Frederiksberg Variation[edit | edit source]

4...f5[edit | edit source]

Black 'sacrifices' the f5 pawn, although it can't actually be taken, because of 5...Nd4. White's queen is stuck in the center and is a target for Black's knight's, bishop's and pawn's. Black can sometimes play f4, with the idea of Bg4 trapping the queen.

White will have to play very carefully to not end up dead lost.
