This is a well-known opening mistake by black, letting white sacrifice the knight on e5 and get either a rook or a very strong attack in exchange for it. However, after 6. Qxh8, there doesn't seem to be a lot of analysis. Black has various possibilities of trapping the queen on h8, starting with 6. ... Nf6.

In the diagram I gave 2 lines in which black doesn't manage to trap the queen. These involve the king walk to g6, though. I'm interested in other lines you might have to give white a difficult time saving his queen.

thanks for sharing
