Lion Variation, Bishop Sacrifice

The Bishop Sacrifice is White's most direct attempt against f7 after 5. Bc4 Be7. With 6. Bxf7+, White gives up the bishop for a pawn to draw the black king into the open. Black almost always replies 6...Kxf7, and 6...Kf8 is a rare alternative. Engines consider the sacrifice unsound and give Black a clear advantage. Black also scores better in practice, so the line is mainly a speculative surprise rather than a theoretical test.
