Ender's Game Chapters 6-8

In the next two chapters of Ender's Game, Ender is just starting to get the hang of Battle School. I think one very interesting thing we learn in these chapters is that Ender is only going through Battle School so that buggers won't kill Valentine. This shows how much Ender cares about Valentine and that he doesn't really want to be at Battle School. In this chapter, Ender shows his tactical genius side once again, by outsmarting just about every army commander. We also meet Bonzo in this chapter. The interactions between Bonzo and Ender are another thing that fascinated me. Bonzo seems to be a very incompetent leader and Ender knows it. When Ender stands up to Bonzo about letting Ender practice with the other Launchies, Ender shows an unmatched confidence. What I didn't understand is that Ender was respectful of Bonzo's leadership and pretended that he had lost the argument,     so that he did not weaken Bonzo's control of the Salamander Army. Ender did this even though he did not think Bonzo was a good commander, at all. I guess this might be part of Valentine coming out in Ender.
