NEW UPDATED OPENING LINE

[July 14, 2018] Updated Opening Line by Bojan Vučković:
Pirc Defense with 4. Be3, incl. Sveshnikov-Jansa & 150 Attack

[Line 298 : 1. e4 d6 2. d4 Nf6 3. Nc3 g6 4. Be3]

The so-called 150 Attack starts with 4. Be3 where White has a pretty straightforward plan in Qd2, f2-f3 and O-O-O. After Black plays Bg7, trading the dark-coloured bishops with Bh6 and launching  a kingside attack is White’s next logical step. Black usually opposes his opponent’s plan by postponing Bg7 and advancing on the queenside instead, where c7-c6 and b7-b5 are his typical moves.

After the most common 4… c6 5. Qd2 b5 White either sticks to the above mentioned aggressive plan, like in 6. f3 Bg7 7. g4, or shifts to a more positional option, such as 6. Bd3 Nbd7 7. Nf3 Bg7 8. h3 O-O 9. O-O. It is generally easier to play the arising positions as White, but Black nevertheless has sufficient resources to get even chances.

Sveshnikov-Jansa Attack (4… c6 5. h3) is another popular setup for White. Move 5… b5 is a dubious one against this plan, since after 6. e5 White gets a very strong initiative. Black usually opts for 5… Bg7 instead, where White has a choice between 6. Qd2 (which is similar to the 5. Qd2 line), and some more sharp alternatives, such as 6. f4 and 6. g4.
