Figure[Black to move]

Again, there is nothing difficult here if you ask (a) which White pieces are loose and (b) whether there is any way you can attack them at the same time. Here both of White's rooks are unguarded (loose rooks in the corner of the board is pretty common, and make nice targets if the pawns diagonal to them—e.g., the g2 pawn in this example—have been moved). Look for a square where lines leading to both pieces intersect; see that Qe4 wins one of the rooks.
