Two days ago, I played, a game as Black and after the analysis I was quite surprised to see that the computer suggested, in several moves throughtout the game, the move d5. In this position I think Black should develop first with g6 (what I played) and solve the situation in the center later.
I think the justification for this move is that it dismantles White center but I am not sure why it should not wait until later in the game.
As Black, I always try to keep a pawn on e5 (in this case) on c5. Can someone confirm this and explain me the Pirc Defense idea behind this?
Thanks in advance.
