Closed, Chigorin Defense, after 10. Bc2, through 13. dxc5

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3 Na5 10. Bc2 c5 11. d4 Qc7 12. Nbd2 Nc6 13. dxc5

An early pawn trade leaves the c-file as Black's avenue and the d-file as White's - both sides get real winning chances down their own file. The classic tabiya: White probes with c3/d4 and the b1-knight's journey; Black keeps the strongpoint on e5 and chooses between ...c5 counterplay and kingside defence.
