Don't have to be a genius to understand what it means...
Anyways, I'm pretty sure people have explained how to counter a suplex but it might be easier to PREVENT someone from suplexing you. I guess the mod was aikido.tbm, since knowing you, I would say, you have enough skill to land yourself from a suplex in ABD or whatever. In aikido, it's is basically impossible to counter it because of the dojo size unless you're fighting someone... who hasn't planned to do a suplex but it just happened lol. Anyways, it comes back to aikido rules - keep low, don't jump too high, etc. Get your balance right, that's the main point
