Put yourself in the position of the black player. White has just played 1. Rg2, a move which contains an aesthetically-pleasing tactical threat. But how serious is the threat? Does black not have a concrete threat of his own to execute? Is there an outright refutation?
Black didn't play the strongest move at the board, whilst I didn't even consider it when Andrew Stone kindly sent me the position to mull over. See if you can do better, and tell us what you come up with in the comments.
