Mark Crowther (Sat Jul 11 12:20:23 2026)

Sergei Tiviakov beat Erwin L'Ami and Eric Van den Doel on the way to the final. There he met 24-year-old Liam Vrolijk who he beat 2-0 in a blitz tie-break after both their classical games were drawn. Machteld Van Foreest won the women's title beating Anna-Maja Kazarian 2-0 in the final.

Surprise victory for Mukhiddin Madaminov in the 3rd UzChess Cup

3rd UzChess Cup 2026 9

Mark Crowther (Tue Jun 16 08:32:29 2026)

19-year-old Mukhiddin Madaminov made a name for himself in winning the 3rd UzChess Cup Masters. He beat Shamsiddin Vokhidov in a blitz tie-break after they tied on 5.5/9. In the final round Madaminov had a long game against Hans Niemann where he was pressing for a win but Niemann also had a late chance to win himself.

Blohberger beats Navara 3.5-2.5 in a match

Navara vs Blohberger Match 2026 3-4

Mark Crowther (Sun Jun 14 07:23:52 2026)

A win in game three proved to be enough for Felix Blohberger to defeat David Navara in a six game classical match. Game four was probably the most exciting.

Faustino Oro earns his final GM norm in Sardinia

Sardinia World Chess Festival 2026 9

Mark Crowther (Mon May 11 04:55:29 2026)

Faustino Oro is now the second youngest player in history to become a GM after a 6/9 result in Sardinia. I suspect he will be more relieved than anything else after chasing this final norm for five months. He is already among only a select few who have earned the Grandmaster title at such a young age.

112th British Chess Championships 2026

112th British Chess Championships 2026 Games and Results

Mark Crowther (Sun Aug 9 19:46:00 2026)

The 112th British Chess Championships took place at the University of Warwick 1st to 9th August 2026. Luke McShane, Michael Adams, Shreyas Royal, Harry Grieve etc. Most interesting is the number of young players with Bodhana Sivanandan being one of those. The event delivered on its promise with 17-year-old Shreyas Royal earning his first title and Bodhana Sivanandan winning a tie-break match against Trisha Kanyamarala to win her first title at a record breaking 11-years-old, the women competed in the main championship and Bodhana's only loss was to the winner. It was only a few years ago that the British was a depressing run down affair making me wonder where all the juniors were, well they were just getting started at that point apparently.
