| Catalan, Open, Classical line |
In chess, E05 is the ECO code for the Catalan, Open, Classical line chess opening. The game begins 1.d4 Nf6 2.c4 e6 3.g3 d5 4.Bg2 dxc4 5.Nf3 Be7. White trades the pawn for a lead in development. Without the d5 pawn, White's kingside bishop stymies Black's queenside development. The Open Catalan line here has been a favorite of Anatoly Karpov and Efim Geller as Black and Oleg Romanishin has done very well with the White pieces.
