IM Richard Palliser outlines a combative Trompowsky (1. d4 Nf6 2. Bg5) repertoire for White. The lines analysed deal with all of Black’s common responses. A perennial favourite of creative players, the ‘Tromp’ sets Black complex problems from the very beginning. It has been played by Anand in a World Championship match and used as a surprise weapon by Carlsen, Nakamura, Erigaisi, Praggnanandhaa and many other top players. While offbeat, the Trompowsky is difficult to face. One colourful variation outlined within is the audacious 1. d4 Nf6 2. Bg5 Ne4 3. h4!? – a favourite of ‘Mr Trompowsky’, the four-time British Champion, Julian Hodgson. Leading to unusual and rich middlegame play, this variation maintains its venom in 2024.
