The Fritz 20 Duel: Svitlana Demchenko vs. Bobby Fischer!

by Arne Kaehler
6/26/2025 – In this entertaining and instructive video, WIM Svitlana Demchenko faced the "Bobby Fischer" engine from Fritz 20 in a dynamic training match. She played the Scotch Gambit and managed to gain a clear advantage through sharp tactical play, sacrificing material for initiative and space. Despite a midgame slip that dropped her evaluation and confidence, she regrouped and navigated a complex endgame with precision, ultimately securing the win. The game showcased both instructive mistakes and brilliant ideas, making it a realistic and valuable learning experience rather than a flawless engine battle.

60m English New ideas in the Najdorf_E

‘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.
