I am sure glad to be able to start off one of these reports without complaining about attendance. We optimistically based our 4000 dollar prize fund on a registration of 125 players, thinking we would do well to get 100. I am pleased to report that we drew 122 participants.

This in spite of another Colorado spring snow storm starting late Friday night, and lasting the whole weekend. Two feet of heavy wet snow in places, and a cold north wind blowing all day and night. Spring time in the Rocky mountain area. Ya gotta love it :-) We had 6 preregistered players withdraw due to the storm, and I am sure there would have been at least 10-15 more walk up players the day of the tournament, if there had not been a winter storm in April. Still, with 122 players the DCC was happy to pay out the full 4000 dollars in prize money. In addition Ann Davies donated 200 dollars for a Cassia Women's prize, plus a 10% entry fee discount for all woman players. Thank you very much, Ann. You are so cool :-)

More than half of the 41 players in the Open section were rated over 1900, and of course it was further strengthened with the presence of WIM Mariam Danelia. I think anyone would have considered it a safe bet to say the WIM would take the 1st place prize money and leave the other prizes for the local players. Well that was not the case. Newly minted USCF master, Chris Peterson has taken his game to the next level and showed that his 2200 plus rating is no fluke. Chris allowed one draw to Gunnar Anderson and won all his other games. Impressive was all of his games were less than 40 moves, with three of them being less than 30 moves. Whack. Smack. Take that 700 dollar 1st place check to the bank.


A few moves before clear first place was decided

His last round game against Akshat Jain is a classic, and should be played over by anyone who wants to see a beautiful game. Chris said there is an old Russian adage that 3 pieces is a mate. In this game you see the proof of that. But I hear you saying Akshat is only rated 1827, so of course Chris won. Ask yourself how a 1827 rated player can be playing on board 1 in the last round. Really, these two players are the story of the tournament. Prior to running into the Peterson buzz saw, Mr. Jain had upset Rhett Langseth (2106), Kevin Seidler (2141), Lior Lapid (2290) and then drew WIM Danelia (2363) That is a stunning string of games and Akshat's rating will jump to 1970 in one go. Whooowee baby, that is some good chess. it is a shame that Akshat's 3.5 points only won the U1950 prize of 100 dollars.

1. Nf3Ryan Polsky is a student at CSU. He braved the blizzard conditions on I-25 to play in the tournament. I do not know a lot about him or is play style other than he beat Brian in a blitz game at the Wild Boar not too long ago. 1... Nf6 2. g3 b6 3. Bg2 Bb7 4. O-O e6 5. d4 Be7 6. b3My anti-theory opening. I just try to avoid everyone's preparations by playing the double fianchetto system. It has the benefit of avoiding trades, being solid yet dynamic enough to explode at a moment's notice. The downside is it is somewhat passive so without accurate play white can easily find himself in a bad position. 6... O-O 7. Bb2 c5 8. c4 d5( 8... cxd4 9. Qxd4 Nc6 10. Qf4 d5 11. Rd1 Qb8 12. Qxb8 Raxb8 13. Nbd2Queenless middle games are some of the most complicated things to play, just look at the Berlin. I would risk being able to outplay an A-player in this position. ) 9. e3In positions like this a lot of times the first person to release the tension in the center gets the worst of it. "To take is a mistake" is a well known grandmaster adage. 9... dxc4 10. bxc4 cxd4 11. exd4This is known as a hanging pawn position. It is ideal for attacking players because it is extremely dynamic. White's goal here is to open lines and play for a king-side attack. For black he wants to force an advanced and blockade on the holes. Once the pawns are blockaded, they become weaknesses. 11... Qc7 12. Qe2 Nc6 13. Nbd2 Rfd8 14. Rac1 Rac8 15. Rfe1 Ba6The hanging pawn structure may look weak but its flexibility and mobility make it excellent at parry and riposte.( 15... Bb4Is a more compelling try, attempting to undermine the defenses prior to attacking the pawns. 16. Red1 Na5 17. d5 exd5 18. cxd5 Qe7 19. Qxe7 Bxe7 20. Rxc8 Rxc8 21. Bxf6 Bxf6 22. Ne4White has a passed pawn but it will not be easy to advance while black has the two bishops. ) 16. Nb3 Bb4 17. Red1 Na5?The fruition of a bad plan. Black is now left with a useless bishop or b4 or a dead lost queenside position. 18. Nxa5I generally advocate for avoiding trades or at least not being the first one to capture. Here, however, it either irreparably damages black's pawn structure or forces black's bishop to the worst square possible. 18... Bxa5 19. Ne5A dominating square for a knight to occupy. With the hanging pawns about to advance, black is starting to get into serious trouble. 19... Bb7 20. d5!White's advantage is starting to become tangible. 20... exd5?Trading only hurts black's position. The position is getting more open which making white's two bishops stronger and stronger. 21. cxd5 Qd6?I was expecting Qe7 pinning the knight. It makes sense why he did not play it because the move d6 is scary.( 21... Qe7 22. Rxc8 Bxc8( 22... Rxc8?? 23. d6Winning a piece. ) 23. Qc2 ) 22. Rxc8?!Missing more direct wins.( 22. Nc4I had this option but I love my bishops too much. 22... Qf8 23. Bxf6 gxf6 24. Nxa5 bxa5 25. Rb1 )( 22. Nc6The immediate Nc6 is crushing. Black is struggling to find any moves. 22... Re8 23. Qf3 Bxc6 24. dxc6 Qe6 25. c7Taking a quick stock of this position makes it clear white is much better. Two bishops, dangerous passed pawn on c7 meanwhile black has a crippled a5 bishop. ) 22... Rxc8 23. Nc6 Bxc6?Not a lot can be said about this move. It seems Ryan was in the mood to trade as many pieces as possible. Unfortunately his choice of trades just compounded the weaknesses in his position. 24. dxc6 Qe6 25. Qb5( 25. Qxe6While trading queens is winning too, it is usually best not to play into what your opponent wants. ) 25... h6( 25... Qxa2??A not so subtle trap 26. c7 ) 26. h3 Rc7??This move loses quickly but it is difficult to suggest a move for black. His entire queenside is immobilized. If he moves anything on the kingside he is opening himself up to mating attacks down the long diagonal.( 26... Qxa2??Another not so subtle trap 27. c7 ) 27. Rd8+ Kh7 28. Qd3+ g6 29. Qe3Everything is winning here. I just wanted to play the simplest win.( 29. Qa3 Re7 30. c7 Re8 31. c8=Q )( 29. Qd4 Kg7 30. Rd6 )( 29. Qe4I should have played this for the aesthetics. ) 29... Qxe3 30. fxe3 Ng8 31. Be5White wins1-0

From what I saw, none of WIM Danelia's games were easy for her. She allowed a draw to Zhiji Li in round 3, and as mentioned, to Mr. Jain in round 4. In the last round, Gunnar Anderson pushed hard and the consensus was he was better. Mariam was calm and cool under pressure and turned the tables. Eventually mating Gunnar's King on the side on the board. When the smoke cleared we had 5 players tied for 2nd place with 4 points.

In addition to Mariam, the other players to finish with 4 points were: Kevin Seidler, Zhiji LI, Morgan Robb, and Ryan Swerdlin. All these players had excellent games. I know Kevin was especially pleased to win his last round game over none other than Brian Wall. Mr. Li played a sweet trick to queen a passed pawn and win his 5th round game over Daoud Zupa. With ice in his veins Zhiji was playing the last like 20 moves on the increment.


The up and comings showing their presence

Morgan's rating is going to take a big jump, with an upset win over Mr. Lapid and drawing Mr. Wall with outstanding play. Ryan won his share of the prize money with a last round win over the long time Colorado player, Brad Lundstrom. Mr. Swerdlin won all his games except for a round 2 loss to Mr. Zupa. Congratulations to all of these players. It seems such good chess should win more than 140 dollars each.

Between rounds, it was interesting to listen to Mr. Lundstrom and Earle Wikle talk about chess history, players, famous matches, and different opening lines. I thought only Grandmasters could discuss opening lines or games from memory without a board or pieces, but these two guys can do it just as well. "In the Fischer line of the London system, what do you play after Nc6?" and off they would go. Was a trip to me. Both have extensive chess book collections that they actually read and study. The human mind and memory is endlessly fascinating.


Tournament in full swing!

The story of the U1800 section was Francisco Torres, an unrated player, winning all his games except for a last round draw with Ann Davies. 4.5 points was only worth 150 dollars due to the prize money restriction on unrated players playing in the Under sections. Mr. Torres knew this coming in and had no complaint. We are hoping to see Francisco and his two children, Franz and Frances Janelle, on Tuesday nights at the DCC.

This left the 1st, 2nd, and 3rd place prizes to be shared by; George Voorhis, Jose Magno, and Ann Davies. They all ended up with 4 points and each won 317 dollars. George won his last round game over long time DCC member, Vibi Varghese. Jose won against Calvin DeJong. Calvin is, i think, around 10 years old (I'm guessing) He played in the Friday night simul and won his round 4 game against yours truly. So I was hoping he would go on and win his last round game, but he did not. Ann played very well in her 1st round game. In severe time pressure, essentially playing on the delay, Ms. Davies beat the strong Steve Kovach.

Ann also ended up the best women best women's score which added 125 dollars to her prize winnings. Deanna Alter had the 2nd best women's score and won 75 dollars. I was playing on the board next to Deanna in round 5. While I was trading pieces to a boring opposite Bishop ending, Deanna was playing a great king side attack. She sacrificed a Knight,put a pawn on g6 and left the black King with nowhere to run. Another young lady who played good chess was Teah Williams. Her brothers, Josh and Jessie and her sister Selah, played in the Under sections, but Teah was nervy enough to play up to the Open section. She upset Gerry Morris and drew against Jack Woehr, who are both strong experienced players. Teah will gain a whopping 55 rating points. Congratulations ladies. We would like to see you at all our tournaments.

The U1700 prize was shared by Cory Kohler and John Byrne. They each finished with 3.5 points and won 50 dollars each. New to the DCC, Michel Doyon, and the above mentioned Calvin DeJong shared the U1600 prize and they also won 50 dollars each with 3 point scores. Congratulations to all of you, and you are all invited to join Mr. Doyon at the DCC on Tuesday nights.


Best attendance at a Denver Open ever!!

In the U1500 section, 1st and 2nd place was shared by Peer Seyferman and Ryan Thompson. They played very well to finish with 4.5 points and win 375 dollars each. Why can't I play like these guys :-) The 3rd place prize was split between Todd Burge and Jesse Mellinger. Each scored 4 points and each won 125 dollars. Issac Bean, an unrated player, also finished with a 4 point score and won the restricted prize of 100 dollars. Restricting unrated players like this doesn't seem fair, but it is to prevent maybe a strong internet player, or a street hustler from taking place prize money from USCF rated players. Unrated players can of course win any place prize in the Open section.

I am happy to report that hardworking DCC member and Tuesday night regular, Rob Cernich, won the U1200 prize of 100 dollars. We would very much like the other U1500 winners to join Rob on Tuesday nights at the DCC. Have I mentioned playing at the DCC on Tuesday nights elsewhere in this report? :-)

To wrap up this report, i would like to give credit to the TD's, Todd Bardwick and Dean Clow. Todd is a long time Colorado scholastic tournament TD, and Dean has really improved the Tuesday night registration process. His "Caissia" pairing system faced a real test here at the Denver Open and I believe passed with flying colors. Todd and Dean got the 1st round started on time for maybe the first time ever at a Colorado tournament. Todd and Dean handled one dispute after another in the 3rd round of this tournament. All were settled professionally and the players involved accepted the TD's rulings without too much complaint. Thank you very much gentlemen. Players and TD's alike.


The DCC treasurer learning from the best.

Finally, I would like to thank Whole Foods for providing a free of charge coffee service on Saturday. Starbucks did the same on Sunday. I am a coffee drinker and I certainly appreciated this service, as did many others. The Embassy Suites Hotel provided everything we asked for, and despite the ongoing construction, the playing room was quiet. The simul and the tournament would not have happened without Randolph Schine making all the arrangements. High grade professional organization was what it was.

Thanks again to all, J.C. MacNeil
