in high school and i ran cross country the season before. most wrestlers did football. if it made it to the third round they were meat).
kickboxing i couldn't really tell you. maybe a front thrust kick after i had them staggering back. never really had a kill shot there -- just wore them down.
tournament sparring it was always preprogramming them. do a combo three times in a row, then throw another combo that starts the same but takes advantage of them trying to counter combo a.
in my few street experiences, i had good luck with wrapping the right arm up with my left and doing bad things to the face with my free arm.
bouncing, i got a lot of milage by standing there looking good while the (much) larger members of my team got behind the guy.
