[June 07, 2018] Updated Opening Line by Bojan Vučković:
Czech Pirc Defense, Anti-Philidor & Lion’s Jaw

[Line 294 : 1. e4 d6 2. d4 Nf6]

Lion’s Jaw (3. f3) is one of the decent ways to avoid the Philidor Defense as White. The main reaction from Black is 3… e5 followed by 4. d5 Be7. The ensuing positions resemble the Saemisch Variation of the King’s Indian Defense, with the important difference that the dark-squared Bishop is placed here on e7, and not on g7. White has, in view of his spatial advantage, a generally more pleasant position, but Black is not without counterplay.

After 3. Nc3 two most common choices for the players of Black are Philidor Defense (3… e5) and Pirc Defense (3… g6), covered in or Lines 295-300.

Czech Pirc Defense (3. Nc3 c6) allows White to gain a strong pawn center with 4. f4, where Black’s main plan is 4… Qa5, followed by e7-e5. White has two paths to obtain a small, but pleasant advantage: 5. Bd3 and 5. e5.

If Black wants to enter the Philidor Defense via another move order, i. e. 3. Nc3 Nbd7 with the idea e7-e5, White has at his disposal a promising alternative to 4. Nf3 in 4. f4.

[Diagram: White to Move] Black is ready to play Nc4, and White has to find how to stop his opponent’s plan. What is the best solution for him?
