While we don't teach speed/freestyle games, you can find some strategies in the Strategy forum. Just go to Advanced search and search through the
Strategy forum. That goes for anything not covered in our training materials. The SoC was created to help players learn the basics, and we only teach what we're 100% comfortable with teaching.
I'm no expert on either setting. When I have to play freestyle, I normally approach it as a Sequential game, but there are specific approaches you can take with Freestyle games that don't apply to Sequential.
I do like Speed Escalating games, although I haven't played many. The only difference between a Speed game and a Standard game is that you only have 5 minutes to make your move, so I find I use Auto-Attack a lot more, and I have to settle for quick and dirty calculations.
As far as Speed Terminator/Standard Escalating games on basic maps, though, if you follow the First Four Moves, you'll do fine.
