my favorite of the "how to run 100" type videos was Rempe's. He's the clearest.
Some advice from jim that I think is great -
· Never shoot a ball you can miss. Too many players shoot a tough shot for the sake preserving a pattern or sticking to their original gameplan. Just adjust. As long as you leave at least one breakball (doesn't have to be the one you originally felt was best), you're okay.
The ONLY time I might shoot a less than 100% shot is when I have a choice between shooting a missable key ball to get good on the break ball... I'd rather do that then shoot the break ball and leave myself nothing to open up the rack. And even then, you have to be honest about your odds. If you're trying tough key ball that you are only 50% or less to make, you probably should just shoot the break ball instead and do a planned safety in the next rack.
· You don't have to slam the break ball. Don't risk missing it. Just pretend the rack isn't there and shoot the break ball like a normal shot that you're trying to play 3 rail shape from. In other words you're only hitting hard enough to that the cue ball might go up to the top of the table if there were no other balls in its way. I'll second the recommendation about Grady's break shots and key balls.
· Keep away from red herring "wired" combos and caroms. If there's more than an inch of space between the balls and they're not lined up perfectly, it's a crapshoot and you probably should avoid it. Lotta points are lost when 1 greedy player splatters the rack trying to play a dead ball that wasn't really there.
· Don't be afraid to foul on purpose to get out of trouble. Just try not to do it 3 times in a row. Give the other guy a chance to screw up. Many players are allergic to intentional fouls so when you nudge the cue ball into a tough situation, they will try to safe or shoot their way out of it legally and often it will bite them in the ass.
· Don't be lazy about position, ever. Pick a spot you think the cue ball can get to, make it a very small dime-sized one, and try your hardest to plant the cue ball right on that dot.
