D04 Colle System (1.d4 d5 2.e3 Nf6 3.Nf3 Bf5 4.Bd3)

Oops, this post was for a few minutes published when I was in the process of typing things for it. Maybe I am a bit sleepy because it took me awhile to see that I had accidently clicked the publish button. I just saw that this post had some views even though I thought I had not published it yet, then I realised my mistake. Oh well, no harm done, some of you might have seen some preview of the things to come but that is all.

The game below was played in the second round of third division, group 5 team match between ÅmSK and SalSK 3 over thirteen years ago. These matches are played with five player teams and I played on board 4 for SalSK 3. This was one of the two losses we suffered in this match and it was sufficient for our opponent to win the match because in the other three games, we won one and two were drawn. This meant that ÅmSK won the match 2-1 because draws are not counted in the score. In addition to all of the things I have updated today, I also finally found one game that featured a never before seen opening variation as far as this blog is concerned that is. It will be the 425th different variation to appear in this blog.
