= Sicilian Defence, Poisoned Pawn Variation = The famous Poisoned Pawn Variation. Black accepts the pawn. This line after good results from Black, initially Fischer but later Kasparov has seen a decline in popularity of 6.Bg5.

The line was popularized by Bobby Fischer, who in playing this line said that he could grab a pawn, give his opponent three or four moves in development, and still win! Today the line is just as messy as it was in its heyday in the 1970s, but is now considered to be equal with best play. Today there have been lines analyzed up to twenty or thirty moves in depth, such as this one, the main one.
