Petroff Defence Powerbase 2026

 A double click on the database loads the games list. A further double click loads the relevant game. Via the tab Players it is possible to sort the games according to frequency (with the tab Total). There David Paravyan is at the top of the list with 541 games. It is also worth studying the games of Yu Yangyi (151 games), Ian Nepomniachtchi (148) and Daniel Fridman (152). Of further interest is a click on Title; (for that an up-to-date player encyclopaedia needs to be installed) when one sees that many of the world champions had the Petroff in their repertoire or indeed still have it (especially Kramnik and Karpov).

The games can be played through or further investigated with an engine or a Powerbook.
