In fact, I would call the KIA more of a system than an opening. My opponent paused here for about 10 seconds to decide what to play.} g6 {One of many replied with Nc6 being the most popular.} 3.

Black pins the f3 knight and prepares to complete his development. The problem is that White has a strong reply. O-O makes more sense here.} (7... O-O 8. Re1 e5 9. a3 b5 10. h3 a5 11. Be3 a4 12.
