The notes with the game are extensive, but for improvement purposes I want to highlight the defensive resource I found on move 36 as a concrete example of how my training and studies have helped my game. I correctly anticipated my opponent's threat and calculated the sequence, most importantly not prematurely ruling out the tactic, which immediately returns the sacrificed piece. Before I would not have considered a broad enough spectrum of options, I believe, having previously been too closed-minded about tactical possibilities and my thinking process.

A10: English Opening: Unusual Replies for Black 1.c4 f5 2.Nf3 Nf6 3.g3 b6 first time I've seen a queenside fianchetto this early in a Dutch Defense
style game. 4.Bg2 Bb7 5.0-0 e6 a major decision point in the opening.
Examples of the two other main choices: 5...c5 6.d4 e6 7.d5 Qc8 8.Nc3 Be7 9.e4 0-0 10.e5 Ne8 11.Re1 g6 12.Bh6 Ng7 13.Qd2 Re8 14.Ng5 a6 15.Rad1 Ra7 16.Bf3 Bf8 17.Bg2 Ba8 18.b3 Qb7 19.a4 Qc8 20.h4 Balinov,I (2454)-Kummer,
H (2335) Vienna 2006 1-0 (33) 5...g6 6.b4 Bg7 7.Bb2 0-0 8.Qb3 h6 9.Nc3 e6 10.d4 d6 11.Rfd1 Qe7 12.c5 Bxf3 13.Bxf3 d5 14.Nxd5 exd5 15.Bxd5+ Nxd5 16.Qxd5+ Kh7 17.Qxa8 Qxe2 18.Bc3 Nd7 19.Qg2 Nf6 20.d5 Antoli Royo,J
(2410)-Sierra Aguerri,J (2068) Zaragoza ESP 2011 1-0 6.b3 I like the a1-h8
highway into Black's camp, which is currently there for the taking. Na6
now out of the database. This doesn't do much for Black's development. 6...Be7 is the logical follow-up to e6. 7.Bb2 7.Nc3 would postpone
committing the dark-square bishop. 7...Bd6 apparently played with the idea
of contesting e5, this blocks the d-pawn and puts the bishop on a less useful
diagonal than it would find after Be7. I'm assuming my opponent was planning
to retreat it along the diagonal and then play ...d5, as occurred in the game,
but this is a very slow plan and the negatives outweigh the positives for
opening development. 8.Nc3 c6?! although this takes away b5 from White
and opens a retreat to b8/c7 for the bishop, the fact that it buries the Bb7
means it's a net plus for White's position. 8...0-0 9.a3 takes away the
b4 square from Black's pieces, without any nasty side effects. Rc8 by this
point, I am wondering why Black is delaying castling, as keeping the king in
the center does not gain him anything and can only help White. 10.b4
gaining queenside space and taking away the c5 square from the Na6. 10.d3
immediately does more for White, taking away the central e4 square from Black
and preparing to push the e-pawn, which would open the game to White's
advantage. For example 0-0 11.e4 fxe4 11...Bb8 12.exf5 exf5 13.Nd4± 12.dxe4 Bb8 13.e5 Ng4 14.Qe2± and after following with Rad1, White
dominates the center and the d-file and can shift his forces easily to the
center and kingside, while Black's two bishops and the Na6 are not doing much. 10...Bb8 Black's plan is now obviously to follow up with ...d5. 10...0-0 11.d3 11.e4 is the more direct way to take the battle to Black. fxe4 12.Ng5 0-0 13.Ncxe4± 11...d5 Black appears to still be deliberately
avoiding castling, most likely with the idea of eventually using the rook on
the h-file as part of an attack on White's king. Incidentally, Black now has a
Stonewall formation, but with his queenside pieces looking uncoordinated and
cramped. 12.e3 the idea being to prevent an ...f4 push by Black, although
this is not a real threat. 12.cxd5 begins a forcing sequence which I
hadn't considered during the game. cxd5 12...exd5 13.Bh3± 13.Qa4+
the Black bishop cannot interpose on c6 because of the hanging Na6 Qd7 14.Qxd7+ Kxd7 15.Nb5± with easy play for White. 12...Rc7?! Black
temporarily takes away the last remaining square for the Na6 and blocks the
Bb8, although the rook will transfer itself on the next move. 13.Qb3
I choose to keep the tension in the queenside and center, also developing the
queen to a useful square. However, with Black's king uncastled, his queenside
pieces in each other's way, and a weakness on e6, this would also have been a
good time for me to open the center up. 13.Nd4!? 13.cxd5 13...Rd7 14.Rad1 14.Rac1 would target the weaker c-file. 14...c5? the advancing
pawn gives up key squares to White without a fight. 14...0-0!?
and Black is still in the game, says Houdini via the Fritz interface. 15.b5 Nc7 16.Ne2± opens up the long diagonal for the Bb2 and eyes d4 and f4. 16.Ne5! takes more direct advantage of Black's weaknesses. One possible
continuation is Re7 17.d4 cxd4 18.Rxd4 0-0 19.Nc6 Bxc6 20.bxc6 dxc4 21.Qxc4 Qc8 22.a4 Rfe8 23.Ba3 Rf7 24.Rfd1+- 16...dxc4 17.dxc4 Rxd1?
this gives up the d-file, a dangerous choice. 17...Bxf3!? exchanging off
White's excellent attacking piece would be preferable. 18.Bxf3 0-0± 18.Rxd1+- Qe7 19.Nf4 19.Ne5!? instead would immediately give White a
dominant central knight. Bxg2 20.Kxg2 0-0 21.Nc6+- Qe8 22.Bxf6 gxf6 22...Rxf6? 23.Rd8 23.Rd3 Na8 24.Qd1+- 19...Na8 buries the knight
in the corner, but at least lets the Bb8 be of some use. 20.Nd3 played with
the idea of avoiding the bishop for knight exchange on f4 and obtaining a lock
on e5. 0-0 it makes sense to castle now, but why not earlier? 21.Nde5
similar to how it seems that in the post-game analysis it's revealed that you
always move the wrong rook, here it's the wrong knight. 21.Nfe5 Bxg2 22.Kxg2 Qb7+ 23.Nc6 gives White a more dominating central position. 21...Bd6 21...Rd8 now that the rook is available for battle after castling, it
should be put in play. 22.Nd2?! this passive retreat simply dissipates a
large chunk of White's advantage. 22.Qd3 Bc7 22...Rd8? 23.Ng5 Bxg2 24.Kxg2 with knight fork threats on f7 and c6. 23.Ng5 Bxg2 24.Kxg2 Bxe5 25.Bxe5+- 22...Bxg2 23.Kxg2 Bxe5 24.Bxe5 if this is contrasted with the
position in the above variation, it's then easy to see that here White's
pieces are not nearly as well placed. Qb7+ 25.f3 Ng4 this one-move threat
(due to the pin on the f3 pawn) was seen coming. Although it looks threatening,
the Ng4 is actually doing very little and will quickly be evicted. 26.Bb2 Re8 27.h3 Nf6 27...Nh6 28.e4 28.Kf2 White decides to move out of the
pin before proceeding further. 28.Bxf6 gxf6± was a possibility and is
preferred by Houdini, but I didn't see how White could effectively exploit
Black's pawn structure weaknesses. 28...e5 28...Qf7 would have shored up
Black's kingside. 29.Nb1?! this is too slow and allows Black to equalize. 29.Qc2 retains the advantage by bringing the queen back into play along the
key b1-h7 diagonal. Qc8 30.g4 fxg4 31.hxg4± 29...Qe7 30.Nc3=
now although the engine rates the position as equal, it's Black who is gaining
the initiative and placing his pieces so that they can cooperate and target
the center. Nc7 31.Ne2 Rf8 32.Rd2 32.Kg2 moves out of the line of fire. 32...g5 an ambitious move, if not completely justified. 32...Nce8 33.Qd1 32...Qe6 33.Qc3 e4 34.f4 33.Qd1 I was set on the idea of doubling on
the d-file, which however is well-defended, missing the better idea of setting
up a battery on the a1-h8 diagonal. 33.Qc3 33...Qf7? a cheap
threat against c4 that is swiftly punished. My opponent evidently believed
that his follow-on move would be devastating, but it doesn't work. 33...g4 would generate more pressure, although White could hold with 34.Ng1 34.Bxe5± Ne4+?? a game-losing miscalculation by my opponent. 34...Nce8± 35.fxe4+- fxe4+ 36.Nf4! evidently this was missed by Black. gxf4 37.gxf4 the extra protected passed pawn and ability to penetrate Black's
position mean that White will win. Ne6 38.Rd7 Qf5 39.Qg4+ Qxg4 40.hxg4
and my opponent flagged in a losing position, not finding any good
alternatives. 40.hxg4 Rf7 41.Rxf7 Kxf7 42.f5+- 1–0
