Fianchetto

Fianchetto - Black Bishop has moved up one row

Fianchetto is this week's most annoying word. I came across it in The Queen's Gambit but I failed to take note of the page number and Google Books won't tell me, so if you care you'll have to dig it out yourself. 

Fianchetto is an Italian word, it is the diminutive of fianco (“flank”). It just means that a bishop has advanced to the second row, which implies it now has a much wider range of attack. In the board position shown above, the fianchettoed black bishop now has the white knight in range. Taking the knight would also put the white king (the piece with the cross on top) in check. However, if black takes the knight it would subject to being taken by the pawn on B2.
