Re: Aikido does not work at all in a fight.
Being with Tomiki Aikido for my entire 56 years, I can tell you we fight on the mat also. We do use shime waza (chokes), kansetsu waza (arm bars), kaeshi waza (counters), ne waza (mat pins and holds). We do chokes with just our legs---Sankaku jime for one. We also do combinations of chokes and armbars etc. I don't know who told you we don't fight on the mat but whoever that "smart" person is, you should tell him he'd better research is material.
