• American teenager NM Jacorey Bynum, rated below 2200, checkmated world No 1 Magnus Carlsen in Chess.com's Titled Tuesday online Blitz tournament.
• Carlsen, a five-time world champion and widely regarded as one of the greatest, rarely loses, especially by checkmate, to lower-rated players.
• Bynum, 19, surprised Carlsen with a queen sacrifice (35. Qxh5+) that led to the checkmate, earning applause from the chess icon.
• Carlsen's blunder of moving his bishop to d4 instead of blocking the queen's path created the opportunity for Bynum's rook to deliver the checkmate.
