Chess960 puzzles: SP weak spot

Every starting position has its own "f7" — a square next to the king that only the king itself defends. In Chess960 this weak spot is different every game: find the pawns around the enemy king and check who actually guards them. If the answer is "only the king," aim a bishop, knight or queen at that point. The mistake is watching f7 out of habit when the enemy king sits on b8 and its weakness lies somewhere else entirely.
