Round 5 Results
| White | Result | Black | Opening | Moves | |-------|--------|-------|---------|-------| | Erigaisi | 1-0 | van Foreest | Slav Defense (D11) | 30 | | Grandelius | ½-½ | Abdusattorov | QGD Exchange (D53) | 29 | | Carlsen | 1-0 | Zhu Jiner | King's Indian Attack (A05) | 41 | | Woodward | ½-½ | Erdogmus | Queen's Indian (E12) | 104 |
Erigaisi Punishes Van Foreest's Blunder
Erigaisi produced the cleanest win of the round. After queens were exchanged on move 19 in a Slav Defense, the Indian GM maintained a small positional edge. The game looked like it might fizzle into a draw until van Foreest played the fateful 25...e5??, a pawn break that looked active but was a decisive mistake.
The engine evaluation jumped from 0.4 to 2.5 in one move. Erigaisi's e-pawn marched forward with devastating force: e5-e6-e7, creating an unstoppable passed pawn. Van Foreest tried to complicate with 29...Rxa4, but 30.Rd8 was crushing. Resignation came immediately.
Erigaisi now has 3½/5 and is tied for first. After a quiet start with two draws, he has won three straight games.
Carlsen Recovers With Scrappy Win Over Zhu
This was far from vintage Carlsen. The world No. 1 chose the King's Indian Attack but drifted into trouble with 14.Nh4? and 20.f3?, handing Zhu a significant advantage with the engine showing -1.5.
Zhu couldn't hold the thread. Her 20...Bh8? and 21...Bxf6? gave the advantage back, and the game descended into a mutual time scramble with both players under 3 minutes. Carlsen found his way through the chaos better, and Zhu's 36...Ng3+?? was the final blunder that ended the game.
Not pretty, but effective. Carlsen is back to 3/5 and within half a point of the leaders heading into the final two rounds.
Erdogmus Escapes in a 104-Move Marathon
The longest game of the tournament so far saw Erdogmus survive a scare against Woodward. In a Queen's Indian, Woodward built steady pressure through the middlegame and into a queen endgame where he held a small but persistent edge.
The critical moment came when Erdogmus, down to his last seconds before the time control, played 35...b4?? - the engine jumped to +3.9 and Woodward was winning. But two moves later, Woodward returned the favor with 37.Qe5??, bringing the evaluation crashing back to 0.0.
What followed was 67 more moves of queen maneuvering in a dead drawn position before the players finally agreed to a draw by repetition on move 104. A lucky escape for Erdogmus, who keeps his share of the lead.
Grandelius Gets His First Half-Point
After four straight losses, Nils Grandelius finally found a result. In a QGD Exchange variation against Abdusattorov, the Swedish GM played solidly and the position simplified to a dead draw by move 20. The players agreed to a repetition on move 29.
It's a modest result - ½/5 on home soil is still a tournament to forget - but at least Grandelius is off the mark. Abdusattorov stays at 3/5, within touching distance of the leaders.

Looking Ahead
Two rounds remain, and the race is wide open. Erigaisi and Erdogmus lead, but Carlsen and Abdusattorov are just half a point back. A win in either of the final two rounds could swing the tournament.
Meanwhile, the Grand Chess Tour opened in Warsaw with a dramatic Day 1 of rapid play: five players share the lead after three rounds, and Niemann beat World Champion Gukesh.
