B40 Sicilian: 2...e6, Unusual lines

B40 Sicilian: 2...e6, Unusual lines

I am back into posting after using my time to other things for awhile and this time the posts will be published more regularly than in a long time. The posts should be appearing five times a week again. I am still going through my previously posted games and changing the names of the openings played in the games according to how Deep Fritz 14 categorizes them. When I get far enough in the future with these improvements, I will also start adding new Chess960 games to look at. Also when I get things going properly again, I will start doing videos to YouTube again.

While Deep Fritz 14 classifies this opening to include the move 5...c5, it is not the best move. Moves like 5...Nf6 and 5...Be7 are better according to the engine Stockfish 8 64 POPCNT. My opponent should have been in some problems after the 5th move, but in the position below my opponent made a move that could have cost Marko Krale the game. My opponent played 8...Qc7 and with correct play I would have been on my way to victory. I played 9.Bd3 in the game, which was not the best decision. I should have played either 9.O-O-O or 9.Bf4. After my 9th move the position should be slightly better for me. In order to keep the situation in control, my opponent should have played 9...Nd7, but he played 9...Nc6 instead, which allowed me to increase my advantage again with the move 10.Nxc6.

The next turning point came when we reached the position that can be seen in the diagram below. I played 13.Bd3 in order to save my bishop pair, but it was more important to get a new piece into the game. In reply Marko Krale played 13...h6, which was a bad choice. Because my opponent was clearly behind in development, it was important to get pieces out as fast as possible. The move 13...h6 is just too slow. Therefore moves like 13...Bd6 and 13...Bd7 are better options than the move Marko Krale played.

The next position of interest was reached after my 18th move Qg3. It can be seen in the next diagram. My opponent decided to defend the pawn on g7 by moving the bishop to f8. It left the king in the center and development of the kingside became very difficult. It may look scary to place the king on the same file as my queen and go on the side of the board where also my bishops are aiming, but there is no real danger yet, because the kingside is sufficiently defended. The move Marko Krale played was horrible enough to result in a lost position. I took my chance to weaken the pawn structure on the kingside immediately and played 19.Bxf6, which is the strongest reply according to Stockfish 8 64 POPCNT. After the obvious 19...gxf6, I played 20.Re2, which is a step in the wrong direction. A more accurate move was 20.Bf5. That being said, I should be doing well also in the game continuation.

The next position that I am going to take out of the game was seen in the game after 20...Qb8. In the game I played 21.Qh4, in order to keep my opponent on the defensive. Had Marko Krale played 21...Be7, it would have been clearer that I made a mistake on my 21st move. Concentrating my efforts towards e6 was a better idea. After 21.Qh4, the position should be roughly even. It would have required an accurate play from my opponent and the only good move for my opponent would have been the aforementioned 21...Be7. In the game Marko Krale played 21...Bg7, which was another step towards a loss.

My 22nd move, Ne4, was a bad idea from me, which would have let my opponent back in the game, had he played either 22...Qe5 or 22...Qd8 in reply. 22.Qb4 was my best choice. Neither 22...Qe5 nor 22...Qd8 was played, my opponent instead chose to play 22...Bxe4, which is one way of protecting the pawn on f6, but not a good one. The light-squared bishop could have offered my opponent some counterplay especially if combined with the rook on the half open g-file and perhaps with the queen. I then should have taken the bishop with my queen, in order to centralize it and prevent my opponent from castling. I instead played 23.Rxe4 and the game was quite evenly played for a little while. The next turning point came in the diagram position below.

Marko Krale did not castle, but instead moved the queen to c7 on move 24. Maybe he thought that the king is more secure on e8 than on g8, which I can understand to some degree, but since there was a clear threat of Bxf5, I would have taken my chances and castled. I happily took the free pawn and probably was confident about my chances of winning the game at that point in the game. My opponent blundered with 25...Rd8 and at that point I had the chance to force a mate in four. This was definetely my best chance to win the game, but unfortunately I missed the mating sequence and made things unnecessarily difficult for me. The game continued favorably for me even after that with the moves 26.Rxd8+ Qxd8, but then I traded queens and the game seemed to go towards a draw from that point on. The next diagram shows the position after 32.Re3. It was in this position that my opponent started to give me play again and maybe with accurate play, I could have even won the game.

The game game continued with the moves 32...Bg7 33.Bd3 Ra1 34.a4 Rd1. With each of his three moves, Marko Krale made his position worse. I was not making the best moves either and instead of 34.a4, I should have played 34.Rf3. I played it a move later and it was still a good move, keeping me firmly in the driver's seat. After some mistakes from both sides, we reached the position seen in the diagram below, taken after 40...Be5. I played 41.Rd3+ and the game went on peacefully and draw was agreed upon on move 50.

This paragraph was typed when I originally shared this game. This is from the 2014 August Grand Seven Fourteen III tournament that is still ongoing at Red Hot Pawn. I had my chances to win this game but I was not able to take advantage of them and the game ended in a draw. I may have a pawn more in the end position but I do not have any way to improve my position as my opponent's pieces are restricting my actions quite a lot. So he has enough compensation for the pawn to draw this game with ease.

B01 Scandinavian Defence (4.Nf3)

B01 Scandinavian Defence (4.Nf3)

The game I am sharing today was originally in the post B01 Scandinavian Defense: Mieses-Kotroc Variation. The new naming method will mean that there is no longer a post named like that. This game was played reasonably well until my opponent played 38...g5 in the diagram position below. Before that neither player had made any major mistakes. The problem with the move 38...g5 is that it loses a pawn by force. Or rather it would lose a pawn by force in case the player controlling the white pieces would play accurate moves. The loss of a pawn would mean a loss for my opponent, but apart from my reply 39.Rb5, I was not able to play correct moves. Marko Krale then played 39...Kd6 and now had I continued with 40.Rb6+, I would have been on my way to victory. In the game I played 40.Rb7, which allowed my opponent to get back into the game.

The game did not continue evenly all that long, because Marko Krale's 42nd move was a horrible blunder that allowed me to take the winning advantage once again. The problem with the move 42...Ke7 is that it gives me time to play 43.fxe5. Had my opponent moved his king to c7, I would not have had time to take on e5. The game continued with the moves 43...Rh4 44.Rc6 Rxh3+ and then I threw my win away again with the move 45.Kf4. The position was roughly even after that.

The final downhill began for Marko Krale when he played 46...Ke6. I replied correctly with 47.Rc6+ and then my opponent made the final mistake 47...Kf7?? After that the game quickly ended in my favor.

This paragraph was typed when I originally shared this game. The game below is from a tournament called 2014 August Grand Seven Fourteen II. I have still five games in progress in this tournament and I am still in the fight for the win. I might be quite close of reaching the best tournament score I have ever had at Red Hot Pawn but it can still go horribly wrong of course, nothing is all that certain at this point.
