Strategic character
Positional and patient. White often sacrifices the c4 pawn temporarily for lasting pressure, and many games are decided by long-term positional bind rather than by tactics. Black's main question is whether to hold the pawn or return it for development.
Who should play it
Positional players comfortable playing with compensation rather than material, and willing to grind out long games.
