Impossible Sparring Challenge

I'm pretty sure the only one that has counted for me was the von flue or reversal von flue, and I stupidly retried the challenge at the end because I thought I wasted like 60% of the session with going back forth in the positions looking for one. I haven't been able to get the progress since as it relies heavily on the cpu to make the moves necessary in order to execute it. Most of the time the cpu sparring partner will just sit there in full guard and waste your time limit for the session.
