A43 Schmid Benoni (1.e4 e6 2.d4 c5 3.d5 Nf6 4.Nc3 d6 5.Nf3)

This game features an opening variation that was played in a move order that you will not see in theory. The theoretical move order for this variation is 1.d4 c5 2.d5 e6 3.e4, you might also come across this variation with the name A43 Benoni Defense: Franco-Sicilian Defense. The game below was played in the third round of a rapid chess tournament that was played at FIDE Online Arena on April 7th 2015. On the previous two rounds I won a game against a lower rated opponent and lost a game against a higher rated opponent, so the tournament was going once again without any real surprises and this third game did not break that pattern. I have added two mate in two, two mate in four and one mate in six puzzle. I have also added one more analysed game to my post C90 Spanish Game: Closed Variations, Pilnik Variation.

All was well for both players until we reached the position after my 5th move Nf3 and that you can see below this paragraph. Bruno52 played 5...Nbd7, which allowed me to take on e6 without the bishop being able to take back the pawn. After the moves 6.dxe6 fxe6 7.Ng5 bruno52 played 7...Be7 and his position went further down the drain.

I typed that it should have been the losing move, but when we ended in the position below, I played 21.Be3, which would have allowed my opponent to get back into the game.

Bruno52 was not able to find the saving move and blundered the game away with the move 21...Rae8?? Bruno52 should have played 21...Nxe3 in order to fight for a draw. After this I was able to maintain my advantage and the game ended in a mate on move 31.

Game number two. This game was played on the third round of the French 2014 tournament. Up to this point in the tournament I had barely advanced from one round to the next round. On this third round I faced a bit too tough resistance and ended up being fourth in the final standings of group 2. The group consisted of 4 players, so things did not go all that well for me this round. I only managed to get half a point on round three. Lasker64 was third on the final standings with 3 points and also did not advance to the last round.

This game had a similar situation as you can see in the first game in this post, my opponent played Nbd7, which blocked the bishop's path. For some reason in the first game I understood to take on e6, but not on this game. A better alternative would be 8...Re8 or 8...exd5. Lasker64's 8th move was not as bad as the Nbd7 played in the first game of this post though. The 9th move played by Lasker64 was seen in the position below and that was the move that created my opponent some real problems. Or rather it would have created problems had I replied to 9...Qc7 by playing 10.dxe6.

I played 10.Qd2 which was not the best option, but I still remained on the slightly better side of the board. The advantage kept shifting quite a bit, but the next significant change in the advantage came only after I played 30.Qg3? The position where I played my 30th move can be seen below.

It would have been important to prevent 30...Qa1+, but I was not up to the task of playing the most accurate move. Luckily neither was my opponent since Lasker64 played 30...Qc6. The position should be quite even after Lasker64's 30th move. However, my 31st move, Bg5, threw the game away once again. Again Lasker64 played a passive move that enabled me to hang on in the game. That being said, I made a third consecutive blunder with my 32nd move, which could have allowed my opponent to take a clear advantage again. For the third consecutive time my opponent was unable to take the advantage. The move 32...f6 was good enough for a draw. Lasker64 should have played either 32...Qa8 or 32...Qa6 in order to take the advantage. The remainder of the game was played rather evenly, but I actually resigned after 40...Qe8. The reason for this was that I thought that I am in a completely lost position and could not see a saving move. There would have been a move that would have kept an even position and that move was 41.Ne4. This was not the first time that I have resigned because I have misjudged the position and it might not be the last, but I am trying my best to avoid that in the future.
