What is a removal of the defender tactic in classical chess?

Removal of the defender means capturing or forcing away a piece that is protecting something important. Once that defender disappears, another tactical idea becomes available, such as winning a queen, a bishop, or a key square.

How do I know when a pinned piece is vulnerable?

A pinned piece is vulnerable when it cannot move without exposing a more valuable piece behind it. If that pinned piece is also under pressure, it may become the target of a forcing sequence that wins material.

Nimzo Indian Defense Normal Variation Puzzle (Rated 1567): Win Material — Tactical Refutation

This puzzle comes from the Nimzo-Indian Defense and shows a classic middlegame tactical refutation based on removing a defender.

In positions like this, the best move is often not a direct attack on the king, but a forcing sequence that wins material by collapsing the defensive structure. The result is a decisive advantage rather than a mating attack.
