B83 Sicilian Scheveningen: 6.Be2, lines without ...a6 (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.Be2 Nc6 7.Be3 Bd7)

The game below was my second game in a row against Nestor Oprysk and my third consecutive win at FOA. This game is the 1260th analysed chess game that has appeared in this blog and the 743rd (58.97%) win. Those analysed games also contain 124 (9.84%) draws and 393 (31.19%) losses. There are also 469 different opening variations covered in the blog, getting closer to 500 later this week though only by one. The most played opening variation still is A20 English Opening: King's English Variation. General, which has appeared in 45 games so far, which is roughly 3.6% out of all the games. My most successful opening variation that has appeared at least in 10 games is C41 Philidor Defense because my winning percentage is 100 in that so far after 10 games. The opening variation that has caused me most grief in the same category is C34 King's Gambit: Accepted. Fischer Defense because I have lost 45% out of the 20 games that are in the blog currently.

The game below features only one major blunder and it decided the game in my favor. The move 18...Ra7 does look like a mouse slip as there does not seem any other reason to play the rook there. At least I can't see any. The position where my opponent played his 18th move can be seen below.

I replied with 19.Bxa7 and my opponent resigned. I have added one analysed game to the following posts: C88 Spanish Game: Closed, C18 French Defense: Winawer Variation, Advance Variation #2, C42 Petrov's Defense #2 and D43 Semi-Slav Defense: General. I have added one mate in one, three mate in two and one mate in four puzzle today.
