Chess may not still be completely figured out game but there has been millions of games where players from all over the world have made their attempts to the possible solutions. Every chess game that has ever been played or will be played is just one more solution to the game, how ever faulty they may be. I have only participated to this mass solution with mere few thousand wrong solutions and will continue bringing those as long as I live.

From my move five onwards I played sloppy moves that brought me into problems, but it was only when we reached the position below that I started to slip from a possible draw. The position below came to the board after my opponent played 12.Nxd5. I had two possible replies, 12...exd5 and 12...Qxd5. Unfortunately I chose the latter because I wanted to keep my pawn structure intact, but it was a bad decision.

The move I played in the game had the big downside of leaving the light-squared bishop behind the e-pawn and making the devolepment of my queenside pieces rather difficult. From that point on I struggled a lot, but refused to resign. My efforts to resist the inevitable loss were rewarded at last when fledermaus played 49.Be6 in the position below.

After that mistake the game was fought evenly to the end. Allowing me to bring my king to b5 made it possible for me to capture the extra pawn and drawing the game was easy after that.
