Stefan Liebig, born in 1974, is a journalist and co-owner of a marketing agency. He now lives in Barterode near Göttingen. At the age of five, strange pieces on his neighbour’s shelf aroused his curiosity. Since then, the game of chess has cast a spell over him. Flying high in the NRW youth league with his home club SV Bad Laasphe and several appearances in the second division team of Tempo Göttingen were highlights for the former youth South Westphalia champion.

4/11/2026 – At the Menorca Chess Festival, one player is naturally in the spotlight: reigning world champion Gukesh Dommaraju. While on another, more easterly Mediterranean island his World Championship match opponent is being determined, the 19-year-old is taking part in a small but highly competitive rapid chess tournament. Following a series of disappointing results and his decision to significantly reduce his tournament schedule, he announced that he would forgo his place in this year's Grand Chess Tour. | Photo: Saji Mathew

3/22/2026 – The Sicilian has long been one of the most popular openings. It therefore makes perfect sense for White to consider 1.c4. ChessBase author Nico Zwirs takes a look at similar, but reversed structures. His 60 Minutes course is aptly titled “Reversed Sicilian Power.” And since the Sicilian cannot be played without tactics, this new February release also fits the theme perfectly: Oliver Reeh’s new Master Class tactics volume offers exercises for players of all levels, regardless of their opening repertoire. | All photos: ChessBase

3/6/2026 – Drama at the Prague Masters. Many had already resigned themselves to two draws and an unchanged situation at the top of the table. But then Jorden van Foreest lost the long-balanced game against Aravindh Chithambaram, surrendering his lead in the standings to Nodirbek Abdusattorov. The Uzbek GM was able to capitalise on a blunder by the previously in-form David Navara to secure the win. The duel between world champion Gukesh Dommaraju and Vincent Keymer ended in a draw after a long battle, as did the game between Nodirbek Yakubboev and Parham Maghsoodloo. Hans Niemann managed to score his first victory in his game against David Anton. The final round begins four hours earlier than usual, at 11 a.m. | Photo: Nils Rohde / ChessBase
3/4/2026 – David Navara is playing an excellent tournament in his hometown. After round six of the Masters in Prague, he is only half a point behind the leader, Jorden van Foreest, together with Nodirbek Abdusattorov. The direct encounter between Van Foreest and Navara ended in a draw. At the other end of the table, a player stands alone: none other than Gukesh Dommaraju. The world champion, still without a win, has lost his third game of the tournament. Against his compatriot Aravindh Chithambaram, he squandered a good position while in time trouble. Hans Niemann and Vincent Keymer drew the longest game of the day. | Photo: Petr Vrabec / Prague Chess Festival
3/2/2026 – Mikhail Antipov won the Saint Louis Masters ahead of Fabiano Caruana. The Russian-born grandmaster, playing under the US flag, scored an impressive victory over Andy Woodward in the final round. He had gone into the last round level on points with the rating favourite. However, Caruana was only able to add half a point to his tally after drawing with Francesco Sonis, despite having reached a winning position. As a result, Caruana finished half a point short - the same half point he had voluntarily given up by requesting a bye in round five. | Photo: Lennart Ootes
