Matthias Wüllenweber on Fritz 20: More Fun, More Style, More AI

6/4/2025 – The conversation with Matthias Wüllenweber about Fritz 20 highlights the numerous innovations in the new version: A key focus is on the new opponent characters, including legends like Fischer, Lasker, Capablanca, and Karpov. Another highlight is the AI-powered voice commentary, featuring over 170 chess-related themes that provide both entertainment and educational value—available in multiple languages if desired. In addition, the opening repertoires of real chess legends like Fischer have been integrated, and the new "Bullet Training" mode offers practical time-management training against realistically acting opponents. The newly improved engine is also a major upgrade and presents an independent analysis alternative to Stockfish.

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.
