C41 Philidor Defence (1.e4 e5 2.Nf3 d6 3.d4 Bg4 4.dxe5 Bxf3 5.Qxf3 dxe5 6.Bc4 Nf6 7.Qb3 Qe7)

C41 Philidor Defence (1.e4 e5 2.Nf3 d6 3.d4 Bg4 4.dxe5 Bxf3 5.Qxf3 dxe5 6.Bc4 Nf6 7.Qb3 Qe7)

The things typed after this sentence were typed when I originally shared this game. This was played at ChessRex.com. This was a correspondence game and both players were able to use 7 days for each move. The interesting thing is, I had faced the position after 10.Bd2 in a game I had played a couple of months before this game in a team match that was played over the board. Not only that but I also faced the same position in another game at ChessRex.com. In all three games the move order was exactly the same. When I reached the position after 7...Qe7, I was annoyed that I had not analysed the over the board game because I had thought about two moves here, 8.Qxb7 and 8.Bxf7+. Despite having thought about those possibilities, I did play 8.Qxb7 in all three games though I did consider Bxf7+ maybe better, but I was not confident enough to play it, mostly due to the fact that I do not trust my calculation skills. I did check those possibilities with Stockfish 6 64 BMI2 now and it first thought that Bxf7+ is better, but after some time it decided that Qxb7 is clearly the better move. Like I have previously typed, the move 6...Nf6 is the losing move of the game. The rating shown in the notation is my current rating there after two games. That is also the only rating you get there, it does not matter if you play chess, chess960 or the times you are using for the game, the rating is still the same. It is the only site where I have played that uses only one rating for players. It is certainly something that makes it stand out from other sites. The first time I noticed only one rating for players, I had to ask about the rating thing in the lobby, because I could not believe it. I actually embrace these different ways to do things, it is refreshing to me.

Game number two. This game had a very similar start as the previous game in this post. I was rather surprised of that fact, but also because these two games followed a game I had played in a over the board team match couple of months before these two games started. These two games that were played at ChessRex were quite easy because of that earlier thought process I had done during that team match. Of course all these games did deviate from each other at some point, but I think it was this second game that followed more closely to the over the board game.
