Nimzo Indian Defense Kingside Attack Beginner Chess Puzzles

In the Nimzo-Indian Defense, White often meets 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4, and a kingside attack beginner theme appears when White uses the center and pieces to attack Black's castled king. The idea is usually not a direct mate, but a simple attacking setup with moves like e4, Nf3, Bd3, and h4-h5 to build pressure on the kingside.
