Grebnev reclaims solo leadership with two rounds to go in Dubai chess tourney
Grandmaster (GM) Aleksey Grebnev of Russia once again distanced himself from the field with a hard-fought win against International Master (IM) S. Rohith Krishna of India in Monday night's seventh round of the 25th Dubai Open Chess Tournament at the Dubai Chess and Culture Club.
Grebnev captalised on a series of blunders by Krishna in what was otherwise an equal position to dispose of his erstwhile co-leader and take the tournament lead with six points. The 18-year-old Russian is trailed closely by two other teenage grandmasters three years his junior - his compatriot Ivan Zemlyanskii and Sina Movahed of Iran, who both have 5.5 points.
Movahed, who turned 15 last week during the tournament's opening day, and Zemlyanskii, two months shy of his 15th birthday in August, scored the biggest scalps of the round after defeating defending champion GM Mahammad Muradli and top-seed GM Nihal Sarin, respectively.
Movahed inflicted Muradli's second consecutive loss in the tournament. Muradli was on the backpedal right out of the opening as Movahed sacrificed a pawn to weaken the Azerbaijani's kingside defence. Movahed, however, could not find the precise continuation to convert his advantage until a greedy pawn grab by Muradli on the 39th move allowed the Iranian to launch an overwhelming attack with all his pieces contributing to the onslaught. Muradli resigned three moves later.
After being held by two consecutive draws, Nihal, playing the black pieces, once again took big risks to play for a win. The ploy initially worked as he started to create weaknesses around white's kingside, but the Indian failed to find the most accurate way to sustain the offensive, allowing Zemlyanskii to force an exchange of queens that neutralised the attack and left him a pawn up in the endgame.
Grebnev will have the black pieces as he tries to protect his lead when he faces Movahed in the next round.
In Category B, Fide Master (FM) Mahdi Nikookar of Iran ended his perfect run after a draw with Sri Lanka's Pesandu Rashmitha Liyanage in the seventh round. Nikookar, however, remains the solo leader with 6.5 points, followed by Liyanage and Indian Candidate Master (CM) Alankar Sawai Vandan with six points each. Vandan defeated Armenia's Davit Baghdasaryan.
The tournament follows a 9-round Swiss system with a 90-minute time control plus a 30-second increment per move. Games are played every day from 5pm, except the final round on June 4, which starts at 10am. The awarding ceremony is on June 5.
The tournament offers a prize pool of $52,000 to be handed out to the winners of both categories. Category A, contested by players with a rating over 2300, has a total prize fund of $39,500 with $12,000 going to the champion, while Category B, open to players rated below 2300, offers $12,500 in total prizes and $2,000 awarded to the champion.
Special prizes will also be distributed to top performers among rating categories, unrated, youth, women, and UAE players.
Chess fans from around the world can watch the Category A games live on the club's website as well as chess platforms such as lichess.org and chess.com.
Earlier, International Master (IM) S Rohith Krishna of India defeated defending champion GM Mahammad Muradli to rise to the top of the standings in a tie with Grandmaster (GM) Aleksey Grebnev after Sunday night's sixth round.
Grebnev drew with top-seed GM Nihal Sarin on the first board, allowing Krishna to join him for the lead with five points each. Nihal remains in joint second place with 4.5 points, alongside his compatriot GM Bharath Subramaniyam, GM Zemlyanskii, GM Shant Sargsyan, and GM Movahed.
Muradli sacrificed a pawn on move six in a delayed Benko Gambit and a few moves later the game reached a position that was previously seen in a game between world number two Hikaru Nakamura and former FIDE world champion Ruslan Ponomariov. Muradli, however, deviated on move 13, a questionable decision that allowed Krishna to gain time to reinforce his central pawns and plant an uncontested knight on the c4-square, the white knight's ideal outpost in the Benko Gambit.

Israeli strikes hit centrifuge facility in Iran's Isfahan: IAEA
Israeli air raids have damaged a centrifuge manufacturing workshop in the central Iranian city of Isfahan, the International Atomic Energy Agency (IAEA) confirmed on Saturday. According to the agency, the site did not hold any nuclear material, and the strike is expected to have no radiological impact. The Israeli military stated earlier that its air force had targeted a nuclear facility in Isfahan overnight. The site, also struck at the start of Israel's current operation, plays a role in uranium conversion — a key stage in the enrichment process. Later, the Israeli army, according to the Israeli daily Haaretz, confirmed that the target was a facility inside the complex used to produce centrifuges, essential for uranium enrichment.

Hydraulic Fault Grounds UK F‑35B in Kerala for Days
A British Royal Navy F‑35B Lightning II remains immobilised at Thiruvananthapuram International Airport after declaring an emergency on 14 June. The pilot reported low fuel amid rough sea conditions over the Arabian Sea before the jet, deployed from HMS Prince of Wales during the Indo‑Pacific Operation Highmast, touched down at 21:28 IST. The Indian Air Force's Integrated Air Command and Control System coordinated the diversion alongside civilian air traffic control, declaring a full-scale emergency to ensure safe handling. Initial refuelling took place on Sunday under IAF supervision, but the aircraft could not return to the carrier due to a hydraulic system failure. Royal Navy technicians arrived via helicopter from the carrier that night and began repair operations, but their efforts remain unsuccessful six days on. Additional British and American technical personnel—possibly including Lockheed Martin experts—have since taken charge, while a larger maintenance team is expected. If repairs remain inconclusive, the jet may be airlifted back aboard a military transport aircraft. Valued at over $100 million, the F‑35B represents one of the world's most advanced and expensive combat aircraft, equipped with short take‑off and vertical landing capability, stealth design, networked sensors, and naval adaptability. Its unscheduled landing in India highlights both the logistical complexities of advanced military aviation and the robust coordination between allied forces. ADVERTISEMENT Security protocols have been stringent. The aircraft is stationed in Bay 4 under armed Central Industrial Security Force guard. The British team rejected offer to relocate it to a civilian hangar or protective shed, citing confidentiality concerns over sensitive systems, and insisted on repairs in open view under controlled conditions. Meanwhile, Royal Navy personnel, including the pilot and technicians, remain onsite with food and lodging provided by airport authorities, with Indian teams facilitating logistics throughout. The incident marks the first unscheduled landing of a foreign-manufactured F‑35 on Indian territory and comes amid growing UK‑India defence cooperation. The jet had been flying as part of joint maritime exercises, including PASSEX drills with INS Tabar and other British ships in the northern Arabian Sea on 9–10 June. Analysts have noted the deployment underscores interoperability and strategic alignment between both nations, rather than any response to Middle East tensions. Within 48 hours of landing, the aircraft had been refuelled and initially positioned for departure. However, the discovery of hydraulic malfunction extended its stay, prompting the dispatch of specialists from the UK and the US. Defence officials confirmed that the jet could be repatriated on a cargo plane if ground repairs remain unfeasible. The episode has drawn public attention not only for its rarity but also for the international coordination displayed. Local observers are closely watching developments, while military commentators underscore the necessity of emergency recovery airfields like Thiruvananthapuram for carrier-based operations during unpredictable monsoon-season weather. As of 20 June, the jet remains on the tarmac, awaiting either restoration or return via air transport. With a multinational technical team now assembled, a departure window is expected later this week—subject, of course, to successful hydraulic repair and formal clearances under Indian aviation protocols.
