Posted as requested. I have not changed one word just corrected a spelling mistake if I caught one.
It's fairly easy to post a PGN just remember if posting a PGN in a new thread then look at it first in an old thread (with preview before post) you cannot preview a PGN in the first post, for some reason the system won't allow it.
Take or leave it comments.
The notes seem are good, the one after move 21 is a tad long as the user has to use the scroll bar to read it. I know there are scripts out there so you don't have to scroll but not everyone uses them. (try to write for the weakest player and users with out of date naff kit.)
Also good practise to keep your notes short and sharp. The longer the note then more chance of confusion or an error.
The Game:
Don't hob-nob with the GM's before a game. 😉
You appear not to have been phased by who you were playing which is good.
I would have played on to be shown, though it does look grim when it's a GM on the other side of the board. However he may have tried a trick playing on your TT (aggressive players are often impatient players).
I would not have played that Rb1 move (I never defend b-pawns, I have principles.) 🙂
I would have hit the twist-or-bust trail and played 14.Nd5 and if he wants the b-pawn.
14. Nd5 Nxf3+ 15. Rxf3 Bxb2 then 16. Raf1
I'm thinking of moves like Rf6/Nf6+/h4 and a double whack on g5 not to mention c3. Yup I could have fun with that position and as I'm a pawn down I am justified and fully committed to attack because the ending is lost (as always).
And you are right 23.Qd5+ was better. Well it looks better with hindsight.
Bebop5 - GM Manuel Leon Hoyos US Open 2013
Going into the tournament my opponent was the highest rated player entered at 2668 (USCF).
As I sat down at Board 1 the player next to me was GM Alex Lenderman. My opponent had not yet arrived so Alex asked me what I intended to play.
I replied that I usually essay the Catalan against stonger opponents.
He then cautioned me that GM Hoyos was a very strong tactical player and liked to play the Benoni or Benko Gambit.
I thanked him for his advice and told him that I liked his games. He seemed mildly pleased by the compliment.
I had entered the 4-day schedule so this game was played at a Game/60 time control.
Not the smartest thing for me to do as I had played fewer than 10 OTB games during the last year but that was the only way I could fit the tournament into my work schedule.

PGN
1. Nf3 c5 2. g3 g6 3. Bg2 Bg7 4. O-O {Intentionally delaying d4 so as to goad him into occupying d5 with his pawn and then try to transpose into a Reverse Gruenfeld. He doesn't bite.} 4... Nc6 5. e4 {I can't wait any longer and d4 plays into his familiar openings, so I move into a KIA.} 5... d6 6. d3 e5 7. Nc3 Nge7 8. Nh4 {A little premature but I want to beat him to the f-pawn push.} 8... O-O 9. f4 exf4 10. Bxf4 h6 {creating a K-side weakness but gaining a tempo as I must retreat a minor piece.} 11. Be3 Nd4 12. Qd2 {fixing his pawns or forcing his King to move.} 12... g5 13. Nf3 Nec6 {strengthening his grip on d4} 14. Rab1 {planning to oppose his knights by Ne2 and then trading pieces, eventually he will have to either trade his dark square Bishop or have doubled d-pawns. In itself that is not weak as then my c-pawn becomes a target. However it would take time and preparation to attack it. In the meantime I was hoping to be able to pry open the Kingside.} 14... f5 {perhaps not strongest as there is are holes at d5 and e6 that I must try to exploit.} 15. Nd5 fxe4 {Creating an isolated pawn and three pawn islands. Good position play at cost of relieving tension in center.} 16. dxe4 Nxf3+ {Surprising, I thought he would force me to trade.} 17. Rxf3 {In order to exchange Rook and Bishop without leaving b-pawn loose.} 17... Rxf3 18. Bxf3 Bh3 19. Bg2 Bxg2 20. Kxg2 {After the game GM Hoyos suggested that Qg2 was better. I agreed as it kept my Knig off the same color as isolated e-pawn and protected it as well. However I wanted to not lose time being able to transfer my Queen to d5, c4 or b5.} 20... Qe8 21. Qd3 Qe5 {Here time was almost equal, I had 26 remaining and my opponent 28. I spent 7 minutes here trying to calculate what happens after b4. My intuition told me that it was correct; hitting his c-pawn, opening a file for my rook and eliminating a weak pawn of my own that required protection. Nevertheless I faltered and played what I thought would enable me get rid of his Bishop. However I didn't look far enough to realize that his Knight ends up stronger than my Bishop.} 22. Nc7 Rc8 23. Qc4+ {Imperative is Qd5+, giving me time to defend the e-pawn.} 23... Kh7 24. Ne6 Re8 25. Nxg7 Kxg7 26. Rd1 {Under time pressure here I didn't see that he gets back in time to defend d-pawn. My 10 minutes to his 22. Best is Qc3 trading Queens and giving some hope of holding} 26... Qxe4+ 27. Qxe4 Rxe4 28. Kf3 Re6 {Some may think that it was a bit early to resign, but down a clear pawn and with only a few minutes remaining I thought it respectful to concede considering his rank.}
