Masters: Aronian on fire
Levon Aronian made a strong start to the Masters Triathlon at the Biel Chess Festival, scoring 9/10 to win the rapid section by a 3-point margin. The six-player single round-robin took place on Sunday, with 2 points awarded for a win and 1 for a draw.
The 43-year-old US representative opened with a draw against Aydin Suleymanli before winning his remaining four games. In three of those victories, Aronian reached favourable endgames and converted his advantages. The most entertaining of these three wins was seen in round three, when Aronian sacrificed a whole rook for an attack against Mexican grandmaster Jose Martinez.
In his final game, Aronian produced a 31-move win against Matthias Bluebaum’s French Defence. Bluebaum had won the Chess960 tournament on Saturday.
This compact course is designed specifically for practical play. Instead of overwhelming you with endless theory, it focuses on the critical lines, typical plans, and recurring tactical ideas. Looking for an opening that gets your opponents thinking on move one? Grandmaster Andy Woodward has relied on 1.b3 for years in blitz and bullet, using it to defeat strong masters and grandmasters who underestimated its hidden venom. While many players dismiss the opening as harmless, they often find themselves caught in unfamiliar positions, tactical traps, and uncomfortable middlegames. This compact course is designed specifically for practical play. Instead of overwhelming you with endless theory, it focuses on the critical lines, typical plans, and recurring tactical ideas that matter most when the clock is ticking.

Aronian played three of his five rapid games with the white pieces, meaning that he will have black three times during the first stage of the classical section.
Suleymanli, the only player to hold Aronian to a draw, finished alone in second place with 6/10. The Azerbaijani was also the only competitor besides Aronian to complete the single round-robin without a defeat. The other four players all scored four points or fewer.

Generations Challenge: Finek outscores Xiao and Materia
The rapid section of the Generations Challenge also produced an outright winner. The category brings together three players aged 16 or 17 and three leading female players, including former women's world champion Alexandra Kosteniuk.
Czech youngster Vaclav Finek finished first with 8/10 after recording three wins and two draws. Earlier this year, thanks to a sensational performance, Finek won the Challengers section of the Prague Masters. His advantage entering the classical stage is narrower than Aronian's, however, as China's Xiao Tong and France's Marco Materia (who won the chess960 event) both finished one point behind on 7/10.
Finek beat Materia in round one. The French youngster's position quickly collapsed after he played 21...Qg4?!
White is clearly better after the forcing 22.Ne3 Qh5 23.Bxb7 Rxb7 24.Qe4 Ra7 25.Nf5. Simple, positionally sound chess.
Black cannot defend both e7 and g7. White soon created a deadly attack on the kingside.
Doesn’t every chess game get decided by mistakes? Absolutely. But most players never truly comprehend that they are making the same kind of mistakes over and over again.
Vaishali Rameshbabu, the winner of this year's Women's Candidates Tournament, endured a difficult rapid event. She obtained one win and lost her remaining four games, leaving her with 2/10 points going forward.
The classical section of both triathlons begins on Tuesday.

‘New ideas in the Najdorf – a Power Play 18 Update’ aims to complement Daniel King’s popular DVD from last year ‘The Sicilian Najdorf - a repertoire for Black’. Such a dynamic and popular opening as the Najdorf is developing the whole time. On this download, Daniel King updates lines that were included on his DVD but also responds to viewers’ requests, considering lines that he omitted from his original repertoire. The lines examined on this update are:
• 1 e4 c5 2 Nf3 d6 3 d4 cxd4 4 Nxd4 Nf6 5 Nc3 a6 6 h3 e5 7 Nde2
• 5….a6 6 Bc4 in combination with the English Attack (Be3, f3 etc)
• 5…a6 6 Be3 and the …a5 variation
• 5…a6 6 Be2 and 9 Re1
• 5 f3 (instead of 5 Nc3)
It isn’t necessary to have seen the original Najdorf DVD to understand the lines examined here – but it would help as they form part of a complete repertoire.
