I agree, the masse shot was the most difficult to execute of the three.
IMO, the masse was the easiest of the shots. The object ball was near the rail and only a couple of inches from the pocket. All he had to do was hit the rail in front of the ball and the spin from the cue ball would carry it in the pocket.
If he had did a masse to an object ball in the middle of the table and made it in the hole it may have been a little more impressive to me.
Maybe you haven't seen shots like this done many times. I've played pool for more than 50 years and can't count the number of times I've seen them done.
I'm not saying he didn't shoot well...I'm just saying it takes a bit more than that to make me all excited.
