Vlastimil Jansa (White) Puzzle: Mate — Tactics
A mating attack often succeeds because one defensive piece is doing too much. Here, White’s active queen and bishop can target the exposed black king, while Black’s defenders are tied to vital squares around it. The key tactical idea is capturing or deflecting the defender that prevents the attack from becoming decisive. Although White is ahead in material, king safety matters more than counting pieces when forcing threats against an exposed king are available.
