A06 Réti Opening: 1.Nf3 d5 (1.Nf3 Nf6 2.b3 g6 3.Bb2 Bg7 4.e3 d5)

A06 Réti Opening: 1.Nf3 d5 (1.Nf3 Nf6 2.b3 g6 3.Bb2 Bg7 4.e3 d5)

This is one of the openings determined by Deep Fritz 14 in which the name of the opening is the same, but where the amount of theoretical moves differs from other games where it also says the opening to be A06 Réti Opening: 1.Nf3 d5. I am not sure if I should put all of those games in the same post or not. I have put only the games that have the same amount of theoretical moves in the same post and the exact same moves Deep Fritz 14 thinks to be theory in brackets in the title of the post. And yes this game has also been previously shared in this post. There will not be probably new chess games appearing to the blog before I gone through all the chess games already shared in the blog and have made the necessary changes to them. However, I could add new Chess960 games from time to time. I can't really promise a steady flow of blog posts or videos to my YouTube channel, this is all a big mess at the moment and sorting things out will take time. It has already taken way too long to my liking, which in turn makes it feel overwhelming and frustrating at times. I apologize for the long breaks between content and I thank you for your patience.

This was played in the "atadros's mini-tournament V". Out of the 20 games I played in the mini-tournament I was able to win only 2, I drew 7 and lost 11 games. The 5.5 points I was able to gather were only enough for me to be 9th in the final standings. My opponent in this game, danyfox, won 4 games, drew 2 games and lost 14 games. With 5 points danyfox was 10th in the final standings.

I was quite close to a clear advantage couple of times before danyfox's 17th move in the position below, but the first severe mistake was that 17th move Qc4. The best move for danyfox was 17.Nf3. 17.Qc4 could have been the losing move and at first I chose the correct move 17...Na5. In that position I should have a winning advantage according to Stockfish 8 64 POPCNT.

The game went on clearly in my favor, though I did some inaccurate moves, until we reached the position below. In that position I threw my winning chances away by playing 31...Kf8.

I had a few good moves to play instead, for instance, I could have played 31...Bf8, 31...Rxc8 and 31...Rde7. Danyfox found the best move 32.e5 in reply and the game reached equality. We played a few more moves, but we agreed to a draw after 35.f4.
