Four players, three Candidates spots
The semifinals of the FIDE World Cup began on Friday in Goa, in what is now arguably the most decisive stage of the event. With three qualification spots for the 2026 Candidates Tournament at stake, winning a semifinal match guarantees a place in the tournament that will determine the next challenger for the World Championship – the single most important goal for elite players in the modern chess calendar.
In today’s fast-paced chess world, especially online, where blitz and rapid games dominate, the traditional approach of grinding through lines of opening theory can feel overwhelming, and even unnecessary. The real challenge? Striking the right balance in your opening preparation. How deep should you go? Where do you stop? This course is built on the timeless wisdom of my legendary coach, Chebanenko, who designed opening repertoires for his “lazy” students – not lazy in attitude, but smart in approach. His philosophy? Don’t memorise. Understand.
Both first games of the semifinal matches ended drawn, in 30 and 33 moves respectively, but the day nonetheless featured deep calculation, creative decision-making and high psychological tension.

In the encounter between Wei Yi and Andrey Esipenko, the contenders navigated a position that looked outwardly balanced but demanded extreme precision. The final sequence of the game illustrated just how difficult even apparently quiet positions can be at the top level, as both players calculated long tactical lines to force a draw.
Although no mating attacks appeared on the board, several tactical motifs – including subtle intermediate moves and hidden resources – made the conclusion of the game particularly noteworthy, as shown below in the annotations by GM Karsten Müller.
In this insightful video course, Grandmaster David Navara shares practical advice on when to calculate deeply in a position — and just as importantly, when not to.

The all-Uzbek semifinal, featuring Nodirbek Yakubboev and Javokhir Sindarov, produced a critical (and instructive) moment. The game entered a queenless middlegame in which Yakubboev, playing white, faced a crucial decision on move 20.
Club players would, perhaps, almost automatically choose 20.Rxc6, followed by 20…Kd7 21.Rc4, aiming for slightly more active rooks while keeping an eye on the potentially vulnerable e5-pawn. Commentators on the chess.com broadcast, including Judit Polgar, highlighted this as surely the intuitive continuation.
Instead, after spending 12 minutes in reflection, Yakubboev opted for 20.fxe3. Engine analysis confirmed this as the strongest move, despite the doubled pawn it creates, since it opens the f-file and gives White’s rooks additional squares and dynamic potential.
Yakubboev’s choice demonstrated elite-GM’s trust in concrete calculation, even though by that point he had already invested significantly more time than his younger compatriot – the clock showed almost a 40-minute deficit.
From there, White generated enough tactical ideas to defend the e5-pawn and seize a small initiative. Yet Sindarov had also foreseen the ensuing complications and responded accurately, neutralising White’s pressure at every critical juncture. With both rooks active and the position balanced, Sindarov played 30…Rg7 and offered a draw.
Under the regulations, offers are allowed only after move 30, and given the circumstances – Yakubboev had just 1 minute remaining to Sindarov’s 26 – the player with the white pieces accepted. In a different time situation, White might reasonably have played on, but practical considerations weighed heavily.
If one skill decides more games, it’s calculation. Openings fade, plans change – but seeing clearly, comparing lines, and choosing with confidence wins points. In this course GM Ganguly turns calculation into a trainable skill with a structured path for any level. You won’t just solve tactics; you’ll learn how to think: where to start, which branches to explore, when to stop, and how to keep a crystal-clear mental board under pressure.

The draw concluded a game that, while short on the scoresheet, reflected the depth and psychological nuance of elite-level play. Even in encounters that appear routine to spectators, a great deal of calculation, risk assessment and long-term planning unfolds beneath the surface – much of it never seen on the board itself.

Data, plans, practice – the new Opening Report In ChessBase there are always attempts to show the typical plans of an opening variation. In the age of engines, chess is much more concrete than previously thought. But amateurs in particular love openings with clear plans, see the London System. In ChessBase ’26, three functions deal with the display of plans. The new opening report examines which piece moves or pawn advances are significant for each important variation. In the reference search you can now see on the board where the pieces usually go. If you start the new Monte Carlo analysis, the board also shows the most common figure paths.
