I don't know about any 640 ball run, never heard that story before. I do know that he was a great player that lived in Cleveland and mostly gave lessons and stuff like that. I never heard much about him gambling, but that may be because no one wanted to gamble with him. I doubt he would have come to Dayton to play George Rood though. Rood challenged the Ohio State 14.1 champion Buddy Wallace, who was also from Cleveland, to play for $5,000 after Wallace bragged about playing anyone in Ohio. Wallace stayed quiet after that.
Now Chuck Morgan, he was the real deal, probably the top money player in Ohio back then (60's and 70's). All I ever heard about was him beating one guy after another. He didn't show his face at the Dayton tournaments because he didn't want everyone to know what he looked like. There was no reason for him to play George Rood. It would have killed his action either way. I don't think they ever played and they both knew about each other. I know George would have played him though. He wasn't afraid to play anyone! Mike Gulyassy knew all these guys and grew up around them. Mike turned out to be a jam up player as well and good cuemaker too.
