DieterVerhofstadt/Applying Dwyrin's basics

In the meantime I assume many players will know dwyrin's youtube channel. He's a high ranked amateur, probably 5-6d but only known to play online. On Fridays he plays with lower ranked accounts and explains what he's doing, while keeping it "basic". These basics are well worth repeating:

1. corners, sides, centre?
2. defend your weak groups, attack the opponent's weak groups, else take a big point (see 1)
3. play good shape, harass the opponent's bad shape
4. keep in mind the opponent's winning condition
