Hamppe-Meitner Variation

The Hamppe-Meitner Variation meets the Anderssen Defense, 2...Bc5, with 3. Na4, which chases the bishop but puts the knight on the rim and loosens control of f2. The most frequent reply is the retreat 3...Bb6, while the engine's top choice is 3...Bxf2+. After 4. Kxf2 Qh4+ 5. Ke3 Qf4+ 6. Kd3 d5, the line of the Immortal Draw between Hamppe and Meitner, the play turns chaotic and is usually judged to favor Black. The engine nonetheless rates the starting position as balanced.
