B73 Sicilian Dragon: Classical System without 9.Nb3 (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 g6 6.Be2 Bg7 7.Be3 O-O 8.O-O Nc6 9.f3 Bd7 10.Qd2 a6)

My plan for this week was to add four analysed chess games and one analysed chess960 every day from Monday to Friday, but as I went through my recently ended correspondence games, I noticed that I have new opening variations to go through. It means that I will not post maybe as many games as I intended during this week, but it will be the maximum amount of games I will post per a posting day. This helps me to plan things further ahead than I would be able to in the way I did things in the past. When I have looked through all of these opening variations, I have noticed one thing that annoys me a bit, the name of the variations differ sometimes from source to source and there are other differences as well, for instance, not all of the opening variations can be found in all of the sources which in turn makes my job of finding openings played in the games all that more difficult. All I want is some consistency and a list of truly all the openings that exist in one place. Then again I have differed in the naming of some of my posts from the more usual names for the opening, the best example of this is all the posts I have named starting with Spanish Game, but I guess most people would name it Ruy Lopez. I guess the main reason for the naming was that in the original source where I looked these openings used Spanish Game, so it has stuck with me since those times.

The game below was played in a team match called Purple Bhangra punjabi style. The match was played on 33 boards between PURPLE HAZE and PAOK. I played on board 3 for PURPLE HAZE against a clearly stronger opponent. We ended up being crushed quite badly in this match as the final score 10.5 - 55.5 demonstrates. I have added one analysed game to my post: C45 Scotch Game: Schmidt Variation. I have also added one mate in two, one mate in three, two mate in four and one mate in five puzzle today.

This paragraph and the ones that follow it have been added November 25th, 2016. I was able to hang on in the game against my stronger opponent until it came time to play my 34th move in the position below. I played 34.Qe1 allowing a tactic that won the game for my opponent. I should have played 34.Qb2 to stay in the game. Note that 34...Nxd5 would be met with 35.Qh8#.

The move I played in the game allowed my opponent to play 34...Nxd5. I then took on d5 with the bishop and I was momentarily up on material. The problem with the move 35.Bxd5 is that now my opponent can invade on the second rank with the rook. I could not reply to 35...Rc2+ with 36.Re2 because then my opponent would have played 36...Qxe1! My rook could not take back because the rook is pinned. Therefore I moved my king instead. I moved my king to h3, which was probably the worst square to the king. I should have played 36.Kf1, even though I was probably lost regardless. I resigned after 37...Qh8+ in a position where I was still up in material, but I faced a forced mate.
