Switching strategies
Ju Wenjun had switched to the Caro-Kann Defence with black and was clearly on winning after Lei Tingjie’s attacking plans on the kingside came to nothing. In fact, it was Ju who put real pressure on the opposite king with a battery of rook and queen on the second rank, while already two pawns to the good.
Out of the blue, however, Ju offered an exchange of queens: Lei accepted the offer, and in the ensuing position, the two extra black pawns were not enough to win the game. Instead of a potential 3½-3½ after the game, Lei continues to have a 1-point lead going forward!
