Prague Variation

In the Prague Variation, Black meets the Rubinstein System's 6. g3 with the natural 6...Nf6. This develops a piece instead of committing to the Swedish 6...c4. White almost always continues 7. Bg2, after which 7...Be7 forms the Main Line, and 8. O-O O-O reaches the Classical Variation. The Wagner Variation, 7...Bg4, and 7...cxd4 8. Nxd4 Bc5 are the principal deviations. Practical results are close to level, and the engine rates the position as roughly balanced.
