1. e4 d6 {"Annotating a game which opens with the so-called Pirc-Ufimtsev
Defense al­ways gives me an uncomfortable feeling. It is not the moves, it is
not the varia­tions, but it is the name of the opening that disturbs me. Who
is the originator of this defense? I have no doubt that Pirc, Ufimtsev, and
even Robatsch and others, worked a great deal on the open­ing moves, but the
idea that 1...d6 is a playable move occurred first to a Hungarian named Antal
Aladar in 1934. If you doubt this, I can show you a booklet of twenty pages,
published in 1934 with the title, “De Hat (d6) (“Hat” is the Hungarian
word for six — pro­nounced hut.)" (Laszlo Szabo, Chess Life & Review,
August 1973, p434)} 2. d4 Nf6 3. Nc3 g6 4. f4 Bg7 5. Nf3 O-O 6. Bd3 Nc6 7. e5
