The Unbreakable Will || Praggnanandhaa vs Wei Yi || FIDE Candidates Tournament 2026 R9

This video summarizes a game from round nine of the 2026 Candidates Tournament between Praggnanandhaa (playing white) and Wei Yi (playing black). The commentator expresses excitement for the game, noting its importance in the tournament, and promises to cover a specific game from the Menorca Open immediately after this one. The game begins with Praggnanandhaa opening with d4, and after a series of standard moves, the Queen's Gambit Declined, specifically the Semi-Tarrasch variation, is on the board. Praggnanandhaa plays bishop to g5, a less common but still popular move. Wei Yi responds by capturing on c4, deviating from the main lines. Praggnanandhaa recaptures with the d-pawn, and after Wei Yi plays bishop to e7, Praggnanandhaa captures the bishop on c4. Both players castle kingside, and Wei Yi develops his bishop to d7. The game enters a new territory on move 10 with Praggnanandhaa's knight to f3, a move not previously seen in this position. Wei Yi responds with knight to c6, and Praggnanandhaa immediately plays pawn to e4. After rook to c8 and queen to e2, Wei Yi plays knight to g4. Praggnanandhaa avoids the trade with bishop to f4, and Wei Yi then plays bishop to f6, attacking the rook. After rook to e8, Praggnanandhaa aligns his rook with the black queen by playing rook a to d1. Wei Yi attempts to simplify by playing knight g to e5 to trade pieces. Praggnanandhaa obliges, and after the bishop recaptures, it retreats to b3. Wei Yi then moves his queen to b6, adding pressure to the diagonal and the b2 pawn. Praggnanandhaa captures on e5, knight recaptures, and Praggnanandhaa plays king to h1, preparing for pawn to f4. Wei Yi plays rook c to d8, and Praggnanandhaa advances his queen to h5. Knight to c6 is played by Wei Yi. At this juncture, the commentator notes that most players would opt for a rook lift (rook d3 or rook h3). However, Praggnanandhaa plays pawn to e5, a move in the spirit of the Harry Nelson Pillsbury variation of the Semi-Tarrasch, aiming to free up the e4 square for his knight. The commentator illustrates how this move can lead to decisive attacks, showing a line where knight to e4 leads to a winning advantage for white. Wei Yi responds to e5 with queen to b4, preventing the knight from going to e4. Praggnanandhaa then executes the rook lift with rook d3. Wei Yi defends, but the commentator points out that he played queen to f4 too early, suggesting that moves like h6 or rook f8 should have been played first. Praggnanandhaa seizes the opportunity by playing rook f3. After queen captures on e5 and queen captures on f7, Praggnanandhaa's position looks strong. King to h8 and rook a to d1 follow. Wei Yi offers a rook trade with bishop to c8, which Praggnanandhaa declines, instead playing h3 to create luft for his king. Rook captures on d1, knight captures on d1, and rook g8 are played as the rook was hanging. The game continues with rook e3, queen to d6, and knight to c3. Wei Yi's best hope is queen f8 to survive the endgame, which would likely involve losing a pawn and trading pieces. However, Wei Yi plays knight to d4, and Praggnanandhaa plays knight e4, attacking the queen. Queen to e5 is played to stop knight g5. Praggnanandhaa then plays pawn to f4, which the commentator identifies as the only winning move. The position becomes critical. The commentator highlights knight d6 as the winning move, threatening a smothered mate. He demonstrates how various responses from black, like trading queens or playing queen f6, lead to a decisive advantage for white. Wei Yi plays queen to c5, defending the bishop and inviting rook to c3, which would lose the knight. Praggnanandhaa plays queen to e7, threatening knight f7 mate. Wei Yi checks with queen c1, and Praggnanandhaa moves his king to h2. Black cannot capture the rook due to the mate threat, so h6 is played, creating space for the king. The rook on e4 is hanging, and Wei Yi plays rook e4. Praggnanandhaa plays knight captures on b3, and after a captures, king to h7 is played. Wei Yi is surviving, but the position is difficult. Rook c4 is played, and the commentator notes that Praggnanandhaa seems to be winning a piece, but Wei Yi finds a strong defensive move, rook d2, with only 38 seconds on the clock. Praggnanandhaa, with limited time himself, plays queen to c7, aiming to add a third attacker. Wei Yi plays b5, trying to survive until time control. Praggnanandhaa plays rook to c2, which would have been decisive. However, he plays rook to e4 instead, to defend the f4 pawn. The commentator notes this was a missed opportunity. The game reaches move 40, and additional time is granted. Rook f1 is played, and Wei Yi plays bishop to a6. The commentator states that the only winning move for Praggnanandhaa is pawn to b4, which would have trapped the bishop and secured a win. However, Praggnanandhaa plays queen to c6, which only draws. The game continues with rook d8, knight f7, rook d7, queen e4 check, pawn g6, and pawn f5. The commentator analyzes potential mating sequences if rook captures on f7, showing how white could force mate. However, Wei Yi defends precisely by playing pawn captures on f5. Queen to e8 threatens mate, and queen d4 stops it. Rook f3 followed by rook c7 is played by white, and the commentator suggests that Wei Yi might even be pushing now. The game reaches a complex endgame. Rook to g7 is played, and knight to f7 threatens mate. Rook g8 attacks the queen, and queen e7 threatens discovered attacks. Wei Yi finds queen to g7 to defend. Rook d3 is played by Praggnanandhaa, and the commentator believes he realizes he is no longer better and is even down a pawn. Bishop to c8, rook c3, rook f8, rook c7, and king g8 are played. Wei Yi finds king to g8, which holds the draw. The commentator concludes that Praggnanandhaa missed the pawn to b4, the only winning move, but Wei Yi played exceptionally well to defend. The game ends with a queen trade and a draw agreed on move 56 after knight captures on c8. The final position is analyzed, showing that white would have won a pawn and the game. The commentator expresses admiration for Wei Yi's resilience and highlights how engine evaluations don't always reflect the practical difficulty of converting an advantage against a strong defender. He reiterates that pawn to b4 was the key. Finally, the commentator shows the updated standings of the Candidates Tournament, with Ivanchuk leading. He then thanks his patrons and signs off, promising to cover the Menorca Open game next.
