"When?"
Probably while Dooku was training GG. Also, we can see that in CW cartoons.
"Yeah, cause he was on a Republic Gunship, there was nowhere to dodge to, the only way to dodge it would have been to jump out of the gunship, and then Mace could have gotten him as he was falling through the air."
Even if GG has somewhere to dogde, I don't think he can dodge Mace's crush.
"Maybe, that's debatable. Overall, no, but Force Powers is debatable."
That's why I said Vaderis "probably" stronger than Mace. Vader is probably stronger than Dooku in the force, who is probably stronger than Mace in the force. And Vader is 80% of ROTS Sidious. So, Vader has 99% of chance stronger than Mace in the force😆
