...who is not at all easy to win against.

All the photos used in this report are by John Brezina. The heading photo is Sullivan McConnell, maybe showing Mr. Colorado Chess, Brian Wall, that he is already completely winning :-) I went mostly retro with the pictures within the text, just because black and white photography is rarely seen anymore. Note that the photos are not necessarily related to the text. See all of Mr. Brezina's photos.    I should mention that Mr. Brezina was only able to get to the tournament late in the last round. Thus, no room shots.

The 2025 DCC Denver Open registration of 141 players was certainly not bad, but somewhat short of the average of 185 players at the three previous DCC Denver Open tournaments. Anyway, this year in the Championship section, Sullivan McConnell, with 4.5 points, took 1st place and won - are you ready for this - 1200 dollars!! Which I think is the highest DCC tournament prize ever. I'm sure that if Sullivan had not been paired against his brother, Griffin, in Round 4, his score would have been 5-0.  

Griffin McConnell, figuring things out. 

Suhaas Narayanan and Sikander Baker-Nagar ended up with 4 points, and they share the combined 2nd and 3rd place prize of 1250 dollars. There was a four way tie for the 4th place prize. Brian Wall, Rhett Langseth, Daniel Herman, and Christopher Motley each won 80 dollars. Mr. Motley (2001) had the pleasure of upsetting both Eamon Montgomery (2259 ) and Griffin McConnell (2223). See Chris Peterson's Best Game below.

Quite a range of ages in this picture.

With 3 points, Caleb Koeller, Jason Nigatu, Forrest Lundstrom, and Kaavya Sakthisaravanan share the U2000 Prize of 240 dollars. Kaavya had a full point 1st round bye, lost her Round 2 game, then upset her next three much higher rated opponents to earn her share of the prize money. The 80 dollar Championship section Upset Prize went to Leif McFadden (1742) when he took the full point from the potential Candidate Master, Rhett Langseth (2135) in Round 2.   

In the U2000 section, Sean Pearson took no prisoners and won the 1st place prize of 480 dollars with a perfect 5-0 score. Candidate Master, Mike Maloney, only lost to Mr. Pearson, and he won the 320 dollar 2nd place prize. Ethan Crane, Khris Mathimaran, Logan Stewmon, and Rohan David all finished with 3 points and they each won 80 dollars. In addition, Mr. David (1585) also won the U2000 80 dollar Upset Prize for his win against Jeremy Roldan (1886) in Round 2. 

I got this. The rest is going to be easy.

In the U1700 section, Scott Marvel and Ashwin Mathimaran each finished with 4.5 points, and they share the combined 1st and 2nd place prize of 720 dollars. Colin Schaub (1287) won the 3rd place prize of 180 dollars in addition to winning the 80 dollar Upset Prize for his Round 2 win against Nii Codjoe (1615) The 4th place prize was won by Jack Gottlieb, Anthony Cordova, Philip Schiff, Trever Bradford, and Dustin Ferguson. They all finished with 3.5 points, and each player won 20 dollars.

Emma Hellmer (b) vs. Madeleine Finch (w). More women in chess would be a good thing. 

In the U1400 section, Unrated Emma Hellmer took 1st place with 4 wins and a Round 2 draw. But being Unrated, only qualified to win 250 dollars instead of 400. The extra I50 dollars was added to the Tarun Karthikeyan and Quinsen Joel prize. They each won 4 games, and instead of winning 200 dollars each, they both took home 275 dollars. Viaan Khandelwal ended up in 4th place with 3.5 points, and that was worth 80 dollars. Jinhyun Shin (920) won the 80 dollar Upset Prize for his Round 1 win over Madeleine Finch (1301), who is not at all easy to win against.

This player has just hit the clock and, too late, maybe thinking, uh-oh :-)

In the U1100 section Eric Zhang, Ryan Gupta, and Robert Downes all scored 4 points, and they each won 266 dollars and 67 cents. Liam Newell and Jacob Just ended up with 3.5 points, and they each won 40 dollars. Anirudh Saibalan (848) won the 80 dollar U1100 Upset Prize when he won his game against Mr. Downes (1036) in Round 1.

Total concentration.

DCC President Earle Wikle and I don't always see eye to eye, but I sure cannot gripe about his prize fund money distribution. It's as fair as fair can be, with as many winners as possible. 7290 dollars was shared by 39 winners!! Who has ever heard of rewarding 4th place? Not to mention that having five sections means that, regardless of a player's rating, they have a chance to win prize money. Plus, adding an 80 dollar Upset Prize for each section is great. Not only does the player win USCF rating points, and bragging rights, but they also win bonus money to spend. In addition, Mr. Wikle sets up the DGT  boards at DCC tournaments.  

I've said that I was going to quit writing these DCC reports, but a couple of people, whom I regard highly, have encouraged me to continue. So I will, even though I'm old and tired - but still good looking :-) Besides, what else do I have to do?  I am truly grateful to the thousands, ok hundreds, of chess players who read these DCC reports regularly. 

Best Game

by NM Christofer Peterson

There were a lot of great games played at the 2025 Denver Open, and picking just one to write about wasn’t easy. I want to give a quick shoutout to Mike Maloney, who had two excellent games I seriously considered covering. Brian Wall, as always, played entertaining, chaotic chess — his games were also in contention.

But ultimately, I decided on the game between NM Eamon Montgomery and Christopher Motley. Eamon had a tough tournament, and Christopher had a great one. There’s always something interesting about a matchup where a higher-rated player is struggling and the lower-rated player is in form. As someone who’s often near the top of the seed list in tournaments I’ve played, I know what kind of pressure that creates. When you’re rated ~300 points higher, everyone expects you to win. If you do, no one says anything. If you don’t, it becomes a spectacle.

So I’m not highlighting this game just because a lower-rated player won — though that’s always fun to see — but because of the clean, principled play Christopher showed throughout. His opening was sharp, his middlegame plans were clear, and he played with confidence. It was a really nice game. As for Eamon, everyone has an off tournament now and then, and I don’t think anyone doubts he’ll be back in form soon.

1. d4I've talked about Eamon before. He's a dangerous opponent — solid, principled, and rooted in strong positional and strategic play. While he tends to shy away from wild tactics, he's shown many times that he can calculate with the best of them. 1... d5Christopher Motley is an interesting player. He knows his openings very well and often gets strong positions right out of the gate. I've been on the wrong end of his prep before. That said, games against stronger players sometimes slip away — often in heartbreaking fashion. In one of our games, for example, he got a crushing advantage out of the opening, but I managed to trick him into trapping his queen. If he can patch whatever is going wrong in the middlegame, he'll be a very tough player to deal with. I/ ^m curious to see how he handles Eamon, who plays it safe early on. Let's see if he can put his motley band of pieces to good use. 2. c4 e6 3. Nc3 c6 4. e3 Nf6 5. Nf3 Bd6 6. Bd3 O-O 7. O-O dxc4 8. Bxc4 b5 9. Bd3 Nbd7 10. Qc2 Bb7The Chigorin variation of the Semi-Slav has been played at the highest levels. Compared to many other defenses to the Queen's Gambit, it scores well. While it's fallen a bit out of fashion due to its drawish tendencies, players like Aronian, Firouzja, Giri, and even Carlsen still bring it out. 11. a4?!It's natural for White to strike at the queenside, and the a4 break is thematic in many lines. But here, it plays into Black's hands. Without a c-pawn, White can't challenge b4 — which Black can now claim with tempo. This line exists in databases, but Black has a very strong record thanks to how easy it is to play.( 11. a3A more modest approach to blunt Black's expansion and keep the position rich. )( 11. Ng5 h6 12. Nge4Eljanov played this way, aiming to trade down quickly for a draw. )( 11. Rd1Carlsen's choice in another game. ) 11... b4 12. Ne4 Nxe4 13. Bxe4 f5 14. Bd3 c5!The light-squared bishop is now active, White's center is coming under pressure, and c4 is looming. 15. Qe2( 15. dxc5??The tactics are a little messy but bear with me. 15... Bxf3 16. cxd6( 16. gxf3 Bxh2+!! 17. Kh1( 17. Kxh2 Qh4+ 18. Kg2 Qg5+ 19. Kh1 Rf6mate is coming ) 17... Qh4Black wins easily. ) 16... Rc8( 16... Qg5 17. g3 Ne5 18. Be2 Qh5 19. Bxf3 Nxf3+ 20. Kg2 f4!! 21. exf4 Qd5! 22. Rd1 Nd4+ 23. Kg1 Nxc2 24. Rxd5 exd5Black is up a rook. ) 17. Qb3( 17. Qb1 Qg5 18. g3 Qh5 19. h4 Ne5 20. Bd2 Qg4 21. Kh2 g5White's king is in trouble and material must be sacrificed to survive. ) 17... Nc5 18. Qc4 Bd5 19. Qd4 Nxd3 20. Qxd3 Bc4 21. Qd4 Bxf1 22. Kxf1White is underdeveloped, the king is exposed, and Black is up the exchange. ) 15... Qc7( 15... Qe7Would've kept the queen tucked safely away from coming c-file fireworks. ) 16. h3?!( 16. b3White must stop c4. It's not ideal, but it dulls the bite. ) 16... Bxf3 17. Qxf3( 17. gxf3 Rf6 18. Bd2 Raf8 19. Bb5 Qd8Black is infiltrating. White will struggle to find a coherent defense. ) 17... c4 18. Bc2?It makes some sense to keep e2 open for the queen, but there was no danger of getting trapped. Be2 would've saved a tempo. Perhaps Eamon hoped to provoke b3 and block c3 — but he's too far behind in development. 18... b3 19. Bd1 Nf6 20. Bd2 Ne4 21. Be1 Rab8 22. Rc1 Rfc8 23. Be2Despite Black's pressure, the engine gives White a slight edge again. With near-perfect play, White might slip out of the bind. 23... c3 24. Bxc3 Qf7( 24... Qd8This keeps the queen active on both wings. Centralizing the queen is a key strategic idea. From f7, her access is more limited. ) 25. Ba6( 25. Bb5A useful defensive try. It cuts coordination and might allow Qd1-b3 later to pick off b3. ) 25... Rxc3!A nice positional exchange sac. It doesn't win by force but keeps White tied up. Instead of improving his pieces, White has to keep defending. 26. bxc3 b2 27. Rce1 Nxc3( 27... Qc7Let's get the queen involved. Nd2 is a constant threat, so there's no rush. Simplifying with ...Nxc3 makes White's job easier. 28. Bd3 Nd2 29. Qe2 Qxc3 30. Bb1White is completely bottled up. 30... g6 31. Qa6 Qc7 32. Rd1 Nxf1 33. Rxf1 Kg7Black can now steadily improve and dominate along the c-file. ) 28. Qc6??( 28. Bd3White had to turtle up and play for counterplay later. Trading queens helps Black's bind. ) 28... Qc7 29. Qxc7 Bxc7 30. Bd3 Nxa4 31. Bb1 Nc3A picturesque bind. The a-pawn now rolls freely. 32. f4 a5 33. Rf2 a4 34. Bd3 a3 35. Bc4 b1=Q( 35... Kf7 36. g4 b1=Q 37. Rxb1 Rxb1+ 38. Kg2 Rb4 39. Bd3 Nd1 40. Re2 Rb3 41. Ba6 Nxe3+ 42. Kf2 Bxf4Total collapse. ) 36. Bxe6+ Kf8 37. Rxb1 Rxb1+ 38. Kh2 Rb2( 38... Re1Let the stew simmer. White's collapse is inevitable and Black can extract more material. 39. d5 a2 40. Rxa2 Nxa2Black is up a full rook and piece. ) 39. Rxb2 axb2 40. Bxf5 b1=Q 41. Bxb1 Nxb1Black is up two pieces for three pawns. Maybe White can hope for a knight-and-bishop checkmate scenario, but even that is unlikely — maintaining one pawn will be easy. 42. Kg3 Nc3 43. Kf3 Bb6 44. f5 Ke7 45. g4 Kf6 46. Kf4 h6 47. h4 Bc7+ 48. Kf3 h5 49. gxh5 Kxf5 50. d5 Ne4 51. h6 gxh6And White threw in the towel here. A very nice game by Christopher Motley. He really showed how positional exchange sacrifices can establish a bind, then converted with solid endgame technique. This game is a great reminder that material is only part of the story — positional understanding can trump it.0-1

Congratulations to Christopher Motley on an excellent game and a strong tournament performance. If your rating had been just two points lower, you would have earned quite a bit more prize money — one of the quirks of using the latest US Chess supplement instead of live ratings. Either way, this game was a standout, and I hope we get to see more like it from you in future events.

Quick Note on the Monthly Write-Ups

I also want to apologize for not doing write-ups for the last couple of DCC Monthlies. As some of you know, I’m in medical school, and we just wrapped up our final preclinical semester. It’s been a lot. For context, most college students take around 12–16 credit hours per semester. Medical students do 25–30, and the material is way more intense. Now that we’re done with preclinicals, I’m heading off to Minot, North Dakota to start my clinical rotations at Trinity Health Hospital. I’ll be learning on the job and getting a real sense of what it takes to be a doctor.

I’m hoping to keep these write-ups going when I can, but school has to come first. Thanks for your patience — and keep sending in your best games.

Thank you, kindly Chris. Your instructional analysis of the Best Game benefits the players in addition to everyone who plays through the game.

Thanks again to all, 

J.C. MacNeil
