Anyone ever heard about Jimmy "Jimmy" Cha??

I wonder any of you have heard about Jimmy "Jimmy" Cha.
Here's some data about him:

In Korea, he is regarded as a Legend of Poker.
Some people said that he was one of the Top 3 poker player along with Doyle Brunson, and Chip Reese in 80s;I thought maybe Johnny Chan, instead of Jimmy Cha(quite analogous!), was the one of the Top 3 player.
But when I present these data above, some people defend him with the reason that there are only few data available about 80s and since he was the ring game pro, like Ted Forest or Ming, there can't be many data about him.
I know he's a good player, but 'NOT THAT' good one.
I wonder any of you know quite exactly about him.
I really want to know exactly 'HOW GOOD' he was.
