In their search for ways to throw their opponents off balance and create unusual positions, players such as the American GM Brandon Jacobson and Magnus Carlsen have recently tried out the so-called ‘Meadow Hay Gambit’ in blitz games: 1.a4 e5 2.Ra3!? An offer to win the exchange that Black cannot really refuse though White gets a surprising amount of compensation. Gambit expert Robert Ris has now made a 60-minute video course on this variation, and ChessBase readers who want to surprise their opponents with this sacrifice – or don’t want to be surprised by it – can get this course for free now until Sunday.
