Key ideas of Against the Nimzo-Indian and Queen's Indian
In the Nimzo the queen on c2 guards c3. White can take back with the queen and keep a healthy pawn structure.
Ask the b4 bishop with the a-pawn. If Black takes on c3, White keeps the bishop pair.
Fight for e4. A pawn on f3 or e4 takes the best square away from Black's knight and bishop.
Against the Queen's Indian, meet the bishop on a6 with b3. Then put your own bishop on g2.
With the a-pawn on a3, the b4 check is gone. Then White builds a big centre with e4.
Variations you learn

4.e3: the Rubinstein Variation – 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. e3 O-O 5. Bd3 d5 …. White develops calmly with e3, the bishop on d3 and the knight on f3. After the trades in the centre White gets an isolated d-pawn with active pieces.
Queen's Indian: 4.g3 Ba6 5.b3 – 1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. g3 Ba6 5. b3 Bb4+ …. Black's bishop goes to a6 to attack c4. White guards it with b3, puts the bishop on g2 and trades knights on d7. Then White grabs the centre with e4.

Traps
Greedy queen: 7...Qxd4? – In the 4...d5 line Black's bishop on b4 is attacked by the c3 pawn. Grabbing the d4 pawn with the queen fails. White checks on a4, takes the bishop, and the queen on d4 is lost.
Watch out: 8.f3? Qh4+ – After 6...Ne4 7.Qc2 f5, chasing the knight with the f-pawn is a big mistake. The queen checks on h4, the knight takes on g3, and the h1 rook is lost.
