A16 English Opening: 1...Nf6 with ...d5 (1.c4 Nf6 2.Nc3 c5 3.g3 Nc6 4.Bg2 g6 5.Nf3 Bg7 6.O-O O-O 7.e4 d6 8.a3)

A16 English Opening: 1...Nf6 with ...d5 (1.c4 Nf6 2.Nc3 c5 3.g3 Nc6 4.Bg2 g6 5.Nf3 Bg7 6.O-O O-O 7.e4 d6 8.a3)

The game below was played in the 2014 September Grand Seven Fourteen III tournament. I have gathered 85 points so far and I can get to 103 points if I win my last six games. I am currently on fourth place but I can end up anywhere from second place to sixth place depending on what happens on the remaining games. In three days, I have gone from 169 games in progress to 159 games in progress which is a very good sign. Games might end in a decent pace in the nearish future aswell, so maybe I could get under 100 in July. I have added one more analysed game to the following posts today: A00 Mieses Opening: Reversed Rat, C62 Spanish Game: Steinitz Defense and D45 Semi-Slav Defense: Main Lines. I have also added two mate in twos, two mate in fours and one mate in six. Until tomorrow, my fellow chess enthusiasts!

The first sign of trouble for my opponent came when adalia bipunctata played 9.b4 in the position below. It was a better idea to play 9.h3. One of the problems with the move 9.b4 is that it loses a pawn in the game continuation 9...cxb4 10.axb4 Nxb4 11.Qb3 a5. My 9th move was not the best, 9...Nxe4 was a much stronger move and the game might have been quickly over had I played it.

Even with the move I played in the game I was clearly better for a few moves. When I played the move 12...Qc7 in the position below, my advantage decreased into a small one. 12...Rc8 and 12...Nd7 were better options.

Adalia bipunctata then made the game losing blunder 13.d5. It gave me another opportunity to play 13...Nxe4! Given enough time, even I can find a good move and I did play the move 13...Nxe4 in the game. My opponent never recovered and ended up resigning the game after my 37th move d4+.
