The only time i ever use dk's forward b is if i'm at a stage like brinstar and i'm too far away to reach the edge, i use it to stall myself until the acid/lava/whatever the hell that crap is comes up so it can hit me and get me closer to the edge. Either that or stall myself so that the barrel comes at kongo jungle 64. Other than that, i can't stand that move. All too often when i ledge tech, i accidentally do a forward b instead of an up b. I usually hate the dash attack, but i use it occasionally. I use it if i expect someone to either spot dodge, or when someone techs in that direction cuz they will get hit by my dash attack at the last second, and give me a chance to combo out of it. Its usually not a smart move to use though because its pretty laggy. Dk's u smash is horrid. Sure its pretty **** strong, but the hitbox is so small, and it only attacks directly above him. The only time i use this move is after a d air or f air that pops my oponent up. It works great against characters like fox. At certain damages, if you manage to d air a fox, you can just about fully charge your u smash and land it. Its pretty much always gonna be a ko, lol, and then you can just break into song "just make it clap" *clap clap clap clap clap clap*. I don't use the f smash unless its a guaranteed hit. Sometimes if i u throw a fox/falco/falcon, and i know that they are going to "di" off the stage, i just f smash in that direction because with a bad influence, a f smash is deadly even at low damages. All other moves i use on a regular basis. D smash is good for crouch canceling against an oponent at high damages by the way. If they're at over 100 damage, a crouch councel'd d smash is a great way to put them away
