1. e4 {The first little surprise. In earlier rounds in this event, Samuel had
played 1. d4 followed by 2. Bf4, and I'd spent much of the week looking at
systems to find one that seemed promising.} c5 2. Nf3 Nc6 3. Bb5 {The second
surprise. Most of the 1. e4 games I'd seen had featured a KIA style setup.
While I'd been expecting someone to try this system this year, it wasn't this
game.} g6 4. Bxc6 dxc6 5. d3 Bg7 6. h3 Qc7 7. Nc3 e5 8. Be3 b6 9. Qd2 f6 $5 {
I hadn't figured out which way White was going to castle yet, and didn't want
to tip my hand too much either. With the b6-pawn chained to the safety of the
c5-pawn for now, I figured an attack where he castles queenside and I castle
kingside was faster for him, so I wanted to leave open the option of castling
queenside. To get there, I wanted to secure e6 for the light squared bishop,
but ...h6 seemed too committal, and that it would be too difficult to castle
kingside if I needed to later.} 10. a3 Be6 11. b4 {Well, castling queenside
won't be part of the plan now!} cxb4 12. axb4 Ne7 13. O-O O-O 14. Ra6 Rad8 $1 {
The idea that Black can blunt all of the queenside pressure by sticking a
knight on c8 suggests this move.} 15. Qc1 Rf7 {This utility move provides so
many options for Black, the option of repositioning the bishop to f8 for
active duty later, brining the rook available to watch a7 if needed or to
swing over to d7 to double.} 16. Rd1 Nc8 17. Ra4 Bf8 18. Qb2 Rfd7 19. Raa1 Bf7
20. Ne2 Nd6 21. Rf1 Nc8 {My original thought with 20. ...Nd6 was that there
would be something interesting to do with the knight once it got there. But
closer analysis seemed to suggest that wasn't the case, so I put it back out
of the way.} 22. Nh4 $6 {There are a lot of moves that seemed to be just moves
waiting for me to do something at this point, but this particular one jumped
out at me as inaccurate. It seemed to me that the idea was to clear the way
for a potential f4 break at some point, but if that's the idea, having the
knight on h4 means constantly having to analyze whether ...exf4, (something)
xf4 g5 is a sound piece sacrifice or not. Rather, either 22. Nd2 (if you think
the knight will be helpful on the queenside) or 22. Nh2 (perhaps repositioning
to g4?) would be stronger.} c5 $1 {This move seemed to me to create a plan to
break through; I'd finally create a passed a-pawn, and as long as I made sure
it was strong rather than weak, I liked my chances.} 23. bxc5 Bxc5 24. Bh6 Ne7
{Taking advantage in a lull in the pressure to reposition to a stronger square.
} 25. Bd2 Nc6 26. Nf3 Kg7 27. Bc3 a5 28. Rfd1 Nd4 29. Nfxd4 $6 {I'm pretty
sure that this is the wrong way to capture. I was expecting 29. Nexd4 exd4
when the knight on f3 helps to support a later e5 break.} exd4 $15 30. Bd2 Qc6
31. Rdb1 Ra7 32. Qb5 Qd6 {I was pretty certain that the exchange of queens
would give me the only winning chances, but I wasn't sure if they were enough.
I figured that since White didn't seem to have a concrete plan rather than to
try to stop me, I could always try to exchange the queens later in a more
clear position.} 33. Ng3 {Subsequent computer analysis reveals that 33. Bb4!
is a neat equalizing shot, taking advantage of the pin on the a5-pawn to trade
off a set of bishops.} Be8 34. Qb2 Rda8 35. Qc1 b5 $15 36. Qd1 a4 {Black gains
space.} 37. Qe1 {Now that the queenside pawns need more support to keep moving
forward, time to pause and reposition.} Rc8 {This move is designed to prevent
38. Bb4.} 38. Ra2 Rac7 39. Ne2 Qe6 40. Raa1 Ba7 {At the time, I really didn't
like this move, but it seemed I needed a spot to move my dark-squared bishop
out of the way while still watching d4.} 41. c3 Qd7 42. Bf4 dxc3 $5 {The idea
of getting three connected passed pawns seemed overwhelming compensation for
the exchange, as getting rid of the c-pawn would help to let the b-pawn
through. But capturing with the rook was a stronger alternative to get to the
same goal.} 43. Bxc7 Qxc7 $2 {I had underestimated the strength of 44. Ra3!
here, and it was to the point where many evaluators had suggested that it
would be winning. In subsequent analysis, it seems like Black is able to hold
his own with 44...c2 45. Rc1 Bb8!, where 46. g3 seems relatively forced, and
that loosening of the kingside gives Black time to reposition his forces more
adequately.} 44. Ra2 $2 {I had underestimated the strength of 44. Ra3! here,
and it was to the point where many evaluators had suggested that it would be
winning. In subsequent analysis, it seems like Black is able to hold his own
with 44...c2 45. Rc1 Bb8!, where 46. g3 seems relatively forced, and that
loosening of the kingside gives Black time to reposition his forces more
adequately.} Qc5 {In retrospect, I wish I had put this queen on a5 instead,
but it seemed that I would have more options this way.} 45. Nf4 Bf7 46. Raa1 {
It seems odd to sacrifice another pawn, but software analysis is suggesting
that the light-squared bishop is so strong that 46. Nd5 might be needed to
blunt its impact.} a3 47. d4 $1 {And this is why I wanted my queen on a5!} Qc4
48. Qe2 $2 {Exchanging the queens won't blunt this pressure and removes any
chances White has of saving the game.} Bxd4 49. Qxc4 Rxc4 50. Ra2 {50. Rxa3 c2
followed by 51. ...Bb2 isn't really any better. The rest is just mop-up.} c2
