The game itself contains some interesting ideas (not just psychological ones), including alternatives for Black on move 9 and move 12. As part of the analysis process, it's very useful to see how modern engines (Komodo 10 in this case) help evaluate plans, not just individual moves; for example, it consistently highlighted the value of the b8-h2 diagonal and building up pressure on it through the variations on moves 12 and 15. I also like the idea of the knight retreat on move 19, getting out of the way of the pawns and playing a more maneuvering type of game. Finally, it was worth looking at the different options towards the end of the game, for both dynamic and maneuvering play, to continue working my positional advantage.

1. d4 d5 2. e3 {usually an indicator that White is heading for a Stonewall
formation.} Nf6 3. Bd3 c5 4. c3 Nc6 5. f4 Bg4 {getting the bishop to an active
square before playing ...e6} 6. Nf3 e6 7. Nbd2 Be7 8. O-O O-O 9. Qe1 cxd4 {
Normally it's a good idea to exchange c-pawn for d-pawn, and it isn't bad here.
But there may be a more effective path forward for Black.} (9... Bf5 {is a
more sophisticated positional idea, which is both the database and engine
favorite. After} 10. Bxf5 exf5 {Black has a lock on e4 and White's e3 pawn
will be weak on the half-open file.}) 10. exd4 Rc8 11. Ne5 Bf5 {I'll give
myself credit for recognizing this idea, even if a bit later than optimal.} 12.
Qe2 a6 {this was perhaps a waste of time. My idea was to play follow up with ..
.b5 and prevent White from advancing the c-pawn to exchange off my d5 pawn.
However, this is not a real threat as long as the Nc6 is there (due to the d4
pawn then being unprotected). If White exchanges on c6, then a subsequent pawn
swap on d5 would just leave d4 isolated and weak.} (12... Qc7 $5 {would
develop the queen and connect the rooks. It also starts to build pressure up
on the b8-h2 diagonal.}) 13. Qf3 b5 {sticking with the original idea.} 14. a3
$6 {done to prevent b5-b4, but this is too weakening.} Na5 $15 {now having a
pawn on b5 is actually helpful, thanks to my opponent making holes on the
queenside.} 15. Re1 Re8 {not really necessary. Komodo still favors the plan of
building pressure on the b8-h2 diagonal with ...Bd6 and ...Qc7.} 16. g4 Bxd3
17. Nxd3 Nc4 18. Nxc4 bxc4 {now I enjoy a significant space advantage in the
center and on the queenside.} 19. Nf2 g6 (19... Nd7 $5 {would activate the Be7
and give White fewer kingside targets for the pawns.}) 20. Qh3 (20. f5 exf5 21.
gxf5 Rb8 $15) 20... Bf8 {rather too cautious.} (20... Rb8 {with the idea of
pressuring the b-pawn and forcing White to tie down a piece to its protection.}
) 21. Bd2 $6 {White will just have to move this back next move.} Rb8 $17 22.
Bc1 Qb6 {here either more patience was called for in a largely closed position,
or some more dynamic play.} (22... h5 $5 {is the dynamic option.} 23. gxh5 Nxh5
$15) (22... Re7 {is a more slow maneuvering approach, clearing the e8 square
for the knight to go to d6 and perhaps to double rooks on the b-file.}) 23. Qg3
Bd6 24. Qf3 {at this point I saw no obvious breakthroughs for Black, so took
the draw. Basically a lack of energy and patience was the reason, along with
not really understanding the needs of the position. These include the
importance of the b8-h2 diagonal and activating the bishop, the possible ...h5
advance, better and earlier development of the queen and rooks, etc.} 1/2-1/2
