Although disappointed in the loss, I did not worry about it too much, given the ratings differential (over 100 points in my opponent's favor) and the fact I had another three games to go. At least I had made my opponent sweat, which gave some satisfaction.

1. d4 d5 2. c4 c6 3. Nc3 e6 {the Triangle/Wedge formation. This can transpose
to various different openings and my opponent opts for an aggressive
continuation.} 4. e4 Bb4 (4... dxe4 {is most common here and may be superior,
even with the ...Bb4 idea. One recent example with Carlsen playing it:} 5. Nxe4

(2863) Lichess.org INT 2020}) 5. e5 {my opponent thought for a while here,
probably expecting that I would take on e4. The text logically grabs space and
prevents the knight development to f6, so} Ne7 6. Nf3 c5 {the correct reaction.
This break is a major theme in the line, challenging White in the center and
also with the idea of developing the other knight with Nb8-c6.} 7. dxc5 Bxc5 {
here I thought for a while, not familiar with the position. It's better to at
least temporarily sacrifice the pawn, rather than be so concerned with
immediately re-establishing material equality.} (7... Nbc6) 8. cxd5 {
psychologically this continued the pressure, with me feeling that my position
was rather open once White's light-square bishop is freed. However, I didn't
see anything real for White and this is objectively the case.} exd5 (8... Nxd5
{seemed a little loose to me.}) 9. Bd3 Bg4 {may be a little premature, as
following the usual rule about developing knights before bishops seems better.
However, in practical terms it is probably equal, since the knight development
is coming anyway.} 10. O-O Nbc6 11. Re1 {this overprotects the e-pawn, but
developing the dark-square bishop would be a more effective move.} Qd7 $6 {
at this point I had to consider middlegame plans and also how to finish my
king development. I was too afraid of castling kingside and instead kept my
options open for castling queenside with the text move. However, it is too
passive a square for the queen.} (11... Qb6 {is the logical reaction to
White's last move, which left the f2 pawn vulnerable. White would now have to
spend a move covering it, losing the initiative and allowing ...O-O.}) 12. h3 {
White calls my bluff on the c8-h3 diagonal. The bishop sac on h3 would get me
nothing, so now I have to retreat.} Bh5 (12... Bxf3 $2 13. Qxf3 {and now White
really does have an excellent attacking game on the kingside.}) 13. Be2 Bg6 $6
{unnecessary and time-wasting. White does not follow up as strongly as he
could, at least.} 14. Bd3 (14. Na4 $1 {one way or another will result in the
disappearance of the Black dark-squared bishop, currently my most effective
piece, making White's counterpart a monster. For example} Bb4 15. Bd2 O-O 16.
Rc1 Rac8 17. a3 Bxd2 18. Qxd2 {with holes on the queenside (especially c5)
that can be exploited by White's knight light-square bishop.}) 14... Rd8 $6 {
again postponing castling, to my detriment.} 15. a3 $16 {taking away the b4
square from my pieces and preparing the next pawn advance.} O-O 16. b4 {
I underestimated this. Now there is no good alternative to retreating the
bishop to b6, but I felt that would just consign me to a hopeless strategic
position. I was feeling aggressive so decided to sac a piece for two pawns
instead. This is almost never the right decision, but it seems I need to
better remember that.} Nxb4 $2 17. Bxg6 $18 fxg6 {in the hopes of eventually
generating counterplay on the f-file.} 18. axb4 Bxb4 {a good example of a
one-move threat that goes nowhere.} 19. Qb3 a5 {if my pieces were better
placed, the two connected passed pawns on the queenside might provide
compensation. However, White's pieces are much more active and mine still have
to cover too many weaknesses.} 20. Rd1 Rxf3 $5 {given the desperate nature of
the position, this is not a bad try, as it forces White to do some calculating
on the defense, after his king position gets opened.} 21. gxf3 {one problem is
that there is no good immediate follow-up. Here I decide to get my king off
the diagonal and thereby free up the pinned d-pawn. This takes too long to
allow me to make effective threats against White's king, however.} Kh8 22. Bg5
Rf8 23. Nxd5 Nxd5 24. Rxd5 Qxh3 {a last-gasp effort, although White could
theoretically still go wrong here.} 25. Rd8 Rxd8 26. Bxd8 Bc5 27. Ra2 Qg3+ 28.
Kf1 Qh3+ 29. Ke2 Qh2 30. Kd3 Qxe5 31. Re2 $2 {and he does go wrong! But under
pressure, I miss how to use my queen.} (31. Bxa5 Qf5+ 32. Ke2 $18) 31... Qd6+
$2 {now it is effectively over.} (31... Qf5+ $1 32. Kd2 {I thought this would
give White an out, but it doesn't. I suffered from "tunnel vision" and did not
consider the possibility of a bishop check, only another queen check.} (32. Kc4
Qf7+ 33. Kxc5 Qxb3 34. Re8+ Qg8 35. Rxg8+ Kxg8 $11) 32... Bb4+ $1 {now White
either has to repeat moves with Ke3 or lose the Bd8 to a queen fork.}) 32. Kc2
Qxd8 33. Qf7 $1 {White avoids the trap of being greedy.} (33. Qxb7 $2 $11 {
now Black can escape the back-rank threat various ways, including ...Bf8.})
33... Bf8 34. Re8 1-0
