One I got second hand from the house pro at my local pool hall, so I cannot guarantee the accuracy of this. We were discussing slow players and he recounted that he was watching the finals of a pro tournament in LA between Efren Reyes and an opponent who's name he could not remember.
The Opponent is hill-hill with Efren in the finals, it is 1am. The tournament is running late and everyone wants the match over so they can pack up and go. The opponent is playing slower and slower, and in the final rack gets down to the 8, which is about 1 diamond across from the side pocket. 9 is near the foot spot with the cue call center table. Opponent has 2 obvious shots, a cross-side bank on the 8 at stop-shot speed for an easy corner shot on the 9, or a simple cut of the 8 into the side with a little right-hand english for a 3-rail path around the 9 for position into the other corner.
Opponent studies the shot for an agonizing 10 minutes, then announces he is taking his permitted 15-minute break. Opponent goes for his break with Efren still sat studying his fingernails, comes back, spends another 5 minutes studying the shot, finally decides on the cut and misses it.
Efren makes the 8 and 9 and wins the tournament. As he is packing up to leave the Opponent sets up the 8, 9 and cue ball and starts explaining to his remaining friends just what was so hard about the shot and all the options he was considering. As Efren is walking out he taps Opponent on his shoulder, asks him if he can borrow his cue for a minute, takes his cue, bends down, looks at the shot it for 1 second, makes the cut on the 8 and sends the cue ball 3 rails for perfect position on the 9 in the corner. Efren says "Thanks", hands him back his cue and leaves.
