The combination begins with 15.Bxh7+, dragging the king away from its shelter. After 16.Qxh5+ Kg8, Lasker gives the second bishop with 17.Bxg7, stripping the remaining pawns and exposing dark squares around the king.
The point is not an immediate mate. Rf3–h3 brings a rook into the attack, and 20...Qh6 permits Rxh6+. Lasker then recovers material while maintaining checks, eventually reaching a winning queen ending.
Study this game as a coordination lesson rather than a slogan to sacrifice both bishops. The bishops remove the pawn cover only because queen and rook can enter with tempo; without those follow-up routes, the same sacrifices would fail.
