7/9/2025 – Svitlana presents an unconventional yet effective way to combat the English Opening by responding with 1...e5 and then an early ...h5, aiming to unsettle White's typical kingside fianchetto plans. The line offers dynamic attacking potential with ideas like ...h4, or even ...g5, depending on how White responds, and even top blitz players have experimented with it. While engines consider some White responses (like Nf3 followed by h4) slightly better, the surprise value and aggressive intent behind this line make it a strong practical weapon, especially in blitz and rapid games.
7/7/2025 – Robert Ris faces off against the legendary Mikhail Tal in Fritz 20's grandmaster-level mode. With playful banter and strategic reflections, he navigates a tense middlegame filled with attacking chances, tactical bluffs and surprising defences. Despite some miscalculations and a critical blunder that nearly costs him the game, Robert defends resiliently, showcasing both fighting spirit and self-deprecating humour. Finally, after a flurry of complications and a tense queen endgame, the game concludes in a threefold repetition - a well-earned draw against one of history's most fearsome attackers.

6/28/2025 – In this episode, Svitlana offers a comprehensive guide on how to play against the King's Gambit, an aggressive and historic opening that begins with 1.e4 e5 2.f4. While it's less common in high-level chess today, it still appears in club-level play and can lead to sharp tactical battles. Svitlana walks through multiple lines, including sideline traps and the main variations with 3.Nf3 and 3.Bc4, emphasising key defensive setups for Black, such as the flexible ...Nf6 line and the importance of early counterplay. She highlights thematic tactics, development priorities, and typical traps, ultimately showing how to neutralize White's initiative and even seize the advantage with correct preparation.
6/27/2025 – In this episode of The Underdog with Robert Ris, we witness 13-year-old IM Kagan Ahmad from Azerbaijan defeating world blitz legend Hikaru Nakamura in a dramatic 112-move battle during the World Blitz Team Championship. Despite Hikaru’s deep experience and early initiative in a quiet Anti-Sicilian, he blunders with 21.h4, falling into a tactical shot Nxe5, allowing Ahmad to seize material and survive. Ahmad defends tenaciously, even under extreme time pressure, finding key tactical resources like Qa2 and Qf6 with only seconds on the clock. The endgame sees Hikaru applying relentless pressure, but Ahmad methodically converts his advantage and finishes with a brilliant checkmate sequence—proving that even the greatest can be toppled, and that this young prodigy might soon be making waves in the global chess scene.

The episode highlights how classical games still offer valuable lessons, especially in regard to positional dominance and long-term planning.

A major highlight is the analysis of a game by a 14-year-old Vietnamese IM, who has become the most prominent adopter of a unique variation still lacking a formal name. The episode is filled with tactical lessons, strategic insights, and humorous commentary, all while inviting viewers to help name the emerging system. | Photo: John Upham

5/14/2025 – In this episode of Svitlana’s Smart Moves, Svitlana Demchenko introduces the Hedgehog pawn structure, a strategic setup common in the Sicilian Defense, featuring black pawns on a6, b6, d6, and e6. She emphasizes the educational value of understanding pawn structures for overall middle-game improvement, using a Kasparov–Kramnik game as a case study. Svitlana explains typical plans for both sides: white often uses space advantage and looks for a queenside breakthrough with moves like b4 and c5, while black prepares central or queenside pawn breaks like d5 or b5, and, much to Arne's delight, may even launch a kingside attack with …g5. But it might be better to stick to the queenside pawn advancing!
4/29/2025 – GM Chris Ward introduces a fresh and evolving variation in the Sicilian Dragon, humorously dubbed the "Accelerated Dragadorf", which merges dragon setups with thematic ideas from the Najdorf.

The second part covers a clean positional win in a more traditional Dragon, culminating in a delightful rook endgame puzzle, followed by Chris sharing personal insights on his early use of chess engines like Fritz. | Photo: John Upham

Both games, though seemingly equal in rook endgames, were decided by subtle inaccuracies and the strategic importance of king activity and piece placement. Svitlana emphasizes how small endgame advantages—such as a more active king or minor positional tweaks—can determine the outcome even in positions that look like simple draws.
