Obvious winning move or unobvious brilliant quiet move?
31...Rh6 is the best move and obvious; but some will opt for QxN. White's failure to counter Rh6 leads to M3; Black missed this continuation (try 33..Qxe2+ not Qh1+; 34.Kg1 Qh2++). So I guess it is considered a brilliant move.
I played this game and there was a confusing move that Stockfish decided to identify as brilliant, even though it seemed like the most obvious move to me.
