Reti Opening Powerbase 2025 is a database and contains 10989 high-class games from the Mega 2025 or the Correspondence Database 2024, 1069 of which are annotated.
The 1069 selected annotated games provide excellent study material. Top players such as Carlsen (1 annotated game), Anand (2), Anton Guijarro (1), Aronian (1), Duda (1), Eljanov (1), Firouzja (2), Giri (6), Kramnik (4), Navara (2), Nepomniachtchi (1), Praggnanandhaa (1), Radjabov (1), So (2), Vidit (3), Wojtaszek (1) have analysed their games, plus the comments of Reti experts such as Ribli (181), Horn (140) and Marin (101). In total there are 10989 games, whereby the rating average is at least 2615, except for games with commentaries or by the Reti experts Hikaru Nakamura (1034) and Rasmus Svane (832) as well as Vladimir Kramnik (310).
The Reti Opening Powerbook 2025 has a tree structure based on a mixture of over 295,000 computer chess games, played in the engine room of playchess.com and the best games played by humans (137,000).
The Reti Opening Powerbook was based on an average of at least 2300 games. This means that 137,000 games from Mega and correspondence chess exceeded the Powerbook’s entry threshold, plus 295,000 games from the playchess.com engine room. The original move order a la Richard Reti is 1.Nf3 d5 2.c4 followed by a fianchetto with g3 or b3 (or even the double fianchetto), but nowadays the term Reti opening is much broader and includes almost all possible variations after 1.Nf3 that do not go directly into well-known ‘grand’ openings. One plays 2.g3 (sometimes also 2.b3) more flexibly, usually followed by 3.Bg2 and 4.0-0. Depending on Black’s set-up, one then decides how to proceed. The Reti-Powerbook includes as many game openings as possible after 1.Nf3, but no variations with early d2-d4, which would lead to the Catalan or King’s Indian, for example. )
Ruy Lopez Powerbase 2025 is a database and contains a total of 12092 games from Mega 2025 and the Correspondence Database 2024, of which 1276 are annotated.

Top players such as Carlsen (5 annotated games), Caruana (12), Anand (38), Aronian (3), So (3), Kramnik (1), Nepomniachtchi (2), Karjakin (6), Giri (16), Radjabov (2), Firouzja (3), Vitiugov (4), Yu Yangyi (1) and Vidit (3), have analysed their own games with in addition annotations by Ruy Lopez experts like Marin (201) and Postny (129) etc. The total comes to 12092 games with an average rating of at least 2640 (apart from games with annotations or played by Ruy Lopez experts).
The Ruy Lopez Powerbook 2025 has a tree structure based on 3.6 million computer chess games played in the engine room of playchess.com.
