In Parr-Wheatcroft 1938, http://www.chessgames.com/perl/chessgame?gid=1284171, since White wins, 21 Nxe6 is the definitional brilliancy because of leaving Rook in jeopardy. [Error corrected last two comments this thread with actual outcome 1-0 and finding Black's reversal of outcome the object. All the references are now correct to this score, and Black's winning move as to be improved should alter one of those 21, 22, or 23 actually made.]
