#### QUESTION

The opening showed here is quite common. Is it generally a good or a bad idea to give up a Knight and a Bishop for the King-side castled Rook and the f-pawn? In terms of their "standard" value, both pairs are generally considered as being worth 6 points.

[FEN "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1"]

1.e4 e5 2.Nf3 Nf6 3.Bc4 Bc5 4.Ng5 O-O 5.Nxf7 Rxf7 6.Bxf7+ Kxf7



This whole sequence is bad for white. The minor pieces are stronger at such an early stage of the game. White has virtually no development, while black now has more development and tempo. Almost any player should value 2 pieces over 1 rook. Just continue developing instead of the overly optimistic Ng5.
This may be acceptable in the dilworth attack or Open Ruy Lopez where black sacrifices 2 pieces for a rook on f2
