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.

B00 Queen's Fianchetto Defence, Nimzowitsch Defence (7...Bb4+)

B00 Queen's Fianchetto Defence, Nimzowitsch Defence (7...Bb4+)

The more detailed look at my previously shared games continues with this post. It really annoys me that I could not do the original post like this, so that I would have only needed to change the name of the opening used in the game and not do most of the work from scratch. The first position that I like to show can be seen in the diagram below. It is taken after my 9th move O-O. In this position my opponent played 9...d6. It is a huge blunder and could have been the losing move. I was not aware of my possibilities and played just a normal developing move 10.Nc3. The move that I should have played was 10.d5! It seems so obvious now, but apparently I was not paying attention to the situation on the board and just played a move that seemed not to lose...

My move was okay, but had I played 10.d5, I would have had a winning advantage. Alfito2012 replied with the move 10...O-O, which could have been a problem for my opponent, but because I played 11.a3 instead of the correct move 11.e5, the game continued more evenly than it should have. The next diagram shows the position after 23...Bxd5. This was the position in which I played my losing move 24.Bxd6?? It was replied with the crushing move 24...Nxe4 and the game was quickly over.

This paragraph is taken from the original post and therefore it is in some ways out of date. This game is from a team match called Mount Doom. The match is played on 30 boards between Lord Of The Rings and Team Latinoamérica. I am playing on board 3 for Lord Of The Rings, my other game against alfito2012 is still in progress. This has been quite evenly played match as the current score 23.5 - 22.5 demonstrates. The score is in favor of Lord Of The Rings. We still need seven points to secure the win and maybe I can help in that effort, I certainly would like to be able to do so. However, due to my recent game results, I am not at all sure what will happen in any of my games as it would seem to me that I can mess up almost every game at this point in time.
