Here is a position I reached in a live game today. The puzzle is very easy, at least the first move is very easy to find, but the variations make it interesting. White can force a win of at least six points of material in a number of different ways. EDIT: "Set Begin" and "Set Focus" don't seem to work. Just click "Solution" on the puzzle and go to the move 14. ... Nd8?? On the movelist. The rest of the game is nothing special.

Black's inferior option (Mate in three):

Seconded! Very cool!

For anybody very perceptive, I made a mistake with 10. Bc3?. What should black have done?

Thirded very very cool. I gotta say I really liked your notation and working through the other options as well.
