Catalan Main Line: 7.Qc2 b5! – Comprehensive Black Repertoire

This PGN file provides an in-depth analysis of a sharp and ambitious Black system in the Catalan Opening, focusing on the bold 7…b5! pawn thrust. After the standard opening moves 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.g3 Be7 5.Bg2 O-O 6.O-O dxc4 7.Qc2, Black immediately challenges White’s setup with the aggressive 7…b5, leading to complex, double-edged positions.

The file contains extensive coverage of multiple variations and lines, providing a comprehensive roadmap for Black across White’s various tries.

Critical Position After 8.a4 b4

Following 8.a4 b4, White faces an important decision at move 9. The file covers four main options:

9.Nfd2 (Main Theoretical Line)

The most flexible and popular continuation at the highest level. After 9…Nd5 10.Nxc4 c5, Black achieves excellent counterplay. The file explores multiple branches including:

• 11.dxc5 Ba6 – Black develops actively with light-square pressure
• 11.e4 Nb6! – A key tactical resource
• Various other White tries, all met with concrete Black responses

9.Nbd2 (Solid Alternative)

Another natural developing move. Black continues with 9…Nd5 or 9…b3, maintaining flexibility and fighting for active piece play.

9.Qxc4 (Direct Sideline)

White immediately recaptures the pawn. After 9…Ba6 10.Qc2 Nbd7, Black gets comfortable development with pressure on White’s position and good piece coordination.

9.Ne5 (Sharp Sideline)

The most forcing continuation. After 9…Qxd4 10.Bxa8 Qxe5 11.Bf4 Qh5!, the file shows multiple variations demonstrating Black’s compensation for the exchange with active pieces and threats.

The file is structured with multiple variations and sub-lines rather than deep single-line analysis, giving Black a complete repertoire covering all of White’s realistic options in this dynamic system.
