1. e4 d6 {This system has been developed and introduced in practice by the
Yugoslavian grandmaster V. Pirc and the Soviet master A. Ufimtsev. 
Formally it is classified as a semi-closed game judging by Black's move 1.
However, many positions arising there have a strategic similarity to the 
King's Indian defense. In the XIX century this original opening was 
frequently implemented by the known German master L. Paulsen. Nevertheless
it was considered to be a difficult opening for Black; only recently it 
has evolved into a full-fledged opening system. Real elaboration of the 
opening only started in the late 30s of the XX century and it now has 
become especially popular. How this can be explained? This opening is very
flexible; it allows the start of a complex strategic struggle where both 
sides have their chances. The Pirc - Ufimtsev defense has been implemented
by many prominent chess players: M. Botvinnik, T. Petrosian, B. Spassky, 
R. Fischer, V. Korchnoi, J. Timman, N. Short, V. Hort, L. Ljubojevic, Y.

1. e4 g6 {This is a flexible sequence of moves, which is especially 
popular in recent years. With this method of play Black can avoid some of 
the variations previously presented, for example, 4.¥g5. In this case, 
the effect of possibly advancing the white e-pawn is diminished, while 
Black's pressure on the d4-point is intensified. Later, the black king's 
knight may sometimes be developed to h6, which also gives Black wider 
opportunities. However, this set-up also has some serious drawbacks. When 
abstaining from attacking the white e4-pawn Black offers the opponent a 
broad choice of possible continuations including a possible transposition 
to the King's Indian defense which may not appeal to every black player. 
The game Krivun - Pismenny perfectly illustrates the strategic struggle in
this variation.} 2. d4 ( {Interesting is attempt of immediate flanking
