 | | Fusilli: OK, US Senior Open is over.
Round 1: Chibana (1504) vs Sana (2131), 0-1
Round 2: Sana (2131) vs Moore (1800), 1-0
Round 3: FM Eckert (2217) vs Sana (2131), draw
Round 4: Sana (2131) vs FM Resika (2200), draw
Round 5: Sana (2131) vs Vollmer (1928), 1-0
Round 6: GM Kraai (2452) vs Sana (2131), 1-0
I just submitted all but the first game. They are interesting. The game vs FM Eckert was intense! Unfortunately, I played carelessly vs GM Kraai and was swiftly punished. Sana vs Vollmer, white to play.

 | | FSR: <Fusilli> Excellent showing despite the last-round loss to Kraai. Not easy playing black against a GM. I'm guessing it still wins you a little money. I heard that Kraai, Mitkov, Eckert (!), Fishbein, and I think one other tied for first, with Kraai winning on tiebreak, which means that he qualifies for the U.S. Senior Closed next year. I played in last year's U.S. Senior Open, where I felt sad for Kraai. He won his first five games (including against fellow GMs Yermo and Fishbein), but lost to Dmitri Gurevich in the last round to finish second. He was the only player to face three GMs, and scored 2-1 against them, but it wasn't enough to win the tournament. Gurevich's one draw was a quickie against Fishbein. |

 | | Fusilli: <FSR> I am a bit bummed by how badly I played against Kraai. Even though I was obviously the underdog by a large margin, it was my worst quality game of the tournament. One could assume I was intimidated, but I really didn't feel (or even feel) that way. I think it was the opposite. I played overconfident, probably buoyed by the good tournament I had and my strong play up to then. The game against Kraai was the only one where I blundered badly. To wit, consider the game accuracy scores computed by chess.com below. "Game accuracy" is a measurement of how closely you played to what the computer has determined to be the best possible play against your opponent's specific moves. I added game accuracy at the end of each result. R1: Chibana vs Sana, 0-1 (80.3 vs 96.3) (Gap: -16.0) R2: Sana vs Moore, 1-0 (90.3 vs 85.5) (Gap: +4.8) R3: FM Eckert vs Sana, draw (92.8 vs 92.9) (Gap: -0.1) R4: Sana vs FM Resika, draw (98.0 vs 98.2) (Gap: -0.2) R5: Sana vs Vollmer, 1-0 (90.4 vs 76.6) (Gap: +13.8) R6: GM Kraai vs Sana, 1-0 (97.0 vs 84.3) (Gap: +12.7) The absolute score depends on how complex the position was. A score of 90 in one game does not mean you played better than a score of 85 in a more complex game. What matters most is the gap. The nearly zero gaps vs Eckert and Resika show we were quite even. Now, the gap with Kraai is huge, owed in part to that bad blunder. But compare to my last two losses vs grandmasters: M Sana vs F Corrales Jimenez, 2022, 0-1 (77.8 vs 85.8) (Gap: -8.0) Benjamin vs M Sana, 2019, 1-0 (85.7 vs 82.0) (Gap: +3.7) Both Corrales-Jimenez and Benjamin had to think to beat me. Kraai used about 15 minutes for the whole game because I made it so easy for him, right out of the opening. But again, you are right I had a strong tournament and played well, so I can't complain. Next time I play a GM, I'll try not to waste the opportunity so easily. |

 | | FSR: <Fusilli> That's a drag, although at our level playing well in five out of six games is pretty good. But yeah, you'd like to at least make the GM work for the point. How do you get an accuracy score on chess.com for a game you played elsewhere? I didn't know that was possible. |
|
Jul-24-23 | | Unstable Psychopath: <Fusilli> Would it have helped you play better if someone offered to buy you a three year CG membership if you beat the GM? |
|
Jul-25-23
 | | Fusilli: <FSR: How do you get an accuracy score on chess.com for a game you played elsewhere? I didn't know that was possible.> In the chess.com main menu, go to Learn, then to Analysis. In the box on the right panel, paste the pgn of the game/s you want. Then click on the green button "Add games." It will load the game for analysis. Click on the Review button, to the right of Analysis. That's it! I just did it for your game with Yermo. It gives you 98.4, and 98.6 to Yermo. |

 | | Fusilli: <Unstable> Not at all. |
|
Jul-25-23
 | | FSR: Here is the crosstable: https://www.uschess.org/msa/XtblMai.... Kinda crazy - six players scored 5-1 to tie for first: GMs Kraai (winner on tiebreak), Mitkov, and Fishbein; FM Eckert; and NMs Peter Gilruth and Steve Szpisjak. GMs Yermolinsky (4.5) and Kudrin (4) didn't make it. |
|
Jul-25-23
 | | Fusilli: <FSR> True. With 79 players and six rounds, it can happen. Here's the organizer's version of the crosstable, which includes the detailed tie breaks: https://www.kingregistration.com/re... So, technically, I played the top two players. And I shared 13th place with Kudrin. Feeling good about this. I don't know if Yermolinsky and Kudrin had a GM draw in round 4, but I guess they'll both think it twice next time, as they both lost in round 5. Kudrin left after that. Respect for Yermo, who stayed for game 6 (and won). GMs in open tournaments sometimes quit when disappointed. |
|
Jul-25-23
 | | FSR: <Fusilli> Last year, Yermo drew me in Round 5, then withdrew. I guess his ego could survive a loss to Eckert, but not a draw against me. |
|
Jul-28-23
 | | Fusilli: Starting the 5-round Nashville Summer Classic today (https://ncc.clubexpress.com/content...). At the moment, we are only 16 players in the top section, and I am ranked 9th. Which means I'd play the top rated player, Alexander Fishbein. That's fine, better to play a GM when I am rested! Still time for other people to join, which would alter the pairings though. (Of course, if new players are higher rated than me, I'm still playing someone strong.) |
|
Jul-28-23
 | | FSR: <Fusilli> Good luck! |
|
Jul-29-23
 | | moronovich: Good luck !, <Fusilli> ! |
|
Jul-29-23
 | | Fusilli: <FSR> <Moro> Thank you guys. I lost to Fishbein last night, but I put up a decent fight. I will submit the game after the tournament is over. <FSR> How's Grand Rapids going? |
|
Jul-30-23
 | | FSR: <Fusilli> Played IM Nikoloz Managadze. Typical game where higher-rated player plays King's Indian against lower-rated player. I was better for the first 22 moves, didn't play energetically enough (needed to break with f4), still could have been equal, didn't, got smashed by his kingside attack. Live and learn. |
|
Jul-30-23
 | | Fusilli: <FSR> Indeed, my friend. Today I won the first game and drew the second one. Intense games. I will submit them after the tournament. |

 | | Fusilli: Quite a dramatic finale in my third-round game yesterday. Decord vs Sana, position after 30...Qb7-c7
 click for larger view30...Qb4, and I was able to save this! He had to move the h-pawn here (31.h4 gives +0.58 and 31.h3 gives +0.40). He played 30.d6:  click for larger view30...Qd4+ 31.Kh1 Rxb2
 click for larger viewThe rest to be posted with the game (<CG> willing), after the tourney is over. Draw in 40. |

 | | Fusilli: Done with Nashville Summer Classic. +2 =2 -1
I am submitting the games for uploading.
Something interesting from round 4:
Sana vs Caveny
In the position below, the computer says I should have played 12.O-O-O (+1.90)  click for larger viewI played 12.Bf6, which the computer calls a blunder (??).  click for larger viewBlack to play and equalize. Difficult!
(He missed it. 1-0 in 28.) |

Jul-31-23
 | | chancho: 12...Bb4 and if white plays 13.Bxf8, then black goes Bxc3+ 14.bxc3 Qxc3+ |
|
Jul-31-23
 | | Fusilli: <Check it out> That is the variation that happened in the game, which was posted today:
M Sana vs Aaron Caveny, 2023 <Chancho> That is reasonable, and against 12...Bb4, I was planning to play 13.O-O. White keeps a sizable positional advantage. The saving move is the amazing 12...Ba3!!
 click for larger viewThe problem is that if 13.O-O Bxb2 14.Rab1 Bxc3 15.Bxh8 meets 15...d5!  click for larger view And the capture en passant reveals a hanging white bishop on h8. Ouch. So, the computer recommends 13.O-O-O, and after 13...Qxc3 14.bxa3 Qxa3+ black has a draw.  click for larger view(15.Kd2 d5 here is dangerous for white, and after 15.Kb1, white can't play Bb3 against Qb4+ because of the hanging queen on e4.) |
