Gruenfeld Defence Russian Qb3

Black is blessed with several playable options against the Gruenfeld Defence Russian Variation 5.Qb3. The trick is to keep your pieces safe and put your opponent's pieces in danger. White picked up a bishop and knight for a rook in the game between Alexey Sarana and Boris Ofitserian. Then White found a winning combination with the knight.
