In the A-group both Jan Werle and Jorden van Foreest won their games. Jorden scored a rather straightforward win against Davit Lobzhanidze. Jan had to fight ferociously and was lucky that opponent Sergey Kasparov blundered in the end. After sacrifising a rook, then a piece and regaining material the White-Russian GM found himself a piece down compensated by three extra pawns. It was an endgame that should have ended in a draw. Kasparov complained that his opponent had played on too long, but he had better concentrated on the game. It was a neatly constructed self mate by Kasparov that brought Werle his victory.

IM Migchiel de Jong scored a fine win against GM Roeland Pruijssers. Migchiel has 5 points, GM Sundar Shyam joins him in 2nd place.

The all important fight in teh C-group to leave the bottom of the list between Janneke van der Hagen and Mandy Zheng was won by Janneke. Mandy stayed unshaken.

In the game S.Kasparov - Werle white sacrifised a full rook on move 16.

After 15..fe6x 16.ab5x Qa1x 17.0-0 Kd7 18.Bb4x Bb4x 19.Ng5x the  computer suggests 19..Pe7 en 20...h5 as black's best answer, but Werle chose for returning the rook, where 19..Kc7 20.Ne6x+ Kc7 and 21...Kb8 would have given white something to think about. A nearly endless number of checks followed. 

Eventually an endgame R+B against R+ 3p evolved. 

White should have played 82.g5+ Bg5x 83.Rb6+ and 84.h6 to sacrifise his last pawn and reach the drawn endgame R+B against R. Still quite a task when black has 50 moves to prove his point.  But after 82.Rb6+ Bd6 83.g5+ Kh5x white had to resign.
