If you want to learn more, watch Day9, that helps a ton. Watch replays from GSL, TSL or whatever. There are a lot of good players that stream their plays such as LiquidTLO, EGHuK, Destiny, etc etc.

And is it just me or Malaysians really love Combat-EX? Now I've seen his play and to be totally honest, he is a decent cheeser, which obviously doesn't really represent much especially if you don't have a follow up after the cheese. What I said is a theory as I just finished watching a game of spanishiwa vs combat-ex and it was horrible to even watch it. Worst of all he trash-talks in the game. Yet however, if you like his style of play, watch KiwiKaki instead. He cheeses as well, except he has a follow up and his cheese is rather a boost for him in the late game rather than an all in.
