I've read that book too. It's a good read I would say. I like how most of what he says can be used in competitive smash.
I started playing melee again a few days ago, practicing for Evo and such. Besides getting my feel of chain grabs and movement back, I've been trying to implement some new stuff into my game. I've realized that against higher level players, or just players with ICs experience, blizzard and u-tilt become less useful as people start to DI out before I can follow up with something like a grab. Especially u-tilt becomes less useful, as you might even get punished if they mash out fast enough, which is why I'm trying to do more u-smash and sh-uair where I would normally use u-tilt. As for blizzard: My favorite way to set up this move has always been with the "initial-dash-desync"* as you retreat while setting up rather then moving closer to the other player as you would with the normal dash-dance-desync. Anyway, I've started to to use the same trick to make Nana use Ice shot instead of blizzard while I dash dance/move around with Popo. I think it's easier to get grabs out of ice shot hits because you can't SDI out once you're hit. The timing for the desync is a little tricky, but I'm able to do it pretty much consistently by now. I'm going to test this against other players tomorrow.
*You dash twice, which causes Nana to freeze in a glide animation because she can't keep up/dash dance. This animation can be cancelled by pressing down on the control stick, which is why you can make Nana do a blizzard by pressing down-b. If timed correctly, Popo will still be in his initial-dash animation when you press down-b, and because you can't cancel an initial-dash by pressing down, Popo will not be affected by the input.
TL;DR: Works the same way as dash-dance-desync. However, I think this variation is better in some situation because you move away from your opponent while you begin the blizzard. It's like a faster back-roll-desync.
If you have no idea what I'm talking about, you should watch me play the following days. I'm going to stream some Evo practice with King Funk. I'll give a link once we playing.
Anyway, I would like to talk about crouch canceling. I've realized that this is something I'm not utilizing enough. So, to get things started, when do you go for a CC in general? Every time you throw out a move a low procent in case you miss and get punished? Do you bait people to attack you while you're CC'ing? In which match ups do you think it's important?
