  Benzol: The last move is a lovely deflection sacrifice. Is 5.Qe2 really a bad continuation in this variation?

  perfidious: <Paul>: My recollection is that, in the early seminal work on the Pirc by <ray keene> and Botterill, their comment at the conclusion was that in future, 5.Qe2 would probably rarely be encountered.

In my days facing the Byrne system, never had anyone play 5.Qe2 against me, which was a pity-the move looks awkward and is not the first idea which would enter my head if I were White.

May-20-13  Abdel Irada: White's plan of development with 5. Qe2 also strikes me as artificial, although perhaps just playable.

After 7. O-O-O, however, I think White is already much worse. Black is far better placed for a castle-on-opposite-wings pawnstorm race, so it would seem wisest to avoid it. Perhaps, if he wishes to be consistent, 7. e5 would be in order, when Black doesn't yet have the counterpunch ...b4. However, I still have little faith in White's position.

  perfidious: <Abdel Irada>: Believe the move that received ? in Keene/Botterill was 8.e5, along with the note '(c)onsistent but bad....', though it has been so long that I don't totally trust my memory as I once did.

Black's fourth move, recommended by the above-named authors, always struck me as more flexible than playing the committal 4....h6 or much more popular 4....Bg7, especially as the latter often loses a tempo (or commits to castling) when White plays a quick Qd2 and Bh6, with positions which also be reached from the move order used in the 150 Attack.

  Benzol: <perfidious> Alan I must have a good look at my copy of the Pirc Defence. As <Abdel> says 5.Qe2 looks artificial but this game makes it looked like a forced loss. Thankyou both for your input.
