After 1. d4 Nf6 2. c4 e5, black has a development lead. In addition, white has weakened its black squares with 2. c4, which is further intensified by the relatively frequent exchange of black square bishops. The Budapest Gambit is played relatively rarely, as White has the opportunity to gain a small but permanent advantage without risk by giving back the extra pawn. However, if White attempts to keep the pawn, he must be prepared for a sharp game.
