Ages ago, I watched the original world championship on TV and was thinking how can anybody solve the whole cube in 19 seconds? I figured there must be a completely different method to it. Now I know it was Fridrich, but at the time I imagined it was something like this:
Take a solved cube and make five random twists. To solve that cube, you recognize the patterns inherent in that cube, and make 5 twists. Solved.
The imaginary method is to take a fully scrambled cube, and build up blocks, groups etc such that when you have enough stuff aligned you can make 5 or 6 twists (maybe insert an algorithm in the middle) and you're done.
In other words, you make 40 or so turns to condition the cube nicely, without completely solving any layers or faces or piece types. Then you make a few moves that solves everything at once.
Does this exist? Is it practical?
