A field of 542 players from 19 countries

Having to win every game is a major challenge. This also applies when GMs, round after round in an open tournament, are all but obliged to score points against untitled players.

Aware of this, Niclas Huschenbeth travelled to a multitudinous tournament in Florianópolis. With 542 participants, the rating favourites inevitably face a number of significantly lower-rated opponents in the early rounds. After two opening wins, the only German participant in the field had to come to terms with an initial disappointment as early as round three: he drew against Argentine untitled player Franco Acosta. The South American has exactly 399 rating points fewer than Huschenbeth, and arguably played the game of his life.

In round four, Huschenbeth lived up to his role as favourite once again. However, in the fifth round he was surprised by Diogo Duarte Guimaraes, who produced remarkably error-free play. Up to move 54 the game was absolutely level - the engine reported no notable swings at all. Then came the mistake. And it was not made by the FM - it was the GM who erred, and the game was already over six moves later.

A powerful 1.e4 Repertoire

Instead of forcing you to memorise endless lines, Raja focuses on clear plans, typical ideas, and attacking motifs that you can apply in your own games without delay. A short, focused, and practical repertoire.
Grandmaster Harshit Raja, India’s 69th GM, has created a practical and powerful 1.e4 repertoire - perfect for players who want to play aggressively without drowning in opening theory. Whether you’re playing online or over-the-board, this course gives you solid attacking weapons that are easy to learn, fun to play, and difficult for opponents to face.

Huschenbeth bounced back with a win over Brazilian NM Acyr Rogerio Calcado, and now stands in 52nd place with 4½ points to his name.

Two players are tied for first place with perfect 6/6 scores: 27-year-old Cuban IM Jorge Roberto Elías and 35-year-old Brazilian GM André Diamant.

Six players stand a half point back, including top seed José Martínez, who recently impressed by reaching the quarterfinals at the FIDE World Cup (he was knocked out by eventual champion Javokhir Sindarov). Also in the chasing group are second seed Aryan Tari from Norway and José "Pepe" Cuenca from Spain, who recently won a strong open in Temuco, Chile.

Understanding Middlegame Strategy Vol 12: Reversed Colour Systems – King’s Indian/Pirc Defence

In this video course, Grandmaster Ivan Sokolov explores the fascinating world of King’s Indian and Pirc structures with colours reversed, often arising from the French or Sicilian.
The King’s Indian Defence is one of the most dynamic openings in chess - and Pirc structures share much of the same DNA. With colours reversed (the King’s Indian Attack), these setups can be just as powerful. What may look modest at first often transforms into highly complex middlegames, where timing, precision, and a deep feel for dynamics make all the difference.
