13.Rxc6! [An interesting exchange sacrifice for two pawns. If White can activate his queenside pawn majority, Black won't be able to save the game.]

Chess has been a large inspiration for artists! Here is one piece by Honore Daumier in 1863 called The Chess Players. What's your favorite chess-related art piece?
