A39 Symmetrical English vs ...g6: 4.Bg2 Bg7 5.Nf3 Nf6 6.O-O O-O 7.d4 (1.Nf3 Nf6 2.g3 g6 3.Bg2 Bg7 4.O-O O-O 5.d4 c5 6.c4 cxd4 7.Nxd4 Nc6 8.Nc3 Nxd4 9.Qxd4 d6 10.Qh4 Rb8 11.Bh6)

This is the 43rd game in the 100 rapid game match that was played between these two players. This was also the sixth game in a row where I avoided losing. That six game streak had 3 wins and 3 draws in it. After the game below my lead in the match increased to 8 points and the score was 25.5 - 17.5.
