Learn How to Win a Pin: Tarrasch Defense Theory
This middlegame puzzle comes from the Tarrasch Defense, where piece activity and tactical accuracy matter more than raw material count. White’s setup shows a classic pin-based idea: a bishop on the long diagonal can pressure a key defender and create a short forcing sequence. In classical chess, these positions often reward active bishops, awkward queen placement, and the ability to exploit loose pieces before the opponent can coordinate.
