Nimzo-Indian Pin Chess Puzzles
The Nimzo-Indian Pin is a classic opening motif from the Nimzo-Indian Defense, usually after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4, when Black pins the knight on c3 to the king or queen behind it. The defining feature is the bishop on b4 creating pressure on c3, often influencing White’s ability to support the e4 push and maintain central control.
You should look for this pin whenever White develops Nc3 before resolving the tension in the center, especially if Black can immediately place a bishop on b4. Use it to provoke weaknesses, such as doubled c-pawns after Bxc3+, or to restrict White’s central expansion by making the knight on c3 tactically vulnerable. The motif is strongest when the pin is backed by pressure on e4 or when White’s king is still in the center.
