Well, for 90% of my starters, i use the noob clap. So this is usually how im beat:
Judo:
Most of the time people kick me, and aim high. If you aim your kicks around their chest, and they clap, you can hit their shoulder and hopefully break it.
Aikido:
Well..usually its being kicked, and then the kick knocks me into the air and i get shoveled/flipped over. Otherwise if the player is pretty good they flip me over.
But yea, thats how i usually get beat, hopefully it'll give you some ideas.
