A38 Symmetrical English vs ...g6: 4.Bg2 Bg7 5.Nf3 Nf6 (1.c4 c5 2.Nc3 g6 3.Nf3 Bg7 4.g3 Nc6 5.Bg2 Nf6 6.O-O O-O 7.d3 d5 8.cxd5 Nxd5 9.Bd2 Nc7)

It has been so long since the last time that some variation of the English Opening has been covered here that I can't even remember it. It would easy to find out that information of course but I am not going to do that now. Today was quite a busy day, I needed to analyse some of my games in the database, go and try to teach some chess at the high school and make moves at my correspondence chess games and post nine other games before it was time for this game. As I am not all that verbally talented as you might have noticed if you have been visiting this blog before, it is quite a time consuming process to type these blog posts. And even then they might not be the most interesting ones that you would see somewhere else. I would like to think that the games at least are interesting that I am posting here. I am aware that it does hold true for all of the games but there are some that I personally enjoy and maybe you could enjoy some of them as well. I have added two mate in ones, one mate in two, one mate in three and one mate in five.
