A00 Irregular Openings (1.Nc3 d5 2.e4 dxe4 3.Nxe4 e5 4.Bc4 Nf6)

A00 Irregular Openings (1.Nc3 d5 2.e4 dxe4 3.Nxe4 e5 4.Bc4 Nf6)

This game was played in a team match at between La Belle France and Вежливые люди on 11 boards. I played on board 4 for La Belle France and in addition to this draw I lost my other game. Luckily other members of the team were more alert and we won the match with a score of 16.5 - 5.5!

This line is playable up to 4.Bc4, but my 4th move is so bad that very large amount of chess players could take advantage of it. It was easy enough for my opponent to see that the reply 5.Ng5 will put me in serious trouble. I should not really play this badly anymore and if I had thought a bit longer about my move, I would have not played 4...Nf6. Alas, I these days I play the first few moves quite quickly even in daily chess, so sometimes these kind of blunders may appear on the board.

My 4th move seems to lose a pawn no matter how the game is continued, for instance, had I played 5...Nd5, the game might have continued with the moves 6.d4 Be7 and then the move 7.Nxf7 is possible. If king takes the knight, then Qf3+ wins the piece back and White is up a pawn while also preventing Black's right to castle. Other moves do not seem to prevent a loss of a pawn either, you can try them out on your own if you like, but I am not going to get further in the different possibilities. I chose to lose the pawn by continuing my development with 5...Be6. It may have been my best practical chance to get back into the game, because my opponent has only one strong move in the position, 6.Nxe6, the move that Dreadnought53 chose to play in the game, while other moves gave me a chance to fight on. Had my opponent taken on e6 with the bishop, then the game might have continued 6...fxe6 7.Nxe6 Qd6 8.Nxf8 Rxf8 and I would have had some compensation for the pawn due to the lead in development. Up to the move 8...Nc6 I was in serious trouble, but then my opponent played 9.a4, which was a rather premature pawn push, since my opponent only had a bishop developed and it did not even support the attack on the queenside because it was aimed at the kingside.

The next time that my position went down the drain was when I played 12...Qc5. It was an attractive move for me because of the threat to the a-pawn. However, the dream of getting material equality was shattered when my opponent replied with the move 13.d3. I could not take the pawn because of the continuation 13...Nxa5 14.Be3 Qb5 15.Bc4 Qb4 16.c3, for example and it becomes clear that the queen can't protect the knight on a5. Because the plan was obviously flawed, the queen is badly placed at c5 and only gave Dreadnought53 time to finish development. I continued the game by moving my knight to d5, which made things even worse for me and I was in a losing position again.

I had played very badly up to this point, but my 15th move Bh4 was by far the biggest blunder of the game up to that point. Because my king was still at c8, Dreadnought53 could have simply played 16.Qg4+ and won the bishop on h4 for free. It would have likely ended the game, because I would have resigned rather disgusted of my play. Dreadnought53 played 16.Ne4 instead, which was also good enough for a winning advantage, but enabled me to resist the inevitable a lot longer.

Up to the move 45...Kc6 I was in a losing position, but I still tried my best to hang on. My opponent then went for the move 46.R7a6+, which allowed me to fight for the draw. My stubborn resistance had finally paid off and luckily I found the most accurate move 46...Rb6. The idea was that if I can exchange one pair of rooks on my terms, the position would be much easier to hold.

Dreadnought53 did end up trading rooks and the position started to look like a draw. That being said, a few moves later my opponent was able to get a position where maintaining equality was not that simple to me and I made a mistake that created problems for me. The move 53...Kc6 I played in the game was bad because it walked into a pin and restricted my options. 53...Bc5 would have lost the game in view of Re6+, king goes either to b7 or c7 and bishop takes its undefended counterpart on c5 and the game would be practically over.

After the game continuation 54.Re6 Kc7 55.Bxf6 gxf6 56.Rxf6 fxg3 57.hxg3, it seemed obvious that I will lose a second pawn and also the game, but instead of the move 58.Rf5 that would have won the h-pawn with ease, Dreadnought53 played 58.Rh6, which allowed me to hold on to the pawn with 58.Ra5. Even though I was a pawn down, the fact that there were opposite colored bishops on board, made my job of drawing the game relatively easy.

When I started the search in my reference database for the position after 4...Nf6, I honestly thought that I would need to go games of rather low rated people, but to my surprise, reasonably strong players have also played the awful move 4...Nf6.
