The Long Diagonal In the Queen's Indian Defense
If I took anything away from the QID book I have, it's that the response for white with g3 after b6 is most crucial. Playing against the long diagonal as white gives them the best odds to combat the QID. Many tactics can arise for white, as usually the Bb7 is undefended whereas White's is usually guarded by the King after castling. Here is a Friday night G30 I played as white to illustrate this point.
