Learn How to Spot Mate in 2: Bishop Sacrifice
This classical chess puzzle comes from the Accelerated London System and shows how a well-timed bishop sacrifice can force a mating net against an exposed king. The key idea is that the attacking side uses piece activity, king safety, and a vulnerable pawn shield to create a direct threat that cannot be ignored. Even when material is equal, a single forcing move can collapse the defender’s position if the king has too few safe squares and the back line is overloaded.
