C50 Hungarian Defence and Giuoco Pianissimo (1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.O-O d6 5.h3 Nf6 6.Nc3 a6 7.Re1 O-O)

This may come a bit later than usual but I still managed to get a daily update done. I have not updated any puzzles today and I might only get those updated tomorrow earliest. I have been quite busy today and I still need to go through my Chess.com games before the day is done. While I tried to find a game that featured an opening that I have not yet covered, I went through three games as I thought that only the third one was something I had not featured here before, but actually I was wrong in my assumption. The game below is the second game I went through and thought that I had done this opening already, but when I searched through all the posts I have done, I could not find it. Good news is that now I have a game to share tomorrow, day earlier than usual.

The first move that seems a bit odd to me, is the move 8.b3 and actually it is a novelty according to my reference database. Paulsains wanted to fianchetto the dark-squared bishop, but it does not look like the right idea when the other bishop is at c4. I replied with 8...Nd4, which placed the knight to a more active position and to a square from which it could not be driven out with a pawn so easily. Paulsains then traded the knights and I took back with the bishop, which left it to an excellent square. At d4 the bishop restricted the movement of both the knight on c3 and the pawn on f2.

Then my opponent finally placed the bishop to b2, which was the first step in getting out of the pin and trying to challenge the bishop at d4. I followed it up by moving developing my bishop to e6 and Paulsains exchanged the bishops on e6. It generated doubled pawns on the e-file for me, which I was content with because it also opened up the f-file to my rook's disposal. The rook on the f-file and the strong bishop at d4 could generate an attack towards f2.

In the diagram position above Paulsains played 14.Ne2, which was the game deciding blunder that allowed me to take on f2 with my bishop. My opponent did not resign so easily though, Paulsains kept on playing even after I won a piece in a position where I was up two pawns. My opponent continued the struggle up to the move 27...g6, but then decided that he or she had enough and resigned.
