Slav Defense: Chebanenko Variation
Main Line
1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 a6
Overview
A modern Slav Defense system — 4...a6 prepares ...b5 to expand on the queenside while keeping all standard Slav structural ideas available. Named after Moldovan-Soviet trainer Vyacheslav Chebanenko (1942–1997) who developed the line in the 1980s. After 5.c5 (locking the queenside) or 5.a4 (preventing ...b5), Black has multiple setups depending on White's reply. Now considered one of the most reliable Slav systems — used by Vishy Anand, Levon Aronian, and Shakhriyar Mamedyarov as a regular Black weapon.
