D00 1.d4 d5: Unusual lines (1.f4 d5 2.d4 Nf6)

In order to balance the scale a bit I have to post this loss of mine. Since I posted a win against this same opponent earlier today, I thought as this was conveniently already analysed that I would put this game here today as well. There is also something interesting about today that I wanted to share with the readers. Today was the second time this year and actually the second time in my so called chess career that I was able to beat an International Master. The first win over an IM came in the Finnish Team Blitz Championships, so one win over the board and one in the internet. I do not think I have improved that much in chess that beating IMs would become a regular thing, not by a long shot, so I need to be happy about those rare moments when those things happen. I will post that game later on in this blog with full analysis.
