An Interesting Combination

The other night at the Marshall Chess Club Asa Hoffmann presented me with the following position from a game of his with Ed Frumkin. Contained in the position is an interesting combination- two moves with the same idea win.

It’s black to move:

Black wins with either f5+, e.p. h5+ or vice versa h5+, e.p. f5+ when Rxc1 and the a knight fork or bishop skewer will decide. I love the symmetry in this position- it’s rare that just combinatorial symmetry occurs over the board.
