Train it in TheoriaAbout the Two Knights Defense
The Two Knights Defense is Black's 6...Nbd7 in the Harrwitz Attack. It develops the queen's knight to d7 rather than committing a pawn with 6...c5, 6...c6 or 6...b6. White most often replies 7. Bd3. The engine prefers 7. c5, the Blockade Line, which gains queenside space and rules out ...c5, while 7. cxd5 clarifies the center. White scores well after both 7. c5 and 7. cxd5, and the engine rates the position as roughly balanced.
