Nyzhnyk shared first

Peruvian Grandmaster Jorge Cori, a member of the super-strong Webster University chess team, won his last two games to catch Illia Nyzhnyk atop the annual SPICE Cup standings and force an Armageddon playoff.

Cori is having a great year — the 23-year-old  won a gold medal on board three at the Batumi Olympiad after posting a 2925 performance rating, and is now approaching 2700 Elo.

In St. Louis he and drew three won five games — the most of any player — which made up for his second-round loss to Awonder Liang in a wild game.

 

Cori's 15...Ne8 was asking for trouble (Ne4 would keep the game equal) and Liang pounced with 16.Qh3 f5 17.g4! prying open the g-file and the b1-h7 diagonal.

Liang missed several chances to put the game out of reach early, notable on move 28:

 

Liang's 29.a3 is based on the fact that if the b4-bishop leaves the a3-f8 diagonal White mates with Bc5+ and Qg7#. But Cori found the only saving move 29...h5! when Liang is still better after 30.Qg5 but Cori could hope to untangle and survive the endgame after 30...Qe7 (not played) 31.axb4 Qxg5.

Instead, from the diagram position, the crushing blow was 29.f5, hitting the bishop laterally. Black has the same problem as above, but this time there's no defence.

Nyzhnyk was leading the tournament by half a point going into the last round after beating Benjamin Gledura with the black pieces. Gledura had the best start winning his first four games but 2 points from his last five games (including his loss in the penultimate round) left him tied for 3rd.

 

White looks to be holding after 39.Ra7+, as he will be able to pick off the e-pawn, for instance, 39...Kd6 40.Kf2 Nxh2 41.Ke3. But in the game after 39.Kf2 Kb6 40.Ke3 Rxe7 41.h3? Nyzhnyk held onto the pawn with 42...Nh4 42.Rf1 (one move earlier this may still be drawing) 42...Ng2+43.Ke2 e3 and soon advanced it to e2 winning.

Cori's crucial last round win came at the expense of Alex Lenderman who fell into a trap:

 

Lenderman played 24...Bb8. Can you spot the problem?

25.Qxd5! exploiting the pin and winning a clear pawn after cxd5 26.Rxc8 Re8 27.Rxd8

Cori went on to win easily a few moves later and reached 6½ points to force the Armageddon playoff:

@chessdrummer - Thanks. Fixed. Annoyingly, the USCF doesn't produce usable tables (the old MSA really is showing its age), the tournament stopped using Chess-Results in 2016 and the JPG image file for the cross table was of terrible quality. So I improvised (badly).

Please changes the flags unless... Cori, Nyzhnyk, Glendura, Shimanov and Bruzon are now representing Egypt; Bok, Quesada and Chandra representing Zambia; Liang is Algerian and Lenderman is Mozambican. :-)
