user8374: I accidentally touched my bishop and opponent's "Knight", while reaching for my queen during a game, almost simultaneously. Am I forced to take the opponent's piece?

user7500: FIDE Article 4.3:

Except as provided in Article 4.2, if the player having the move
  touches on the chessboard, with the intention of moving or capturing: 
a. one or more of his own pieces, he must move the first piece touched
  that can be moved 
b. one or more of his opponent’s pieces, he must capture the first
  piece touched that can be captured 
c. one piece of each colour, he must capture the opponent’s piece with
  his piece or, if this is illegal, move or capture the first piece
  touched that can be moved or captured. If it is unclear whether the
  player’s own piece or his opponent’s was touched first, the player’s
  own piece shall be considered to have been touched before his
  opponent’s.

If a player touches a piece without the intention of moving or capturing (e.g. fingerslip), there is no touch move restriction.
