Norway Chess Tournament 2018 and Poikovsky Karpov Tournament

There is a lot to watch for in the Norway Chess Tournament. Carlsen and Caruana are both playing, giving us a preview of their upcoming match. Anand finds himself in the unfamiliar position of being the bottom seed. Will he return to the top 10?



The Poikovsky Karpov tournament features a strong field with 5 members of the 2700 club. Gelfand no longer belongs to that group - will he stage a comeback? Nepomniachtchi is occasionally found in the top 10 lists. It's not impossible for him to return, but he would have to score very well for that to happen in this tournament.

2018 Summer Classic

Another strong round robin in St. Louis. All 10 players in the A group are 2600+.



Methodology



E4stat vs. chess prodigy

Earlier this month, e4stat played in the 2nd Haymarket Memorial tournament in Chicago. In Round 1, I faced Yuvraj Chennareddy. You will probably hear a lot more about him in the future. He is currently America's top 7 year old chess player - his rating is already in the low 1800s! I don't think I saw his best chess that day. However, on the note to move 26, we catch a glimpse of his great potential. Here I try to explain all the little details that go into converting an extra Exchange.

Re1 {The move order has been altered in order to conceal one of e4stat's opening surprises :)} Nxd2 12. Qxd2 { I thought that I had no advantage here, but the computer still believes in my position. This recapture looks awkward, but it does keep an eye on ...d5-d4 and in a few moves, White's queen and bishop will untangle by using a typical idea.} Na5 13. Bc2 Nc4 14. Qd3 g6 15. b3 Nb6 (15... Na3 $5 {looks suspicious, but neither the computer nor I can find a way trap the piece. But the Black knight causes disruption, so I should have played 15.Nd4 (Stockfish's suggestion) instead of 15.b3.}) 16. Bh6 c5 $2 {After the game, I asked him why he didn't save the rook. He said he thought his queenside majority would offer enough compensation. But clearly Black doesn't have to sacrifice in order to push his queenside pawns.} 17. Bxf8 Bxf8 18. Qe3 $1 {I like this move. Black got a bishop for a rook, so let's make sure that the bishop never gets active.} Qc7 ({This is not a great square for the queen.

My idea was Bc2-d1-f3, transferring the bishop to a square where it would support g2-g4 and also hit d5. In addition, White can double rooks on the d-file. But this plan is too slow. Though my concept was wrong, the move is still okay because we will see later that the rook has some uses on the 2nd rank.} ({ After the game, I proposed} 25. b4 {, preventing the plan that Black starts on his next move.

White will gradually prepare h2-h3, g3-g4, and f4-f5 and there isn't much that Black can do about it. Objectively, it's not any better than what I did in the game, but this is a much easier path to victory.}) 25... a5 {Black intends ...b4 cxb4 ...axb4, creating a passed d-pawn.

Even though 26...h5 loses, he should have tried it since it would have required me to find some ideas that are difficult to see. After the move he played in the game, the hard part is over.}) 27. g4 (27. Bxf5 gxf5 28. g4 { was also appealing, but then Black would still have ...b5-b4 ideas}) 27... Bxc2 28.

In Round 2, a 2300 caught me with a weird tactic:

[Event "2nd Haymarket Memorial"] [Site "Chicago"] [Date "2018.05.05"] [Round "2"] [White "Menon, Gopal"] [Black "Wilson, Matthew"] [Result "1-0"] [ECO "B43"] [WhiteElo "2329"] [BlackElo "2083"] [Annotator "Wilson,Matthew"] [SetUp "1"] [FEN "2r1kb1r/1bq2ppp/pnnp1P2/1p2p1P1/4P3/PNN3QB/1PP4P/1KBR3R b k - 0 20"] [PlyCount "12"] 20... Rd8 {I knew that I was in trouble here} 21. Be3 { At the time, I thought that White should have traded on g7 first in order to open up the kingside. I quickly "punished" his "inaccuracy"} g6 $2 22. Bxb6 Qxb6 23. Nd5 { I was about to retreat to a7, but then I realized that 24.Nc7 was checkmate!} Nd4 24. Nxb6 Nxb3 25. Qxb3 Bxe4 26. Rhe1 1-0

Gopal went on to tie for 1st with 3.0/4. I finished the tournament with a win over a 2000 player, so my rating climbed to 2093.

E4stat visits the US Chess Championship

Congratulations to Sam Shankland, 2018 US Chess Champion. He scored an extraordinary +6 against a very tough field and pushed his rating over 2700. He also made my forecast look bad. I visited rounds 10 and 11.

The star-studded lineup:


*********************************************************************************************************************************************



Sam is about to clinch the championship here; he has a clearly winning position in Round 11 against Awonder Liang.

*********************************************************************************************************************************************

Awonder in Round 10, pressing in his game against Izoria. Awonder scored drew all his games against the Big Three. Back in January, he won the Jane Addams Memorial with a perfect 4.0/4 (e4stat tied for 8th with 2.5/4). 




*********************************************************************************************************************************************

This guy scored 2.5 points against the Big Three! 2600s are not to be underestimated. Here in Round 10, Izoria succumbed to Awonder Liang.



*********************************************************************************************************************************************

The only 2700 player to survive against Izoria. After the first 2 games, he was in contention for the Fischer Prize (11-0), but he finished with a "Giri" (all draws).


*********************************************************************************************************************************************

Wesley So in a very drawish rook ending against Robson in Round 10.


*********************************************************************************************************************************************

Ray Robson in Round 10



*********************************************************************************************************************************************

The next World Champion?



*********************************************************************************************************************************************

In Round 10, Zherebukh went into a deep think after Caruana unleashed ...Bg4! A few moves later, Caruana avenged his loss from the 2017 US Championship.



*********************************************************************************************************************************************

Onischuk had a tough tournament. In Round 10, Sam Shankland ground him down. Just one year ago, Onischuk tied for first with Wesley So but lost the playoff.



*********************************************************************************************************************************************

I would not say that Nakamura slammed the clock. But when I was watching another game, I heard someone hit the clock with emphasis. I glanced over. Nakamura had just unleashed e5-e6! against Akobian.





*********************************************************************************************************************************************

He was briefly in the lead, but Akobian fell apart later in the tournament. Here is his game against me in the Saturday Night Special
