Petrov (Russian) Defense

The road to the tabiya
Step through the move order. Amber moves carry an idea — read them, don't memorise them.
Why this matters
Symmetry with a sting: counterattack e4 instead of defending e5, and reach a solid, active middlegame where White's extra tempo means little.
The structure: Petrov centre with doubled c-pawns
White: d4, c4, c3 (doubled). Black: d5. Whoever resolves the c4/d5 tension better wins the middlegame: Black targets c4 with ...Na5/...Be6, White uses the half-open b-file and bishops.
Trades: yes and no
Trade White's active bishops (especially the light-squared one) — the doubled pawns then matter. Queen trades are usually fine for Black here. Don't trade your f5 bishop for a knight — it's the piece keeping White's kingside quiet. Avoid ...dxc4 if it just activates White's bishop on c4.
Motifs to watch
- ...Na5 and ...Be6 hitting c4 twice
- ...Bf6 pressuring d4 with the rook on e8
- White's Qb3 hitting b7 and d5 — keep ...Rb8 or ...Na5 available
- White's cxd5 Qxd5 then Bf4/Bd3 — centralise your queen but keep it safe from Bc4 tempo
