Key ideas

• Black delays ...e5/...e6 decisions while keeping ...a6 control over b5
• Asymmetry: White often gets space and attacking chances; Black gets counterplay on the c-file and queenside
• Typical piece placement: knight on d7 or c6, bishop on e7 or g7 depending on the system

Typical plans

• White: English Attack setups with Be3, Qd2, f3, g4 or classical development with Be2/Be3
• Black: ...b5 expansion, pressure on c-file, timely ...d5 or ...e5 breaks
• Both: watch d5 and b5 squares — heatmaps of tension and control often light up there first
