As there are some correspondence games that have finished recently, I will go through them before going to my FIDE Online Arena and over the board games. The game below was played in a small team match called Open Challenge Let's Play Benoni. I call it small because it was played on only three boards between Let's Play Benoni and Himgouree's club. I played on board 3 for Himgouree's club and won both my games against opticRED. The score at the end was 1 - 5 in favor of the away team Himgouree's club.

Some of the openings that I have seen listed in the book openings at Chess.com have a # sign at the end and if I put those in the notation, ChessBase 12 considers them as evaluation marks and puts the #3, for instance, in front of the name of the opening and I can't remove the #3 from that place of the notation anymore... Or at least I do not know how to do it. That is a bit annoying but I could of course just work around the problem by leaving the # out of the notation, which I never of course remember to do when I type the name of the variation in the notation... Well maybe next time I remember to do that and make my life a bit easier as a result. I have added one mate in two, three mate in threes and one mate in six today.
