Tactics
Back rank weakness
Trapped by your own pawns
The idea
A king on its starting rank with the three pawns in front unmoved is in danger. If you can get a rook or queen onto that rank, the king has nowhere to escape — checkmate. The fix: push one of the pawns (h3 or g3 for White) to give the king a 'luft' (breathing room).

Black's king is trapped on the back rank by his own pawns. A single white rook reaching the 8th rank ends the game.
