He knew the rule. 100%.Crazy he lost that game because he didn't know they changed the knocking balls off the table rule
He was dead to rights the way the balls were laying so he pretended that he didn’t. Rewatch it…he tries to figure out how to follow the ball in and finally says to hell with it.
It gave him an excuse to lose. Henney got beat that game from an impossible layout. At one point EVERY SINGLE ball was on his side and somehow Tony found a way.
He knew the rule.
