[December 01, 2017] Updated Opening Line by GM Bojan Vučković:
Sicilian Defense, Old Sicilian – Kalashnikov Variation (incl. La Bourdonnais Variation)

[Line 429 : 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 e5]

Apart from the Kalashnikov Variation, Line 429 covers some rare lines such as the La Bourdonnais Variation – 5. Nb5 a6, where White should have several pretty straightforward paths to reasonable advantage.

After 5. Nb5 d6 White can choose between the positional 6. c4, which typically leads to slightly more pleasant positions for White, or the more ambitious 6. N1c3, where besides a transposition to the Lasker Variation after 6… Nf6 (Line 434), Black can continue with 6… a6 7. Na3 and than choose one of the two popular lines: 7… b5 or 7… Be7.

[Diagram: White to Move] One of the critical positions in the 7… Be7 variation, where White is facing a choice to either capture the bishop on g3, or refrain from doing so. Which of the two should be preferred?
