Black from invading on e4 and avoiding any ...Nh5 ideas. Furthermore, White is

similar variations, which all seemed to contain a consistent theme. When White
plays 5 c5, he is intercepting Black's plan of challenging with ...b5. It is a
space-gaining advance, but although White seemingly grasps the b6-square,
making Black's ...a6 look pointless, there is always a danger involved in
relieving tension in the centre so soon. Indeed, Black can try to break free
with either ...b6 or, better still, ...e5, but the question is: can he
satisfactorily arrange such a break? I have basically concluded that the
significant shift towards 5...Nbd7 suggests that Black cannot satisfactorily
arrange ...e5 or ...b6, and I believe the last two variations are
representative of why. If White can comfortably settle his bishop on the h2-b8
diagonal, then Black will struggle to get enough pieces covering the e5-square
to arrange the ...e5 break. Furthermore, although ...b6 is more attainable,
leaving aside the weakening repercussions that this might have on Black's
queenside pawn structure, seeing how Black's rook is deprived of access to the
b8-square, opening the b-file might not be that desirable either.} (9. Bd3 Ne8
