Poisoned Pawn
In the Sicilian Defense, the White QNP is considered poisonous — yet Bobby Fischer takes the pawn when playing the Black pieces, and permits the pawn to be taken when he has the White pieces. So how poisonous can the pawn be?
But in general it is not wise to take the pawn on QN7 for either White or Black if it involves great loss of time. And when you lose a piece on top of it, it certainly is not good.
