Malcolm Pein follows a Nunn on a run today’s
We refer to Grandmaster John Nunn, of course, whose checkmating skills were featured in aof Checkmate Monday. Today we have a chess problem and one of Nunn’s finest games of chess.
Malcolm Pein Follows…A Nunn on a Run
was staged by the British Chess Problem Society on Zoom rather than face to face and run as a fun event with no prize money. Yet again, John Nunn won the competition with 60 from a maximum of 65 points, making just one error in the 13 problems set. Eddy van Beers (Belgium) and Martynas Limontas (Lithuania) matched Nunn’s score, but couldn’t match him for speed, as Nunn used just 120 minutes from the available 230.
Here is a beautiful endgame study from the competition. Composed by V.Bron and first published in Shakhmaty v SSSR #544, 15.08.1931. White to play and win. If White can save his dark bishop, the three minor pieces will prevail over the rook.

White to play and win
Nunn, who lives in Bude, is one of the few people to hold the Grandmaster title in over-the- board chess and problem solving.
