C41 Philidor Defence (1.e4 e5 2.Nf3 d6 3.Bc4 Be7 4.d4 exd4 5.Nxd4 Nf6 6.Nc3 O-O 7.O-O)

The games from the 100 game match have been very good at offering new opening variations to show in this blog and I think it will be the case for the rest of this week, though there will be other games to look at aswell. I continued taking even more considerable lead in the match as this win brought me a seven point lead. The score after this was 23.5 - 16.5. Was this the most crusial part of the match or will the score be turned the other way around, only time will tell. This 40th game was not the last one before we paused the match, I think we finished the 51st game before the match was paused. Not sure when we are going to continue playing the match but maybe next week would be a good time for that again.

I might start playing games at the FIDE Online Arena again today, but first I need to find something to post on Friday and maybe even start looking for something to post next week. Until tomorrow, my fellow chess enthusiasts!
