A38 Symmetrical English vs ...g6: 4.Bg2 Bg7 5.Nf3 Nf6 (1.c4 c5 2.Nc3 Nc6 3.g3 g6 4.Bg2 Bg7 5.Nf3 Nf6 6.O-O O-O 7.d3 d5 8.cxd5 Nxd5 9.Nxd5 Qxd5)

There may have been too many posts about Symmetrical English lately, but this may be the last one for awhile. This is also a return for the games that have not been previously shared, for the time being that is. This is a blitz game I played at Chess.com on July 19th, 2016. The move statistics do not go beyond the move 9...Qxd5 because my opponent's 10th move, Ne1, was a novelty according to the LiveBook. I also searched that position in my reference database and the move 10.Ne1 had been played 3 times with the score of 0%, which means that in all of those 3 games the player controlling the black pieces won the game. We kept following one of those three games and part of that game can be seen in the notation.
