I had an idea of creating a thread where we could share cool chess problems/positions that could be used as a form of entertainment when surrounded by people less apt at chess. This old coach I know back in Lithuania knew plenty of such positions with some story behind them, and yet I can only remember one right now, I hope maybe you will remind me of some others. This one is named "The retreat of Napoleon I from Moscow". I will not state a solution just yet even though it is not hard.
The Black King is obviously Napoleon. White knights symbolize the Russian soldiers who were chasing him. The h1-a8 diagonal symbolizes the river in Moscow which Napoleon had to cross to try to escape. There are two solutions to this (one mate in 14, and one mate in 6), as if you know history, Napoleon could have been "mated" earlier yet the Russians didn't do it. Go go go!
