You can clearly see Earl locking in on the 10 ball. He squares up on it 4 times; you can see him looking line in and out, 100% obvious shot.
Before he shoots he points/steers his cue at his left corner pocket, you can see his eyes looking the 10 ball in, it sounds like he calls the 2 ball, while he is clearly playing the 10 ball, and this has been done by every player on the planet.
Earl had to hit the 10 ball with speed to get it to the pocket. As most know, especially in straight pool or any game, when striking a back cut with speed, the object ball is crawling to the pocket compared to cue ball speed, while the cue ball is playing ping pong.
Your biggest concern is crashing into balls that will kiss your object ball off line, a very common thing to happen, especially with that many balls on the table. Many great shots and runs have been killed by a kiss; although Earl hit it so clean the 10 had a little pace
Anybody in their right mind or wacked out mind would not be playing the 2 ball carom at 300 mph if they were going to play it. The 2 doesn’t even look possible from the one angle I saw, nothing looked appetizing except the 10.
Here is tip I learned from Steve Miz. When the balls are in the stack and your opponent is looking for a dead shot, be ready to ask what ball they are playing; ask before they get down on the shot. Players will mumble and get down real quick and shoot. If their intended ball doesn’t go in and another ball does they say they called it.
Shaw clearly knew Earl was playing the 10 ball, he was foaming at the mouth waiting to pounce on Earl's vocal mistake, and he jumped out of the chair so fast he left his brain there.
I would be embarrassed to win because Earl made a vocal error, rules or no rules, it was obvious and Shaw knew it.
