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. )

The most popular moves are 1…d5 2.g3 Nf6 3.Bg2 c6 4.0-0 and now Black has to choose between the almost equally often played 4…Bg4 and 4…Bf5. The latter seems to be a good choice because of the preservation of the bishop, but the Powerbook shows a path to an advantage for White: 5.c4 e6 6.Qb3 Qb6 7.d3.
