Honestly, that move works only against beginners and bad players.
If you only use that move and don't improve you'll always be that fag who can't beat actually experienced people and you'll not be happy when you reach blackbelt and can't play on the newb servers any longer.
If you want a simple move that forces you to improvise: just contract pecs and then do whatever is necessary to win. Some fags may call you a shoveller, but hey, even some of the best players use that move, so whatever.
