To be different I'll share something my buddy did during a 9 ball tournament a couple of years ago.
7-8-9 on the table. The 9 ball was where you rack it and the cue ball was frozen to the back of it, hooking him from the 7. He couldn't make an easy kick because the 8 was blocking most of the kick lanes, about 6" from the cue ball.
In a moment of 'brilliance' he decided to shoot the 8 ball in illegally, so that it would spot up next to the 9 ball, creating a cluster his opponent would have to deal with. Unfortunately illegally balls pocketed in 9 ball don't spot up. That only applies on a push out when pocketing the 9 ball.
So his opponent grabbed the cue ball and tapped in the 7 and 9 for an easy win. I thought it was hilareous. My friend didn't find the humor at the moment but I'm sure he'll come around...
