D00 1.d4 d5: Unusual lines (1.d4 d5 2.Nf3 Nf6 3.Nc3 e6 4.Bf4)

This one was played on the 5th and final round of a weekend tournament that was played at Kurikka over eight years ago. This win secured the shared first place for me in group B with a score of 4.5 points out of the possible 5. Due to tie-break I was second in the final standings. My only draw was against the only other player who reached 4.5 points. Due to this nice success, my rating went from 1704 to 1768.

I made a judgement error on my 12th move and went for the passive Be7 move. Up to that point no clear mistakes were made by either player. My opponent played correctly 13.Qe2 in reply and ended up clearly in the driver's seat. I made things even worse for me with the move 13...b6 and according to Stockfish, I should be in a losing position after my 13th move. Actually after I looked the lines after 14.Ne5, it does seem quite clear that I should have been lost after my 13th move. Luckily for me, my opponent was not able to find the strongest move, but instead played the move that made things easier for me.

I was still worse after 14.Nxf6+, but at least I was not losing. The inaccurate pawn grab on move 17 brought the game back into balance. White may be up a pawn, but only for a moment since I could get that pawn back. In the game continuation I did just that a few moves later.

My opponent, Vesa Leskinen, tried the move 22.O-O-O, which has the threat of Bxg6 attached to it, but this was not a good idea and it would have been better to play 22.h5, for example. However, castling was not as bad as the move he played next. My opponent played 23.g4, which sacrificed the h-pawn. Because I did not see anything horrible happening to me if I take the pawn, I played the move 23...Bxh4. The downside of the pawn grab is that it opens a line in front of my king.

I played 24...Kg7 in reply to 24.Rh3, because I thought that I need to bring my rook to h8 to protect h7, in preparation for the doubling of the rooks. It was a bit sloppy because Qe4 as a reply to Kg7 would have been enough to equalize the position. Vesa was not able to find that move and played the move I had anticipated instead. The problem with the move Rdh1 is that it is a bit slow and I have time to play Bg5+ and I have just enough time organize my kingside against the h-file aggression. 25...Bg5+ was the starting point for my road to victory. After the move 43.Qc4, I was already in a winning position, but after the even bigger blunder 44.Ba4, I could ended this game much quicker than in the game continuation. It is a shame I did not see the move 44...Rd1+, which would have either given me a lot of material or I could have delivered mate in a couple of moves.

It is quite interesting to me that quite a lot of the reference games that I have been able to find have been blitz games, like the one you will see below. So, in my long games I am able to follow the path that strong players play for a few moves mostly in blitz... Not sure what I should think about that. Then again I probably should not make any big decisions based on these very limited statistics anyway.
