As the sun set on North Goa’s Arpora, Arjun Erigaisi would have rued a missed opportunity. Having let China’s Wei Yi salvage a draw from a precarious position, the Indian grandmaster had left with little cause for satisfaction as the FIDE World Cup quarterfinal went into a tie-breaker on Tuesday.The match assumes added significance as the winner stays in the hunt for a spot in the Candidates Tournament to be held later in the year. After the two Classical contests failed to produce a winner, the match will be decided in shorter time formats on Wednesday.Tuesday’s match began on expected lines, with Arjun looking to press for an advantage with white pieces after a quick 31-move draw in the first classical game. He started the second game solidly with a Queen’s Gambit Declined, but the middle game took a dramatic turn.Wei Yi spent 36 of his 53 remaining minutes on a questionable Queen to c6 (20…Qc6?!) move, a positional misstep. This mistake was compounded just a move later when the Chinese misplaced his knight to d7 square (21…Nd7?!), which allowed Arjun to launch an attack on Black’s rook on c5 and grab the initiative.At this moment, Arjun had the chance to land a decisive blow. The engine-recommended line suggested a bishop sacrifice to force a superior endgame. With equal pawns but a bishop and knight against Wei Yi’s knight pair, the resulting position would have been extremely difficult for the Chinese grandmaster to defend. As it turned out, a solid, equal material endgame resulted in a draw after just 32 moves.Now the two players will go into a high-pressure battle for survival in the tie-breaker. The format comprises increasingly faster games, beginning with two 15+10 rapid games, followed by 10+10 rapid if needed. Then there will be blitz contests until a winner is found.INTERACTIVE: Arjun Erigaisi vs Wei Yi 2nd Quarterfinal GameArjun can draw confidence from his recent history against Wei Yi. At Norway Chess 2025, he dominated their tie-break encounters. After an initial draw with black pieces, Arjun defeated the Chinese in the Armageddon tiebreak. When they met again later in the tournament, the result was the same – a hold in the classical game followed by a decisive victory for the Indian in the tie-breaks.Story continues below this adTough taskHowever, Wei Yi is no ordinary player. A prodigy who became a Grandmaster at 13 and the youngest player ever to cross the elusive 2700 Elo mark at 15, his career trajectory once suggested he could be the next world champion. While his career then entered a prolonged slump, with stagnating performances and stalled growth, he remained one of the game’s most skilled tacticians.Now, Wei Yi seems to have rediscovered his form. An individual gold at the 2022 Asian Games, the prestigious Tata Steel Masters title in 2024, a career-high Elo of 2755, and a world No. 9 ranking, all signal a resurgence.The trend that saw Arjun and Wei Yi draw their Game 1 in just 59 minutes continued on Tuesday, but on a different board as Uzbek sensation Javokhir Sindarov and Peruvian-Mexican Jose Eduardo Martinez Alcanatara ended their Game 2 after a record 18 minutes and 29 seconds. Understanding the skewed risk-to-reward ratio, they agreed to a 25-move draw, extending Martinez Alcantara’s fairytale run and moving the match into tie-breaks, a format where the odds now favour him. But ruling the formidable Sindarov out would be premature.A victory for Sindarov in the tie-breaker would guarantee Uzbek representation at the 2026 Candidates Tournament in Cyprus. With Nodirbek Yakubboev becoming the first player to advance to the semifinals after beating Germany’s Alexander Donchenko and sharing the same bracket as his compatriot, the tournament could well see an all-Uzbek semifinal.Story continues below this adThis will guarantee that at least one Uzbek player will reach the final and secure a Candidates spot. There is even a possibility that both could qualify, should the loser of their semifinal win the third-place playoff.Donchenko, who had lost to Yakubboev with black pieces in their first game, failed to turn the tables on Tuesday. Donchenko’s loss also ended German participation in the World Cup, after four of their players made the round of 16.The battle between Russia’s Andrey Esipenko and Sam Shankland of the United States also ended without a decisive result after two days, meaning three quarterfinals will need tie-breaks to decide the outcome.Results:Andrey Esipenko (RUS) drew with Sam Shankland (USA); Jose Eduardo Martinez Alcantara (MEX) drew with Javokhir Sindarov (UZB); Arjun Erigaisi (IND) drew with Wei Yi (CHN); Alexander Donchenko (GER) lost to Nodirbek Yakubboev (UZB).
