Two shots..
First, playing barbox 8-ball before I really knew how to play the game.. My last ball in the middle of the top rail, 5 feet away, with cue ball also in the middle of the table. I had figured out a while back that a bank with the particular layout back to the corner pocket on this particular table, was a scratch two rails in the corner if I played it with running top english. Opponent had the 8 ball in one corner, his last ball in the other. I saw a possibility to bank my ball back into his, pocketing it, with my ball staying right there to be made when the cue ball came two rails. Called it, shot it, and the only thing that kept me from making it, was the banked ball rolled off an inch or two, cutting his ball in slightly, instead of making it straight in and stopping there. Cue ball came around and got in behind my ball, frozen to it and the rail, leaving an impossible kick for him. Won that game from absolutely nowhere. In hindsight, the four-railer is the shot, but good luck getting that to go on a crappy bartable..
Second, I was up to $60.00 a game (~1996) playing a guy from Chicago some last-pocket 8 ball. I was playing real well, and he started slow-rolling the cue ball into the head ball of the rack to slow me down. He popped one makeable shot off the rack from the corner ball, and it ended up almost dead straight in to the corner, with the rest of the rack nearly frozen together. No other makeable ball on the table, even with ball in hand.
I had just bought "Winning One Pocket", and "Shots, Moves, and Strategies" because this same guy had been woofing at me to play One Pocket. In one of the books was a shot that Bucktooth had played on somebody in a game of One Pocket, where it laid almost exactly the same, and he jumped the cue ball onto a ball he could see straight in, and made the ball, hopping the cue ball about two feet up in the air, and about 5-6 inches sideways. I figured what have I got to lose?, and gave the shot a try, having never played anything remotely like it.
Executed it perfectly, the cue ball burrowed into the stack, and pushed a few balls out. I had exactly one shot, in the side, and ground out the run, nudging a ball out here, secondary break there. Got AWLLLLLLL the way out for the cash, and needless to say... He quit me after that game. :-D
