B01 Scandinavian Defence (1.e4 Nc6 2.d4 d5 3.exd5 Qxd5 4.Nf3 Bg4)

B01 Scandinavian Defence (1.e4 Nc6 2.d4 d5 3.exd5 Qxd5 4.Nf3 Bg4)

The more usual move order for this variation is likely 1.e4 d5 2.exd5 Qxd5 3.d4 Nc6 4.Nf3 Bg4. Today I accepted two chess960 challenges and in the first one I was pretty much lost after two moves... For some reason I do not look at the board properly when it comes to chess960. I guess I have played chess mostly recently and because of that I have forgotten that in some chess960 starting positions White will be able to threaten to take a pawn for free after his first move. Even if White were to take that pawn for free, it might not cost the game, but in the starting position I have in that game, my opponent was also able to take the exchange on his third move. So after three moves, he was up the exchange and a pawn, which is too much to give for almost no compensation. This might also mean that I need that break from chess more badly than I thought. Well, I should not make all that big decisions based on one game. I have mostly played on a decent level lately, maybe around 1900 level on average, at least on Chess.com and at Red Hot Pawn. Everywhere else the ratings that I have are farther away towards both directions, so I can't really compare them. I have been back over 1900 at Chess.com again for a few days now but around the time that happened, I dropped my rating at Red Hot Pawn below 1900, so that was a rather weird coincidence.

The game below was played in a team match called Happy New Year 2015 Romeo and Juliet vs Kasparov Chess Club !! The match is played on 62 boards and I played on board 11 for Romeo and Juliet. I won my both games on time. Neither of those games were actually winning for me in the position the game ended but instead close to equal. The score has not changed in the match during the time I posted yesterday and this post, so the score is still 89 - 33 in favor of Romeo and Juliet. I have added one mate in one, two mate in twos, one mate in five and one mate in seven puzzle.
