A Symmetrical English line in which Black meets 4. g3 with 4...e6, skipping the mirrored fianchetto to prepare ...d5 and challenge the center directly.
Train it in TheoriaAbout the Keres-Parma System
The Keres-Parma System arises when Black answers 4. g3 in the Four Knights Symmetrical English with 4...e6 rather than copying White's kingside fianchetto. The pawn move supports an early ...d5, aiming to contest the d5-square that White's coming Bg2 is meant to pressure. Almost every game continues 5. Bg2, with 5. d4 a rare alternative. The engine regards the position as roughly balanced, though White scores somewhat better in practice.
