Answers.Body: <p>Playing ...d5 isn't your typical Pirc idea, although it can be played under the right circumstances. In the diagram, White's d3-bishop and f3-knight are vulnerable to a potential ...e4 push. In addition, your g4-bishop provides some tactical possibilities by pinning the knight. Concretely speaking, everything just works nicely for an immediate challenge in the centre. It's not so much that ...d5 is a "Pirc move", but rather that it just works well in this particular position.</p>
  
  <p>You are correct that normally you wouldn't play like this so early on in the Pirc, but one must always adapt if the position calls for it (in any opening). Also, with the bishop on g4 you won't really be able to get a satisfactory Pirc position by playing normally anyway. In both the Pirc and King's Indian type structures, it's very important for Black to retain his light-squared bishop (in order to fight for the weakened light-squared complex). If White is given control over the light squares so early on, you'll be facing an upward struggle.</p>

  In most early-stage Pircs, black is slightly worse, so of course, the computer will prefer any move that equalizes, or in this case, gives you a slight advantage.
  White is not well-placed in the center due to the pin on the Nf3, and the Bd3 interferes with the Qd1's protection of the center (d4) too. Black can effectively "blow-up" the center here, which leaves him at least equal.
  It comes down to specific tactics here, and d5 works. If you wait, white may play d5, and your opportunity would be lost.
  One more note: I do not play e4, so I don't think about this much, but in many e4 openings, black wants to get in the equalizing d5, thus you don't usually see the bishop on d3 since it makes d5 easier to achieve. It is usually on e2, c4, or b5, so Bd3 was probably not best. In d4 openings, which I play, Bd3 is common, but black already has d5 in, so it is fine.
