B01 Scandinavian Defence (1.e4 d5 2.exd5 Qxd5 3.Nc3 Qa5 4.d4 Nf6 5.Bd2 c6 6.Nf3 Bg4 7.Be2 Nbd7)

The game below is from the second round of the WORLD OPEN RAPID tournament that was played at the FIDE Online Arena though as I had analysed quite a lot of those games in advance from there, so I wanted to see if I can find opening variations that I had not covered before faster. And by saying that I analysed those games before, I meant that I had used the Full Analysis function of the Deep Fritz 14 64Bit version on many games but I had not yet looked up the opening played in the games. The game below I remember partly and the part I remember about is the move 41.Kf1?? because I made the move quite fast and almost immediately realized how bad it was. I could not believe I had missed the way to draw this. After I had played that move I was convinced that I am going to lose but I had to see what happens. I thought that up to that point I had played well and then I blundered the game away so close at the end. It annoyed me quite a bit and I would like to say I have learned from this game but can I avoid messing up good games like this in the future, probably not. I have added one mate in one, one mate in two, one mate in three, one mate in four and one mate in eleven today.
