After the match was done I set up the shot that he had and asked him to hit it again and make sure he didn't hit the 8. Sure enough the only two balls that moved where the stripe and solid balls, 8 ball didn't move. I then set it up again and asked him to just skim the 8 and it was then sent directly into the rail. I setup the shot a few more times and sure enough only the stripe and solid balls moved every time.
Afterwards I thought about it a little. The only way you could of gotten the 8 ball to move was if you skimmed the 4 ball so much that it would kick off of the stripe and back into the 8 ball but then the 8 ball would of headed towards the back left corner pocket and would of been the last ball to move instead of the first ball to move.
So this match taught me once again that even if you think a player has the same integrity that you do you should still have someone watch the hit. I have even seen 7s at a national tournament claim a good hit when there was no way that it was.
